This is a senior, high-trust engineering role for someone who wants to build core systems properly, not inherit legacy or operate inside rigid delivery structures.
You'll be joining a small, engineering-led team at an early stage, working on a greenfield platform with long-term technical ambition. The focus is on building reliable, scalable software that will sit at the heart of a complex product.
This is not consultancy work and not feature factory delivery.
You'll have genuine ownership over how systems are designed, built, and evolved.
What you'll be doing
Designing and building core backend services and APIs
Contributing to architectural decisions that underpin future scale
Working across the full lifecycle, from problem definition to production
Building systems that prioritise reliability, performance, and maintainability
Collaborating closely with a small, senior team where quality matters
What they're looking for
Strong experience as a backend or backend-leaning full-stack engineer
Comfortable operating in early-stage, ambiguous environments
Experience building production systems that need to be robust and dependable
Pragmatic engineering mindset - knows when to move fast and when to slow down
Enjoys ownership, responsibility, and technical depth
Context
Early-stage, product-led business
Small, senior engineering team
High autonomy, low bureaucracy
Engineering decisions genuinely matter
- London fully onsite
- Uop to 120k + equity
