The platform supports issuances totalling over a trillion euros annually. Foundational services are already in place; the focus now is on expanding into core business features such as Sales screens, hedge workflows, and allocation processes. The work is delivered incrementally, with a strong emphasis on small, testable changes, frequent feedback, and sustainable pace.
Engineers in this role:
- Work primarily in mobs, sharing ownership of design and code
- Build, test, and evolve services with a strong focus on clarity, simplicity, and maintainability
- Support the platform in production, using incidents and defects as opportunities to improve system design and resilience
