About the Role
We're looking for a Lead Backend Engineer to join and lead our Payments Team.
This is a hands-on leadership role combining backend engineering, technical ownership, and team leadership. The Payments Team owns one of the most business-critical domains at InvestEngine, responsible for payment flows, external provider integrations, transaction reliability, and operational efficiency.
The team is entering an exciting stage where we are looking for a strong technical leader who can help simplify complex systems, improve reliability, drive architectural improvements, and scale both the platform and the team.
What You'll Do
- Design, develop, and maintain backend services in Python 3.11 using Django / DRF
- Lead technical initiatives across payments infrastructure and integrations
- Drive improvements in system reliability, observability, and operational excellence
- Work closely with Product, Operations, Compliance, and external partners
- Investigate production issues and identify root causes rather than temporary fixes
- Improve legacy systems and reduce technical debt
- Lead architectural discussions and technical decision-making
- Mentor engineers through code reviews, pairing, and technical guidance
- Take ownership of delivery, planning, and execution of complex projects
- Help grow and develop the engineering team
