We're working with a scaling, mission-driven consumer app business to find a Senior Software Engineer to join a small, high-ownership engineering team. They're backed by a major international organisation, which means real stability and resource, but the team operates with full startup autonomy - moving fast, shipping frequently, and owning what they build end to end.

As a Senior Software Engineer, you'll work comfortably across both backend and frontend, with a natural lean towards backend design and architecture.

  • Design and ship features across the full stack, writing clean, maintainable TypeScript on both backend and frontend.
  • Take a leading role in backend design, data modelling, and API quality as the platform scales.
  • Make pragmatic technical decisions that balance quality, speed, and long-term maintainability.

Solid full-stack experience with genuine depth on the backend: APIs, data modelling, system design, and a JavaScript background. Frontend experience in Angular, ideally with exposure to Ionic as the framework layer.

Competitive base salary plus annual bonus. Hybrid working: Private health scheme, 25 days holiday plus additional leave perks, flexible and remote-friendly working arrangements, and a dedicated training and development budget.

This is a strong opportunity for a pragmatic Senior Software Engineer who wants genuine ownership, a tight-knit team, and a product with real-world impact.
