Senior Platform Engineer / SRE

London | Hybrid Myn is recruiting for a leading financial technology organisation in London and is looking for an experienced Platform Engineer / Site Reliability Engineer to help build and operate highly available, large-scale technology platforms.

This is a hands-on engineering position sitting across cloud infrastructure, platform engineering, automation, observability and reliability.

Rather than traditional infrastructure support, the focus is on engineering platforms and tooling that make applications easier to deploy, operate and scale while improving reliability across production environments.

The role

You’ll work closely with software, platform and data engineering teams to improve cloud infrastructure and production reliability.

Your work could include designing cloud infrastructure, building deployment automation, improving observability, defining reliability standards and helping engineering teams understand how their services behave in production.

You’ll also contribute to incident investigation and use what is learned from production issues to engineer more resilient systems.

What we’re looking for

  • Strong AWS and/or Google Cloud Platform experience
  • Kubernetes and containerised environments
  • Terraform / Infrastructure as Code
  • CI/CD and deployment automation
  • Observability, monitoring and distributed tracing
  • Experience with production incident response and root-cause analysis
  • Cloud networking, IAM and security principles
  • Understanding of highly available and distributed systems
  • Strong automation mindset

Experience with technologies such as OpenTelemetry, Datadog, Grafana, GitLab CI, Backstage, Python or Java would be advantageous.

Knowledge of SLOs, SLIs, error budgets, automated remediation or chaos engineering would be particularly interesting.

We’re especially keen to hear from engineers who have worked on high-throughput or mission-critical platforms where reliability and performance have a direct impact on customers.

Location: London

Working pattern: Hybrid

If you enjoy solving complex platform and production engineering problems rather than simply maintaining infrastructure, we’d like to hear from you.
