Software Engineer

£60,000 - £80,000 + equity

Hybrid | London (remote considered for the right person)

We're working with a well-funded early-stage startup building a consumer platform in a fast-moving, regulated market. Funding is in place, the product is coming together, and they're ready to bring in their first engineering hires.

As a Software Engineer, you'll take on real problems immediately, helping set the architecture, feeding into product calls, and choosing how things get built rather than picking up decisions already made. It's a backend-weighted Software Engineer role centered on systems that have to stay fast and dependable when traffic spikes, so responsiveness and stability are the interesting parts of the job. You'll sit in a small founding group with real autonomy and a clear route into technical leadership as headcount grows.

Responsibilities as a Software Engineer:

Build systems that need to hold up under load, where keeping things quick and stable is the genuine challenge

Write and maintain backend services on the JVM, mainly in Java

Create clean, responsive interfaces on the front end using React

Deliver live, continuously updating experiences for users

Take a share of ownership over infrastructure and the route to production

Influence the wider architecture and weigh in on product direction

Make heavy use of AI tooling across how you design, write and ship code

Requirements:

Strong commercial time on the JVM stack, ideally in Java

A mid-level engineer who wants ownership and doesn't need close management

Track record with performance-sensitive or low-latency work

Sound on DevOps, infrastructure-as-code and deployment pipelines

At home in an early, ambiguous startup where you take the lead and iterate

The Package:

Starting salary between £60,000 - £80,000

Real equity, so you benefit from what you help create

First-engineer ownership across architecture, tooling and direction

Hybrid setup, around a day a week in a central London workspace, with real give

A clear path into leadership as the team builds out

A genuine investment in AI tooling, with regular internal AI sessions

This is a rare chance to be the first Software Engineer somewhere the early technical calls still shape everything, with a real challenge attached and equity that actually counts. If you want ownership, influence and hard performance problems to get your teeth into, we'd like to hear from you as their next Software Engineer.
