Role: Senior Back End Engineer
Salary: Up to £100,000 + 10% bonus + equity
Location: London (Moorgate), hybrid working - 2 to 3 days per week onsite

- Take ownership of services throughout their full lifecycle, from architecture through to production support.
- Work closely with Product and Engineering teams to deliver high-impact features at pace.
- Drive adoption of AI-assisted engineering workflows to improve developer productivity.
- Champion engineering quality through testing, automation and modern software development practices.
- Contribute to architectural decisions as the platform continues to scale.
- Play a key role in shaping engineering culture, with a clear pathway into technical leadership.
What you'll need
- Strong commercial experience building production backend services with Python and FastAPI.
- Experience working within fast-growth startups or scale-ups, ideally through Series A or Series B growth.
- A track record of owning significant areas of a product and delivering features end to end.
- Experience working within high-performance engineering teams that value speed, ownership and quality.
- Actively use AI coding tools such as Claude Code, Cursor or similar as part of your day-to-day development workflow.
- Passion for improving engineering productivity through automation, tooling and agentic development practices.
- Strong understanding of API design, asynchronous Python and backend architecture.
- Experience working with SQL databases and modern data persistence layers.
- Ownership mindset with responsibility for testing, quality and production reliability.
- Interest in progressing into a Lead Engineer role as the engineering team continues to grow.
This role would suit a backend engineer from a fast-growth SaaS or technology scale-up who's looking to step into more technical leadership, embrace AI-native software development and help build a business with ambitions far beyond traditional SaaS.
