We’re partnering with a fast-growing fintech rebuilding the infrastructure behind modern wealth management. Their platform is replacing legacy adviser and investment systems with API-first tooling designed for speed, transparency, and automation, giving financial advisers a far better way to manage investments at scale. Following a major funding round, they’re now hiring a Lead Backend Engineer to help shape the next phase of the platform and lead a small, high-performing engineering team.

What makes this role interesting:

  • You’ll work on core platform architecture, not peripheral features
  • High ownership environment with direct influence on product and technical direction
  • Opportunity to modernise systems in an industry still dominated by outdated technology
  • Small engineering team where strong technical decisions have immediate impact
  • Blend of hands-on engineering and leadership, ideal for someone who still loves building

The role:

This is a true player-coach position: around 50% hands-on engineering and 50% technical leadership. You’ll:

  • Lead and mentor a team of 3–4 engineers
  • Design and scale backend services powering an API-driven investment platform
  • Translate ambiguous business problems into clear technical execution plans
  • Drive engineering standards, architecture decisions, and delivery practices
  • Partner closely with product and leadership teams as the platform scales

What they’re looking for:

  • 8+ years of commercial Python engineering experience
  • Strong experience building backend systems and APIs in production environments
  • Previous experience leading engineering teams
  • Background in insurance, trading, fintech, or other regulated financial environments
  • Ability to balance short-term delivery with long-term technical quality
  • Comfortable operating in fast-moving, high-ownership environments

This role will suit an experienced backend engineer who enjoys solving complex domain problems, leading from the front, and building systems that directly shape a company’s future.
