Site Reliability Engineer (SRE) - Security

Platform Engineering at IMC Trading builds and runs the core platforms that power our business. This Site Reliability Engineer role within Platform Engineering is focused on security projects: embedding security into system design and infrastructure to protect and accelerate our rapidly evolving technology landscape.

As a bridge between application development and production operations, Platform Engineering enables and applies security by design: embedding controls, guardrails, and secure defaults directly into our platforms and infrastructure. You will implement security into IMC systems in ways that reduce friction and raise our baseline of safety and reliability.

We are hiring a Site Reliability Engineer within Platform Engineering to drive security-focused initiatives across IMC. You will collaborate closely with most technology teams, operate with high autonomy, and take ownership and responsibility for outcomes: delivering high-impact improvements to source control, CI/CD, observability, and the secure foundations our trading platforms rely on in a fast-changing, cutting-edge environment.
