Our client is a profitable, founder-led business with a decade of operating history and long-term enterprise relationships in a high-growth marketing vertical. They are now entering their next phase: expanding a technology platform built on proprietary data, deep category expertise, and an existing commercial foundation. The platform is AI-native, subscription-based, and serves organisations investing significantly in this space. This is a zero-to-one moment for a business that already has the customers, credibility, and revenue to back it up. The Role The team builds software differently. AI-native tooling is used to go from requirement to working product in days, not months. This isn't about prompting your way to a prototype, it means owning the full lifecycle: understanding what a customer actually needs, shaping the right solution, and shipping it yourself. As a Founding Engineer, you sit at the intersection of product thinking, technical depth, and delivery ownership, a combination that used to require three separate hires. This role didn't exist two years ago. AI tooling has fundamentally changed what a single person can own end-to-end, and the product team is built entirely around that shift. What You'll Do • Own discovery to delivery: Join customer and stakeholder calls, extract the real requirement underneath the stated one, then go build it. No handoff. No ticket queue., • Build with AI-native tools: Use the best available tooling to ship working software fast. Know when to generate, when to edit, and when to reason from first principles., • Make product decisions under uncertainty: Scope features sensibly, make the right tradeoffs between speed and correctness, and know when something is good enough to ship., • Test and hold quality: Think adversarially about your own work, cover edge cases, write the test, catch the bug before the user does. What They're Looking For Your primary instinct should be product: you think in users, workflows, and outcomes first. But you need enough technical depth to know what's hard, what's easy, what's a shortcut that will cost you later and how to actually build it. No requirement to be a senior engineer; what matters is that you've built things, understand how the layers of a system fit together, and aren't intimidated by code you didn't write. Curiosity matters more than credentials. Technical familiarity expected across: • Frontend vs backend tradeoffs, • REST APIs and data models, • Databases and data modelling basics, • Caching strategies, • Deployment environments (staging, production, CI/CD), • UI component libraries, • Authentication flows, • Performance fundamentals Nice to have: • Experience shipping in a startup or early-stage environment, • Comfort with ambiguity, • Side projects you actually finished, • Opinions about what makes software feel good to use The Details • Compensation: Market-competitive salary + annual bonus scheme, • Location: London-based office; team is mostly remote with regular in-person days, • Work authorisation: Must have existing right to work in the UK or EU; visa sponsorship not available, • Team: Small team of builders shipping end-to-end

About Euphoric: Euphoric builds AI-first employee benefits administration software for the world’s largest and most prestigious employers. Born out of Peppy Health — a fast-growing, category-defining Series B startup — we spun out in May 2025 to tackle a far bigger opportunity. Global employers spend $3–5 trillion on benefits every year. It’s their second-largest cost after payroll — yet the entire category is still running on legacy systems and outdated assumptions. The space is primed for transformation: despite its scale, it’s been almost completely overlooked by AI-first startups. Incumbents — including one U.S. heavyweight with $2B+ in annual revenue — are constrained by archaic tech stacks and can’t move fast enough to innovate. And this isn’t just a massive market — it’s genuine “tech for good.” Smarter benefits administration, richer analytics, and clearer communication have the power to directly improve the everyday lives, wellbeing, and financial security of millions of employees worldwide. We’re a sharp, high-velocity team with bold ambitions, obsessed with building category-defining technology and partnering with exceptional people who want their work to truly matter. We closed our seed round in October 2025 and are building from a position of strength with a long cash runway. The role: We’re looking for a Software Engineer to bring their ambition, creativity, and technical prowess to join our high-powered team to build the technology that powers the world’s first lovable, AI-native benefits platform. You’ll have real ownership, big targets, and a chance to help shape both the work you do and the company in general. We care less about traditional career paths and more about raw talent, bias for action, and how much fire you bring. What you’ll do: • Build AI-first features end-to-end: You’ll contribute to the design, deployment, and iteration of our next-generation benefits platform features that leverage personalization, experimentation, and AI/ML methods (e.g. agents/LLMs, recommender systems, reinforcement learning) to enhance user experience in a meaningful business domain., • Contribute across the tech stack: You’ll work in React (JavaScript/TypeScript) on the frontend and Python (FastAPI, SQLAlchemy) on the backend, shipping production-ready code and user-facing features in addition to innovative ML work., • Live on the cutting edge of AI tooling: You’ll help push the boundary of what’s feasible with modern AI-powered software development tools (Cursor, Windsurf), keep up with the regular drumbeat of AI advances, and find new and exciting ways to build and explore new features faster., • Participate in a fast-paced iterative environment: Collaborate closely with design, product, and beyond to deliver and iterate on impressive features and prototypes at