Lead Software Engineer

I’m hiring! Lead Software Engineer | Java | AWS | AI | System Architecture | Kafka | 2 days a week in London| £100,000 + Benefits

Love leading engineers, but not ready to hang up your coding gloves?

I’m partnering with a brilliant FinTech business doing something a little different and building a product that actually let’s people experience what it’s actually like to work in Trading, Banking and Quantitative Finance.

They’re growing, evolving their platform, and looking for a Lead Software Engineer who still really likes being a software engineer.

What will you actually do?

  • Write Java/Spring Boot code most weeks
  • Lead, support and unblock a small engineering team
  • Make architecture decisions alongside a hands‑on CTO and Principal Engineer
  • Get stuck into distributed systems, event‑driven services, APIs and AWS
  • Make CI/CD, testing and releases better (and ideally less exciting)
  • Work across Docker, React/TypeScript and real‑time technology
  • Experiment seriously with AI coding agents – they’re already part of how this team builds software

Necessary experience with:

  • Java/ Spring Boot
  • AWS
  • Kafka
  • System Design & Microservice Architecture
  • AI tooling experience

Desirable:

  • React
  • GDPR Knowledge | Experience working in the finance sector

This would be a great role for anyone who knows Java inside and out, had led engineers formally or unofficially and likes solving technical problems. This is a brilliant role for someone who has opinions about good software architecture and can explain why, can actually use AI coding tools and enjoys the autonomy of figuring things out.

A financial background is not necessary, but an interest into how markets work would be great.

Experience working in a smaller team or startup/ scale environment would be desirable.

£100,000 + Benefits and a flexible working environment within a genuinely tech for good business.
