You sweat the details. You open a SaaS app and immediately notice the component that shouldn't be a modal, the auth flow nobody thought through, the table that takes half a second too long to load. Most engineers file a ticket. You fix it — and then you make sure it never happens again. That instinct is exactly what this team needs. The company This is an AI‑native integration layer for SaaS products and agents: unified APIs, MCP‑friendly tooling and A2A (agent‑to‑app and app‑to‑app) bridges so builders can wire their products into hundreds of third‑party tools without hand‑rolling every integration. It handles managed auth, real‑time observability and connector sprawl so product teams can focus on great agent experiences instead of glue code. Your job is to make the surface they see feel as well‑engineered as the plumbing underneath. Why this role exists The product experience is the brand. This is the first dedicated UX Engineer role — you’ll be the in‑house authority on taste, polish and performance. You won’t be one of many contributors to the front end; you’ll set the standard everyone else works to: the component library, the design system, the micro‑frontend architecture, and the AI rules and tooling that let the rest of the team move fast without making a mess. As the CTO put it in conversation: “It’s about setting the processes, the libraries, the tech stack… spreading the knowledge so that everyone can go to 90% of your level.” What you’ll actually do • Own the design system – define the visual language, build reusable primitives, and maintain the libraries that power every interface., • Ship pixel‑perfect UI in React, with real ownership of theming, performance and motion., • Make performance a feature – instrument Core Web Vitals, set bundle budgets, optimise hydration patterns and chase performance where it actually matters., • Be the voice of quality – host design critiques, push back on product design when it matters, and be the person who asks “what happens in this edge case?”., • Prototype and validate – turn product ideas into interactive proofs‑of‑concept that help PMs and designers converge on the right answer fast., • Lift the whole team – create AI‑powered tooling and internal rules so every engineer can contribute to the front end at your level. The split is roughly 70–80% front end, 20–30% back end (Node, React‑router, SvelteKit) — enough to remove performance bottlenecks without being a full‑stack role. Who you’ll work with You’ll report directly to the technical leadership and work most closely with the Product Manager and Product Designer day‑to‑day. The team is fast, flat and product‑focused: engineers own their features end‑to‑end and interact with product directly, so your decisions will show up quickly in what customers use. Must‑haves • 4+ years professional front‑end engineering, with a portfolio that shows you care about the details., • React & TypeScript at production scale (hooks, suspense, server components)., • Deep CSS fluency (Tailwind or equivalent) and modern browser APIs., • A strong UX sense for B2B SaaS flows — you’ve lived through auth flows, billing pages and dashboards, and you know where the traps are. Nice to have • Svelte, Web Components or other framework experimentation., • Experience with auth flows (OAuth2, OpenID Connect) and secure front‑end patterns., • Prior work on B2B developer tools or dashboards at the seed‑to‑Series‑B stage. What’s on offer • £80,000–£100,000 base + annual company performance bonus., • Meaningful EMI share options., • £15/day lunch budget when working from the London office, • £1,000 home office setup + £500/year top‑up. If you read this far and you'd like your CV reviewed by a human, email mark@seekr.inc with "Watch me React" in the subject line. A couple of lines on why you think this might be a good fit — that's all.

Roles & responsibilities: Power BI Development & Data Modelling • Design, build, and optimise Power BI reports and dashboards from concept through to production deployment, across all business domains., • Develop complex semantic models with production-quality DAX - including advanced time intelligence, calculation groups, UDFs and performance-optimised measures at scale., • Write advanced M / Python transformations, including custom functions, parameterised queries, and API connections to source systems., • Manage model definitions using TMDL under source control (GitHub), following proper branching, review, and release practices. Data Integration & Pipeline Development • Build and maintain automated data pipelines (SQL, Power Platform, Azure Data Factory) that replace manual, spreadsheet-heavy reporting workflows., • Write complex SQL queries, stored procedures, and views to extract and transform data from ERP, commercial, and project control systems., • Integrate and normalise fragmented data across multiple source systems to deliver a reliable, reconciled analytical layer., • Configure streaming and real-time datasets for operational reporting that reflects current state, not yesterday’s extract. Construction Reporting Logic • Apply working knowledge of construction commercial and operational processes to ensure reports reflect how work is delivered and managed., • Challenge data that doesn’t align with construction reality and work with source system owners to fix it at the root. Quality, Governance & Documentation • Implement automated validation and exception-reporting layers to catch discrepancies before data reaches stakeholders., • Maintain data dictionaries, lineage documentation, and a technical data catalogue so that metric logic is transparent and not dependent on any single individual., • Apply row-level security, workspace governance, and enterprise refresh scheduling standards., • Manage all BI assets through governed deployment pipelines across development, test, and production environments. Stakeholder Partnership & Self-Service Enablement • Work directly with finance, commercial, operations, and project teams to understand priorities and translate them into actionable reporting outputs., • Build reusable, self-service reporting layers that reduce dependency on the central BI function for standard queries., • Communicate clearly what a report shows, what it doesn’t, and what caveats apply — in language stakeholders understand. Credentials • Degree in a quantitative or technical discipline (e.g., Mathematics, Engineering, Data Science, Finance) or equivalent demonstrated practical experience., • Evidence of continuous learning — recent certifications or a portfolio demonstrating advanced proficiency in Power BI, DAX, TMDL, and at least one of R or Python. Essential Skills, Knowledge, Experience, Behaviours Skills & Knowledge Power BI & DAX • Expert-level DAX: complex measures, advanced time intelligence, calculation groups, and