world-class pace., • Keep code clean and well-tested: Maintain clean, efficient, and tested code with clear documentation for both peers and future reference., • Review, refine, and grow: Actively participate in peer reviews, CI/CD processes, and a growth-minded engineering culture, where you continuously seek to level up your technical skills., • Be a team player: Sometimes you’ll be iterating on ML pipelines; other times you’ll be refining a frontend component or fixing a tricky bug. We need someone who’s excited about the full product journey and moving together as one. Skills & experience: • Industry Experience (3+ years): Prior experience contributing to impactful products in fast-paced or startup environments, with an understanding of both scale and quality from larger tech organisations., • Hands-On Full Stack Skills: Proficiency in React/Typescript and/or Python (RESTful APIs, data pipelines), plus comfort with deploying and maintaining services on modern cloud platforms (GCP preferred, AWS or Azure also fine)., • Applied AI/ML Skills: First-hand experience building and delivering AI/ML features to real users, and an insatiable curiosity to keep up with emerging technologies and trends, • Team-Oriented Mindset: Strong communication skills for explaining complex ideas to technical and non-technical audiences, and a passion for collaborating within cross-functional teams., • Passion and Pride in Shipping: A do-whatever-it-takes attitude to deliver against important business goals that help the entire team win, • Pragmatic Best Practices: An overarching desire to build efficient, scalable, and maintainable code, while learning the tradeoffs between technical debt and delivery speed What we look for: We’re a great bunch but we have some "Euph" cultural non-negotiables. To do well here you will: • Thrive in fast-paced, feedback-rich environments, • Take your work seriously, but not yourself, • Be proactive, playful, and deeply curious, • Want to build something that matters, • Be willing to “do what it takes” What you’ll get: • Salary between £90k - £110k dependent on experience, • Remote-first setup with optional shared work space pass and hubs in London (We will only consider UK or Europe based candidates, with a preference for those closer to London), • Apple devices and the best AI tooling, • Private healthcare via Vitality, • 3% employer pension contribution (min 3% employee contribution), • Meaningful early-stage share opportunities, • 25 days holiday per year, plus bank holidays, • Career rocket fuel - real growth, real ownership, real impact

A well-established SaaS business within the construction technology space is seeking a hands-on Lead Engineer with a strong backend focus to take technical ownership of a proven platform entering its next phase of growth. The company has spent more than eight years building software that is actively used by professionals operating in demanding, real-world construction environments. The platform supports project tracking, cost management, operational workflows, and site delivery across a growing customer base. Following a significant rebuild of the product and strong recent commercial growth, the business is now scaling into larger enterprise-level construction customers. The technical foundations are in place, and the next phase is focused on scalability, system reliability, and continued product evolution. The Opportunity This role is suited to an experienced engineer who enjoys meaningful ownership and wants to play a central role in shaping how a product and engineering function evolves. You will take primary responsibility for the backend platform, working closely alongside an established frontend team and contributing to a wider ecosystem that includes both web and mobile applications with offline-first functionality. Key responsibilities include: • Maintaining platform stability and performance as usage scales, • Leading backend architecture and API design decisions, • Supporting scalability as new customers are onboarded, • Collaborating with product and business stakeholders to guide technical direction, • Balancing feature delivery with long-term technical improvements The role combines strategic thinking with hands-on engineering. You will have significant influence over how systems are built, improved, and scaled over time. What We’re Looking For Strong backend engineering experience is essential, ideally within modern PHP environments and production SaaS platforms operating at scale. Experience with: • REST API design and architecture, • SQL schema design and optimisation, • Modern backend frameworks (Symfony preferred), • Collaborative engineering environments and Git-based workflows Exposure to frontend technologies such as React and TypeScript is beneficial, although the primary focus of the role remains backend ownership and systems thinking. Most importantly, the business is looking for someone pragmatic, commercially aware, and confident in their technical judgement — someone motivated by ownership and long-term impact rather than simply feature delivery. Why This Role Stands Out This is an opportunity to join a stable, well-funded business with a proven product, genuine market demand, and strong long-term backing. The platform is already embedded within active construction environments and continues to gain traction with larger customers. The company is investing heavily into the next stage of growth, creating an opportunity for the right individual to play a highly influential role in shaping both the technology and engineering culture moving forward. There is also a clear pathway into broader technical leadership as the business expands, alongside long-term incentive alignment through equity participation. Summary This position would suit an engineer looking to move beyond pure development work into a role centred around ownership, technical direction, and long-term product evolution within a growing SaaS environment.

