*Drive adoption of scalable cloud-ready solutions aligned with the bank’s overall data strategy.
*Collaborate with quants, trading desks, data engineers, and platform teams to deliver performant, reliable systems.
*Take a leadership role in growing and mentoring a new engineering team as the platform matures.
*Influence long-term architectural decisions and technology choices across the data estate.

*Knowledge of distributed systems, microservices, or cloud-native architectures.
*Experience implementing testing, CI/CD, and automation in modern engineering setups.
*Excellent communication skills with the ability to work closely with Front Office and quant stakeholders.
Desirable
*Experience in Equities or Equity Derivatives data sources, analytics, or trading workflows.