model performance optimisation (DAX Studio, Tabular Editor), • Expert-level M / Python: advanced transformations, custom functions, parameterised queries, API connections, custom visuals., • Strong working knowledge of TMDL for semantic model version control, • Deployment pipelines across dev, test, and production environments, • Streaming and real-time datasets for live operational reporting SQL & Data Engineering • Strong SQL: complex queries, stored procedures, views, and CTEs for extraction and transformation., • Experience building automated data pipelines using SQL, Power Platform, or Azure Data Factory., • Experience of Power Platform (Apps, Automate, Pages ideally with HTML, CSS, React knowledge) Data reconciliation across enterprise data systems and project control systems with no pre-existing single source of truth. Source Control • GitHub (or equivalent): managing BI code, TMDL definitions, and deployment pipelines with branching, review, and release workflows Statistical Analysis • R or Python for descriptive and inferential statistics, trend analysis, variance analysis, and data exploration in support of commercial insight Construction Knowledge • Working understanding of construction commercial processes: CVRs, cost-to-complete, revenue recognition, margin analysis, subcontractor accounts., • Familiarity with programme management data: float, critical path, earned value, and how reported progress relates to reality on site., • Awareness of how construction projects are financially structured: prelims, measured works, variations, provisional sums, retention. Communication • Clear, precise communication: able to explain what a report shows, what it doesn’t show, and what caveats apply., • Comfortable working directly with senior stakeholders across finance, commercial, and operations. Experience • Extensive experience of hands-on Power BI development in a complex, multi-system enterprise environment., • A demonstrable background of data engineering, semantic models, sql query, web scraping, with direct exposure to commercial and operational data., • Demonstrated track record of replacing manual, spreadsheet-heavy reporting with automated, governed BI solutions., • Experience reconciling and normalising fragmented data across ERP, commercial, and quality systems., • Proven ability to work autonomously at pace, managing competing priorities without sacrificing accuracy. Behaviours • Technical Rigour: You treat every output with the understanding that a single discrepancy erodes trust in the entire reporting function. Accuracy is non-negotiable., • Operational Intuition: You interpret data through its real-world context and proactively flag numbers that don’t align with construction reality., • Root-Cause Orientation: You refuse to paper over data quality issues in the reporting layer. You challenge and fix problems at the source., • Self-Directed Delivery: You manage your own workload, prioritise effectively, and deliver at pace without needing close supervision., • Engineering Pragmatism: You know when to provide a rapid tactical answer and when to invest in a properly engineered long-term solution., • Continuous Improvement: You actively seek better ways to build, automate, and govern reporting — and stay current with the Microsoft data stack.

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. You will make architectural decisions, stay hands-on with code, and represent the web engineering discipline across the studio in production planning and resourcing decisions. We are in early production. The studio has been running for three years, and core platform infrastructure is being built alongside the game itself. You will be making foundational choices about stack architecture, service boundaries, deployment pipelines, and data models that the team builds on for years to come. This is not a maintenance role. You are building systems from the ground up. Your Role People Leadership and Team Development • Manage a growing team of engineers as the team scales through production: set priorities, assign work, balance workload, and run regular 1:1s focused on progress, career development, and honest feedback., • Lead performance reviews and goal setting aligned to production milestones and individual development plans. Identify skill gaps and address them through coaching, stretch assignments, or training., • Represent the web engineering discipline in cross-discipline leads meetings, production planning, and resourcing conversations. Advocate for team needs and capacity., • Foster a team culture of code quality, shared ownership, and continuous improvement., • Support hiring as the team grows: contribute to job descriptions, review technical submissions, and participate in interview loops. Technical Leadership and Architecture • Architect and lead the development of backend microservices using TypeScript, Node.js, and Express, with MongoDB for persistent storage and Redis for caching, session management, and pub/sub messaging., • Design scalable, well-bounded services that support the throughput and reliability demands of a live-service MMO: player accounts, social systems, marketplace, mail, inventory, and platform integrations., • Own CI/CD pipelines using Azure Pipelines, with Docker and Kubernetes on Azure for container orchestration and deployment. 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. Nice-to-Haves • Experience building backend services for games, social platforms, or real-time multiplayer applications., • Experience with Redux, Zod, or equivalent state management and validation libraries., • Familiarity with real-time communication systems: WebSocket at scale, pub/sub architectures, or event-driven service design., • Experience with Grafana, Uptime Kuma, or equivalent observability and monitoring tools., • Experience with OAuth2/JWT authentication flows and identity management., • Experience with Golang or additional backend languages., • Contributions to open-source projects or technical writing that demonstrates systems thinking. About You • You lead by example. You are hands-on when needed and empowering always., • You build systems that last and take pride in readable, maintainable code., • You are comfortable translating product vision into technical decisions and explaining technical constraints to non-technical stakeholders., • You are comfortable working through ambiguity. Early production means not everything is defined yet, and you see that as an opportunity to shape the right architecture., • You balance engineering ideals with delivery pragmatism. You know when to build for the future and when to ship what works., • You work autonomously in a remote environment, proactively keeping your team aligned and your stakeholders informed., • We are committed to making our hiring process accessible.
