Senior Software Engineer

£85,000 - £95,000 + Bonus & Benefits

Hybrid | Central London (1 day per week)


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.


The product is a consumer app used by hundreds of thousands of customers globally, and the engineering team deploys multiple times a day. As a Senior Software Engineer, you'll work comfortably across both backend and frontend, with a natural lean towards backend design and architecture. The team values pragmatism over perfection - you'll be expected to make sensible calls, move things forward, and not get lost in the weeds.


Responsibilities:

  • Design and ship features across the full stack, writing clean, maintainable TypeScript
  • Backend Leaning with Nest.JS or Node.JS
  • Take a leading role in backend design, data modelling, and API quality as the platform scales
  • Contribute to infrastructure and CI/CD pipeline decisions in Azure
  • Work closely with the Head of Engineering, product, and design on roadmap delivery
  • Make pragmatic technical decisions that balance quality, speed, and long-term maintainability


Requirements:

  • Solid full-stack experience with depth on the backend: APIs, data modelling, system design
  • Frontend experience in Angular/React, ideally with exposure to Ionic as the framework layer
  • An engineer who can weigh trade-offs sensibly and keep delivery moving
  • Familiarity with Azure CI/CD pipelines and monorepo tooling is a strong advantage
  • Clear communication skills and the confidence to take ownership of decisions


Benefits:

  • £85,000 - £95,000 + Bonus & Benefits
  • Hybrid working: 1 day per week in Central London
  • Private health scheme
  • 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. If that sounds like the right fit, apply below or get in touch directly.
