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.

📍 Remote | Full-time 👋 Overview We’re looking for a pragmatic Full Stack Engineer who can lead the evolution of our infrastructure while keeping systems simple, reliable, and maintainable. This is a remote role for someone who enjoys owning infrastructure decisions without stepping away from hands-on product development. Medify Engineering is a team of ten engineers across two teams, and everyone is hands on, including engineering management and the CTO, which helps us keep our processes practical and engineer-friendly. We work to minimise meetings: engineers typically have a 15-minute daily standup for in-progress updates and quick alignment with Product, plus (per two-week sprint) a one-hour refinement with Product, a one-hour planning session with engineering, and a 30-minute company-wide demo. Operational work like deployments, bug triage, and on-call is handled on a rotation, with each person covering one week roughly every two months. 🔧 The Role In your first few months, you’ll focus on migrating our production environment from Heroku to AWS. Specifically, you’ll take our nascent ECS Fargate and Aurora Serverless v2 setup and turn it into our primary production environment. This is not a greenfield project; the foundations are in place with Terraform, and your role is to take the migration across the finish line. Once the initial migration phase is complete, you'll transition back to feature development, while continuing to own infrastructure decisions and improvements as they come up. This isn't a pure infrastructure role - it's a full stack position where you happen to be the person who deeply understands how our systems run. 🚀 What You’ll Do • Lead the migration of our production environment from Heroku to AWS, • Mature and own our ECS Fargate and Aurora Serverless v2 infrastructure, • Extend and maintain our infrastructure-as-code setup using Terraform, • Balance infrastructure ownership with ongoing full stack feature development, • Make pragmatic architectural decisions that prioritise reliability and simplicity 🧠 What We Value We've been paged fewer than 10 times this year - mostly for third-party outages or job queues that self-recovered within minutes. We want to keep it that way. We're not interested in over-engineered solutions or astronaut architecture. We want infrastructure that works reliably, is easy to understand, and doesn't wake anyone up at 3am. Developer experience matters here. If something makes deploys faster, reduces cognitive load, or eliminates a whole class of problems, we're interested. If it's clever for clever's sake, we're not. 🧩 What We’re Looking For • Experience working with AWS and scaling production applications, • Hands-on experience with Terraform, or other infrastructure-as-code tools you can translate from, • Strong full stack fundamentals and a clear understanding of how applications work end-to-end, • A bias toward simple, maintainable, well-understood technologies, • An engineer who designs systems with reliability and on-call sustainability in mind 🎯 Why This Role Works You’ll own a meaningful infrastructure migration, make architectural decisions that impact the whole team, and then return to varied and engaging product work - without being locked into an infrastructure-only silo. 🎁 What We Offer • Competitive salary: £70,000–£85,000, depending on experience, • Fully remote role with flexible working hours, • 25 days’ annual leave, rising to 28 days over three years, • Pension scheme, • Professional development sponsorship (courses, conferences, learning budget), • Matched charity funding, • Private health and dental care after one year of employment