Note: no agencies/consultancies, must be in the UK with right to work We're building the digital infrastructure that makes clean energy work in the real world. Seventy million machines run on diesel. The alternatives exist. But the operations are complex, the supply chains are still emerging, and for most companies the transition feels risky. That's the problem we're solving. Logiq Systems builds the operational intelligence layer that makes clean energy work in the real world. One platform for fuel suppliers, rental companies, and asset operators to deploy, monitor, and optimise hydrogen, battery, solar, and alternative fuel systems — at the scale and reliability that industries actually need. We're live across construction, events, and industrial sectors with customers including Toyota, Balfour Beatty, Acciona, Sunbelt Rentals, and Protium. The technology works. Now we're scaling the team that scales the business. If you want to work on infrastructure that matters, in a company early enough that what you do shapes the industry, we'd like to hear from you. UNITED KINGDOM, REMOTE / FULL-TIME Role Summary: We are looking for a Senior Software Engineer (full-stack) to develop the Logiq platform. Working closely with our Head of Product, you will be responsible for building software that forms the core of our main business, as well as defining the long-term technical direction of Logiq Systems. Who we are today: Logiq Systems was founded in 2020 and is currently a team of five. Aran Bates and Ben Lindley are the founders, two friends turned colleagues. We are both dads of kids less than 5 years old (two each). Having both worked on this for two years self-funded (although now venture backed) we are driving a huge market shift in off-grid energy. While it is one that won't change with the speed of the AI bubble - this is infrastructure and hardware, not some Al wrapper over ChatGPT - it delivers sticky and lasting change with our customers and the industries we touch. As a team our passion and mission is improving the world around us, making it better for people and the planet. Our purpose pushes us to be the force of change in this industry. Not just in environmental sustainability by making the world less polluted from carbon, noise and poor air quality, but also in creating a supportive company flexible to the realities of modern life. A company with a diverse, equal, and respectful workforce. What does that really mean though? Well we recognise that talent can exist anywhere in the UK and that people have life commitments that can overlap with traditional 'core hours'. We are remote-first: As a team we are spread across the UK from Edinburgh to London, this means we can work with the best people out there. We also recognise the importance of building a sense of team, meeting regularly (at least once a quarter) and put a lot of emphasis into team building in the 'virtual' work environment also - e.g. daily team video calls, non- work Slack channels such as one specifically for sharing the music we are listening to. Although for this role there is a preference to have a candidate within around an hour of travel to Edinburgh or Oxford to work with the founders or the Head of product in person more regularly. Flexible working: To manage the interface of life and work we operate a flexible working policy, at the start of every week we have a whole team standup and in that we clearly communicate as a team what commitments people have that might cut into the working day or lead to a hard stop at the end of the day, so that as a team we can ensure that life and work fit together. Supporting women and primary carers in tech: Both Ben and Aran fully recognise the importance of building a supportive working environment for women and parents so they can continue a career, while remaining supportive and attentive to both kids and work. This has been heavily influenced through their experience as fathers and with partners who continue to have successful careers, while sharing parenting loads. The team we are building: The team we want to build is one where we are: • Passionate about making a difference. We are pushing change through a traditional market there meaning there are naysayers, so it is very important we have strong belief in the change we are driving., • Flexible and comfortable with ambiguity. We must be flexible as the market is early and developing. You will be shaping a new offering in the clean energy industry right from the start!, • Extremely self-motivated with a strong work ethic. We are a small team and need people to own their work. We also work hard because we love what we do!, • Fun! We need to enjoy what we do, while still being proud about the quality of our work., • Humble, authentic, and honest. We give credit where credit is due. We can respect, support and celebrate others for the value they bring., • Comfortable being challenged. We believe in creating an environment where we feel comfortable and safe enough for ideas to be challenged in a constructive manner., • Curious. Curiosity drives improvement and innovation. Always ask why. The Role: As a Senior Software Engineer, you will be responsible for the long-term technical direction of the Logiq platform and products, which provide real-time operational intelligence for connected clean energy assets. You will be designing and developing new products, features and improvements to the Logiq platform, delivering value to our growing customer base and the key capabilities required to evolve our growing business. As a senior member of the team, you will also have direct input into the product direction, working closely with the Head of Product to shape how Logiq develops as we scale. You will also be the champion of software engineering best practices across Logiq Systems. A few of your responsibilities: • Design and develop full-stack features using React, Python, PostgreSQL and