Senior Front-end Developer (AI-First SaaS Platform) Compensation: Competitive, based on location and experience Location: Turkey — Hybrid (Istanbul office 1 day/week + remote) Keepnet is an AI-driven SaaS platform helping organisations manage human cyber risk at scale. We’re growing strongly in the UK with increasing global momentum. With Agentic AI live in production, Keepnet runs autonomous systems that plan, build, and operate security awareness and human risk workflows — supported by strong guardrails, auditability, and observability. We’re looking for a Senior Front-end Developer who wants to build production-grade web experiences that power these systems — in an AI-first engineering team where quality, ownership, and long-term thinking matter. What You’ll Do • Build and own key parts of Keepnet’s web application (Vue/Nuxt), including performance, reliability, and maintainability., • Design and develop clean, modular UI components and shared packages (design system patterns, reusable modules)., • Implement AI-driven user experiences: human-in-the-loop approvals, guardrails-aware UI, clear feedback loops, and audit-friendly flows., • Integrate with internal APIs (and relevant third parties) to enable automation, reporting, and security workflows., • Create resilient UX for async workflows (jobs, queues, long-running tasks): polling, retries, idempotent actions, progress states, and error recovery., • Improve and maintain frontend observability (client-side logging, metrics, tracing where applicable; tools like Sentry) to prevent incidents rather than react to them., • Write and maintain automated tests across levels (unit/component and E2E) to increase release confidence., • Collaborate closely with Product, Design, Backend, and Customer-facing teams to ship features that solve real customer problems., • 5+ years building modern web applications for production SaaS., • Strong experience with Vue.js (Vue 2 & Vue 3) and Nuxt (Nuxt 2/3). (If you’re strong in Vue and can ramp quickly on the other, that’s ok.), • Solid knowledge of TypeScript, modern JavaScript, and browser fundamentals., • Strong understanding of API integration and real-world frontend architecture (state management, routing, data-fetching patterns, error handling)., • Ability to build for reliability: monitoring, debugging, incident hygiene, and continuous improvement., • Experience improving performance (Core Web Vitals, bundle optimization, SSR/CSR trade-offs, caching strategies)., • Experience with frontend testing (unit/component + E2E) and setting pragmatic quality bars., • Comfortable taking ownership beyond deployment: you ship it, you support it., • Hands-on experience using AI-assisted development and design tools such as Cursor, Figma Make, or similar — using AI daily for coding, refactoring, UI generation, and iteration, while maintaining strong engineering judgment and code quality. Nice-to-haves • Experience with Azure-based delivery pipelines (CI/CD) or cloud-native environments., • Experience with design systems (Storybook), and strong collaboration with Figma workflows., • Familiarity with accessibility (WCAG) and internationalisation (i18n, including RTL languages)., • Familiarity with React (helpful for cross-team collaboration, not required). Security mindset (important) • You build systems that are secure by design: XSS/CSRF awareness, safe auth/token handling, dependency hygiene, and careful data display. Tech Stack (Current) • Frontend: Vue (2 & 3), Nuxt, • Cloud / Delivery: Azure (CI/CD), • Observability: Sentry (and related logging/monitoring patterns) (We don’t expect you to know every tool on day one — we care about fundamentals and ownership.) Life at Keepnet Engineering at Keepnet is about craft, collaboration, and impact. What you can expect: • Hybrid working: In-office collaboration + remote focus time, • Thoughtful engineering: Time to design systems properly, not just ship quickly, • Global context: Work on a multinational platform used across multiple regions, • AI-first environment: AI-assisted development and production-grade AI systems are part of everyday work, • Team culture: Monthly team lunches and quarterly offsites, • Care about clean architecture, maintainability, and product quality, • Enjoy working with experienced peers who challenge each other constructively, • Prefer preventing incidents over reacting to them, • Want to build software used by real customers at real scale, • Believe good engineering is as much about ownership and judgment as it is about code If that sounds like you, we’d love to talk.

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. If you require reasonable adjustments at any stage, please let us know. Couch Heroes have partnered with Skillsearch on this hire.
