Senior Platform & SRE Engineer – Leading Global Hedge Fund – London

Company: Mondrian Alpha
Apply for the Senior Platform & SRE Engineer – Leading Global Hedge Fund – London
Location: London
Job Description:

We are partnering with a leading global investment organisation seeking a rare individual: someone who has built platforms – not merely operated them. This role sits at the intersection of platform engineering, SRE, and automation, serving a firm where software delivery reliability and velocity are mission-critical.

Their engineers run infrastructure where reliability directly affects business outcomes – measured, profiled, and continuously improved across live systems.

The Successful Engineer:

  • Build and own a self-service internal developer platform – engineers commit, everything else is automated.
  • Python background.
  • Design and standardise CI/CD pipelines and release frameworks adopted org-wide.
  • Run EKS clusters end-to-end: scaling, infra decisions, cost, reliability.
  • Own production – incidents, MTTR reduction, post-mortems, and fixes.
  • Drive a zero-touch DevEx: commit → test → deploy with no human gates.
  • Operate independently as a solo SRE across complex, high-scale systems.

The Toolkit:

  • AWS (deep), Kubernetes / EKS, Terraform or equivalent IaC.
  • CI/CD platform design: GitHub Actions, ArgoCD, Tekton, or similar — templated, not ad-hoc.
  • Observability: metrics, tracing, alerting – built-in, not bolted on.
  • Database ops: Aurora, PostgreSQL, SQL – practical, production-grade.
  • AI-assisted engineering a strong plus – uses tooling to improve delivery velocity.

Ideal Background:

  • Proven experience in fintech, trading, or other high-availability, scale-critical environments.
  • Has shipped a platform that other engineers use daily without thinking about it.
  • Talks in systems and patterns – not individual tasks.

The Environment:

This organisation operates on a flat structure – no committees, no bureaucracy. Engineering and business sit shoulder-to-shoulder. Infrastructure that’s faster and more reliable doesn’t just run better – it changes outcomes. If you believe platform engineering is a craft, and automation is the only truth – this is the environment you’ve been building toward.