serverless technologies (AWS Lambda, Fargate)., • Design and implement RESTful APIs and event-driven systems., • Maintain, extend and improve optimisation, alerting and forecasting models., • Implement and maintain CI/CD pipelines., • Ensure high-quality code through peer reviews, automated testing, documentation and adherence to software development standards., • Take ownership of the technical architecture and engineering processes., • Collaborate closely with a small startup team. To thrive in this role: We expect you to: • Be comfortable with variety and shifting priorities. Early-stage companies require adaptability, and you'll be working across very different types of tasks., • Take ownership of outcomes, not just tasks. You'll be given problems to solve, not always detailed instructions on how to solve them. We'll provide context and support, but you should be confident running with work and coming back with solutions or thoughtful questions., • Balance quality with speed. Early-stage work requires knowing when "good enough" is better than "perfect but late"., • Ask questions and challenge ideas respectfully. We value curiosity and constructive input across the team. We value people who bring their perspective and aren't afraid to ask "why?" or "what if we tried...?". Equally they are comfortable with their ideas also being respectfully questioned. We put the problem being tackled in the middle. What you'll need to do this job: • Full-stack: Proven experience in full-stack software development. We are using Python (REST & GraphQL) for the backend, React for the frontend., • Cloud architecture design: Proven experience in scalable cloud architecture design., • API design: Solid understanding API design (REST & GraphQL)., • SQL/NoSQL databases: Experience working with SQL (Postgres) and / or NoSQL databases., • AWS: Familiarity with the AWS Serverless stack and event driven architectures., • Customer Mindset: We value engineers who have a strong product and customer-centric mindset., • Communication: Excellent communication and collaboration skills to explain ideas clearly., • Collaborative and low-ego approach: You contribute positively to team culture and work well with others., • Agile: Comfortable with very lean/agile processes. We want you to be involved in all phases of the development lifecycle and bring your unique talents to the process., • DevOps: Experience with DevOps including setting up and managing CI/CD pipelines and terraform deployment., • AI enabled: Comfortable with leveraging AI to better assist developer workflows and rapid prototyping, • Testing: A strong testing mindset. If you think you meet most of the criteria, please get in touch! Experience we'd love to see: • Experience in developing high-scalability systems, • Experience with IoT data collection and processing pipelines. We are using a combination of Node-RED, MQTT, Telegraf, Linux, Python, InfluxDB and TimescaleDB., • Experience with integration of 3rd-party systems, • Experience with statistical modelling, ML optimisation & forecasting, • Strong data analytics skills, • Experience in early-stage start-ups, consulting, or high-growth environments where you've navigated ambiguity and taken initiative, • Experience working on (renewable) energy products or telemetry producing systems Location: • United Kingdom, Remote full-time, • We are remote first. We meet regularly (around once a quarter at least)., • We can’t currently support visas so you must have the right to work in the UK., • Preference for 1hr travel proximity to Edinburgh or Oxford to meet semi-regularly to work with founders or Head of Product. Remuneration: • £55,000 to £70,000/year salary depending on experience, • Share options in Logiq Systems

About the Company A profitable, founder-led business with ten years in the influencer marketing industry, serving leading consumer brands at scale. The company is expanding its AI-native, subscription-based technology platform built on proprietary data, enterprise relationships, and deep category expertise which is enabling brands and agencies to plan, execute, and measure influencer marketing at scale. The Role The product team uses AI-native tools to go from requirement to working product in days, not months. This means owning the full lifecycle: understanding what a customer actually needs, shaping the right solution, and shipping it yourself. A Product Engineer sits at the intersection of three disciplines that used to require three different people. What You'll Do • Own discovery to delivery: join customer calls, extract the real requirement, then build it. No handoff, no ticket queue., • Build with AI-native tools (Claude Code, Cursor, etc.) and know when to generate, when to edit, and when to reason from first principles., • Make product decisions under uncertainty: scope sensibly, balance speed and correctness, know when to ship., • Think adversarially about your own work: cover edge cases, write tests, catch bugs before users do. What They're Looking For Product-first instinct with enough technical depth to know what's hard, what's easy, and how to build it. You don't need to be a senior engineer, just someone who has built things, understands how system layers fit together, and isn't intimidated by unfamiliar code. Technical Familiarity Frontend/backend tradeoffs, REST APIs, data modelling, caching, CI/CD, UI component libraries, authentication flows, performance fundamentals. Nice to Have Startup experience, comfort with ambiguity, finished side projects, strong opinions on good software UX, background in creator economy or influencer marketing. The Details • Compensation: Market-competitive salary, • Location: London-based; mostly remote with regular in-person days, • Work Authorisation: Right to work in UK or EU required. No visa sponsorship., • Benefits: 25 days PTO, company days off, wellness days, L&D budget, annual bonus, paid sick leave.

