Senior DevOps Engineer

The project is a strategic initiative to deliver a new FX Swaps clearing capability, enabling atomic processing of swap packages within a highly regulated, low-latency clearing environment. The platform operates under strict resilience, latency ( 10 seconds SLA), and regulatory (EMIR) constraints. The DevOps function will play a critical role in ensuring high availability, automation, continuous delivery, and operational resilience, while supporting a transition towards cloud-enabled infrastructure. This is a mission-critical system requiring Cat 5 resilience, robust CI/CD pipelines, strong monitoring, and disaster recovery capabilities. The solution will initially be deployed on-prem, with future migration to AWS (multi-AZ, multi-region).
