Senior Platform Engineer

Senior Platform Engineer | London, 3x Days - Monument

Ever wanted to build the kind of platform where every decision you make shapes how trading systems perform in real time?

You'd be joining a specialist engineering team in the midst of a major transformation, shifting from traditional infrastructure to a modern, cloud-driven platform built on AWS, Kubernetes, designed for scale and reliability in a critical trading environment.

Your focus will be AWS, EKS/ECS, Linux, and CI/CD. You will design and run container platforms, build and refine pipelines, and develop systems that support deployment, scaling, and platform health.

The pivot now is on maturing the platform: improving cluster design, tightening infrastructure patterns, reducing manual processes, and ensuring systems behave consistently across regions.

You will have ownership of decisions that directly influence how trading systems run day to day.

The work is hands-on, focused on engineering outcomes, and linked to real operational requirements of live markets.

• 3x Days in Monument, London
• £140,000 + Bonus

If you want to shape a cloud platform used across global trading and take responsibility for key technical decisions, this role offers that opportunity.

No up-to-date CV is required; we can work on updating it together if needed.
