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.