Moodsonic uses sound to improve how indoor spaces feel. Our platform delivers adaptive soundscapes for workplaces, hospitals, universities, and other shared environments shaping daily life, integrating with hardware, building systems, and an array of applications to respond dynamically to activity levels, time of day, environmental sensors, and user input. The work sits at the intersection of audio, real-time systems, and human experience. The role We are hiring a Senior Software Engineer to own the backend that the entire product stack sits on: services, data layer, identity and authentication infrastructure, partner-facing integration APIs, device communication, and the security posture. You will own, evolve, and build the systems that power our internal tooling, customer-facing applications, partner integrations, and hardware deployments, strengthening what is already in production and shipping what comes next. You will be the technical lead on production engineering, security, and code quality, building on the foundations the team has put in place. As Moodsonic scales, you will keep the platform safe, reliable, and defensible. You are joining a team where colleagues hold deep domain knowledge. You will need to build trust, collaborate well, and lead through influence rather than authority. This is not a management role. The platform is live and growing quickly, with real customers and real consequences. What you'll work on In your first six to twelve months: • Own and evolve the backend platform: services, data layer, infrastructure, APIs. Strengthen what is in production today, design what is missing, and build what comes next, • Own the backend side of how our deployed hardware connects to the platform: ingestion, device authentication, fleet management, and remote provisioning. Visibility and input into on-device code decisions, because device security is platform security, • Own the identity, authentication, and account layer of the platform, • Own and operate our data protection posture across the platform: encryption in transit and at rest, key management, data lifecycle, and recovery, • Own the partner-facing integration APIs end to end, from design through operation. These are the surfaces our customers and hardware partners build against, and their reliability is our reputation, • Own the engineering practices that support our certifications and audit-readiness, • Establish and maintain the engineering standards (testing, review, deployment, monitoring, secure coding) that the team operates by, • Partner with the engineers owning the audio engine and frontend surface on the backend contracts their work depends on What we are looking for Required: • 5+ years shipping and operating production backend systems, including time on-call and in incident response. You know what it feels like when something breaks at 2am and you own the fix, • Operational resilience as a habit: you design for failure, build with recovery in mind, and treat incident learning as a driver of engineering quality, • Strong judgment in small-team environments. You have owned quality yourself rather than inheriting it from process. You can take high-level product, customer, or security needs and turn them into practical technical plans without a big PM or architecture layer handing you a spec, • Deep relational data modeling and schema design. Postgres or equivalent as a daily tool. Strong instincts for migrations, indexing, and query performance under load, • API design experience: you have built and maintained APIs that outlived their first version and you have opinions about versioning, compatibility, and contract discipline, • Identity and authentication systems experience: modern identity protocols (OAuth or similar), session management, role-based access, multi-tenant boundaries. You understand what breaks when these are wrong, • Security mindset in practice, not theory. You think about attack surface, threat models, and access control as a matter of course, with working knowledge of cryptography and data protection fundamentals, • Code quality and observability as habits. Tests, substantive review, documentation, and the instinct to measure how software behaves in production are part of doing the work, not chores after it, • Strong Python for backend services. Comfortable with SQL, Docker, at least one major cloud, infrastructure as code (Terraform, Pulumi, or equivalent), and modern CI/CD practices, • Modern AI development tools are part of how you ship. You stay current as they evolve, adopt what adds value, and use AI to go faster on work you already understand, which is why you catch AI mistakes before they become bugs, • Demonstrated technical leadership through influence, not authority: you raise the bar through code review, standards, and example, and you have earned trust from engineers who were there before you, • Pride in craft, proactive risk-flagging, and the instinct to raise quality bars rather than work around them. Intellectual honesty and the