Technical & Solution Architect (Distributed Ledger / Regulated Financial Services)

As a Technical & Solution Architect, you will lead the design of a distributed ledger-based post-trade platform in a regulated financial setting. You start hands-on as a senior engineer and progressively own system architecture, solution design, and technical direction. You will collaborate across product management, engineering, and client-facing discussions to shape a scalable, compliant product. This role offers ownership in a small, high-calibre team and exposure to cutting-edge market infrastructure, with a clear path to a formal architect position. You will influence product direction through strong technical insight and cross-functional communication.
