Role Context & Responsibilities:

We are building a new issuance platform to replace a legacy bookbuilder. The system is akin to a real‑time trading platform, used by ~1,000 global users who add and remove orders in real time during a tight ~5‑hour execution window. 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
