- Contributing to a platform designed as a single source of truth across teams
- Automating manual processes and enabling faster product and workflow rollout
- Collaborating closely with engineers and front office users

- Python (core focus), some Java and React (experience not essential)
- Messaging systems and distributed architectures
- MongoDB (core data store), some Oracle
What we’re looking for
- Strong Python backend engineering experience in production environments
- Experience building and operating complex, business-critical systems
- Solid understanding of system design, data flows, and distributed systems
- Comfortable working in evolving platforms with multiple stakeholders
- Financial services experience is helpful but not required if candidates can show a genuine interest and conceptual understanding
