Senior Full Stack Engineer (TypeScript/Backend-Focused) | High-Growth Digital Prize Platform
Techfellow Limited

À propos
Role Overview We’re supporting a fast-scaling digital platform operating in the online prize and gaming space, as it strengthens its core engineering team in London. The business has already built a robust, high-throughput platform and is now focused on scaling, optimisation, and feature delivery as it continues its rapid growth. This is not a traditional “full stack” role. The emphasis sits firmly on backend and platform engineering, with the expectation that you can contribute across infrastructure, data, and occasionally front-end/mobile when required. You’ll be working within a small, high-impact team, taking ownership of production systems, improving performance under load, and helping evolve a mature architecture rather than building from scratch...
Key Responsibilities
Develop and enhance backend services using modern TypeScript runtimes, focusing on performance and reliability
Work across the full platform stack, including infrastructure, databases, and application layers
Improve and extend an existing system, supporting ongoing product and commercial roadmap delivery
Optimise data access patterns and database interactions within a high-concurrency environment
Implement and refine caching strategies to maintain performance at scale
Contribute to mobile and front-end layers when needed, particularly around feature delivery
Own deployments, environments, and system behaviour across containerised infrastructure
Strengthen CI/CD pipelines, testing coverage, and release processes
Ensure robust security practices across application and data layers
Collaborate closely with product and commercial teams to enable real-time features and integrations
Continuously enhance system observability, performance monitoring, and developer tooling
What You’ll Bring
5-9 years’ experience in software engineering, with a strong backend/platform bias
Deep expertise in TypeScript and experience building scalable backend services (Node, Bun, or similar)
Solid experience working with relational databases and ORM-based data access patterns
Practical knowledge of caching technologies such as Redis in production environments
Exposure to infrastructure and deployment workflows (Docker, cloud platforms, or similar)
Exposure to observability tooling or distributed system monitoring
Experience contributing to production systems in high-growth or high-traffic environments
Ability to work independently, take ownership, and contribute without heavy oversight
Strong systems thinking - understanding how changes impact performance, scalability, and reliability
(Preferred) Experience in payments, gaming, or regulated digital platforms
(Preferred) Interest or experience in applying AI tools to improve engineering workflows
