Join a Team Redefining Modern Banking Technology! Our client is a Swiss bank focused on delivering advanced online trading and financial services.

Technology & Engineering Culture We continuously evolve our systems toward: * Atomic, independently deployable microservices * Self‑contained applications with clear ownership * Dockerized environments * Automated CI/CD pipelines Engineering decisions focus on reliability, transparency, and scalability, supporting business‑critical banking systems.