willingness to push back when the right answer is unpopular, • Clear written and verbal communication, particularly when working asynchronously across time zones Valued: • Designing systems that interface with deployed hardware: device fleets, provisioning flows, secure OTA updates, telemetry ingestion, • Shipping to enterprise customers, incident response commitments, and contractual security obligations, • Experience inside a compliance-driven environment (SOC 2, ISO 27001, HIPAA, or equivalent) or building for auditability as a default, • Kubernetes and modern container orchestration, • Additional backend language fluency (Node or TypeScript, Go, Rust) for polyglot service work, • Audio, signal processing, or real-time systems background, • AI and machine learning in product contexts: audio generation, personalization engines, training and serving pipelines Not required but welcome: • Interest in sound, music, acoustics, or the wellbeing applications of audio Team and how we work You will join a small, senior team distributed across the UK, Europe, and the US West Coast. We run a weekly product cadence, work asynchronously by default, and rely on clear written communication to stay aligned across time zones. Compensation and benefits Base salary £65,000 to £85,000, calibrated to experience. Equity will be a material part of the package. Benefits include private medical insurance for UK employees, 28 days paid holiday inclusive of UK holidays, flexible remote-first working. UK right to work is required. How to apply Send a short note, your CV, and links to work you are proud of. Please include three to five sentences on a production system, API, identity/auth, or platform hardening project you owned.

Lead Full-Stack Developer Location: Remote-first Type: Full-time Start: ASAP About Couch Heroes At Couch Heroes, we’re exploring new ground for the MMO genre. In a world where fantasy and ancient technology intertwine, players explore shattered realms, grapple across verticality, solve puzzles, and push back corruption, with progression driven by player expression and discovery. We envision bridging generations of gamers, creating a space where both coexist and journey together. We’re developing in Unreal Engine, in early production, with a team spanning multiple countries. We’re remote-first, based in the UK, and scaling to support a multi-year live-service roadmap. We value autonomy, curiosity, and collaborative ownership, and we’re looking for creators who want to help build something from the ground up. Sound like your kind of thing? We should talk. About the Job The web and platform layer of an MMO is what players interact with outside the game client: account systems, social features, community tools, content delivery, and the services that tie the live experience together. We need a Lead Full-Stack Developer who can own the architecture of these systems and build the engineering team that delivers them. You will report to the CTO and manage a growing team of web and platform engineers.

Establish deployment practices that support rapid iteration without compromising stability., • Make architectural decisions about service boundaries, data models, caching strategies, and API design that balance immediate delivery needs with long-term scalability., • Establish monitoring, alerting, and incident response practices using Grafana and Uptime Kuma or equivalent observability tools. Frontend Engineering • Build polished, responsive, and accessible interfaces using TypeScript, React, and Next.js, with Redux for state management and Zod for schema validation., • Collaborate with UI/UX design to ensure clean design-to-implementation handoff and user-centric workflows across platform features., • Ensure frontend systems are built for internationalisation, accessibility, and performance from the start. Platform Integration • Work with gameplay engineering and online services to define how web platform systems integrate with the game client: authentication, account management, social features, content delivery, and analytics., • Collaborate with production to manage scope, schedules, and task breakdowns for web engineering work. Contribute to milestone planning, sprint scoping, and capacity forecasting. Must-Haves • Proven experience in software development, with at least one shipped product or live service., • Proven experience in a senior or lead role with hands-on team leadership experience: running 1:1s, setting goals, conducting reviews, and developing team members., • Strong backend experience with TypeScript, Node.js, and Express for API development., • Production experience with MongoDB and Redis in a services environment., • Strong frontend experience with React and Next.js., • Working knowledge of Docker, Kubernetes, and CI/CD pipeline design., • Experience with Azure Cloud services or equivalent cloud platform., • Strong communication skills and a collaborative working style, with proven experience making architectural decisions in cross-functional teams.
