Platform Engineer

Principal Platform Engineer | AWS | Kubernetes | GitOps - City of London - Hybrid (2 days in the office)

Salary: £110,000 - £140,000

For engineers who want to shape the platform — not just run it.

We’re working with a well-funded UK fintech entering an exciting phase of commercial growth, and we’re looking for a Principal Platform Engineer to help define what comes next.

This is a genuine hands-on technical leadership role. You’ll have the autonomy to challenge the existing platform, make architectural decisions, build better patterns and raise the engineering bar.

The stack:

• AWS
• EKS
• Kubernetes
• Terraform
• Argo CD
• GitHub Actions
• Helm
• Grafana
• VictoriaMetrics

You’ll be tackling:

• Platform architecture and technical direction
• Kubernetes and cloud hardening
• GitOps and deployment automation
• Security, resilience and disaster recovery
• Observability and production readiness
• Repeatable customer environment provisioning
• Mentoring engineers and establishing engineering standards
• We’re looking for someone with deep production experience across AWS and Kubernetes , strong engineering judgement and a track record of building platforms that are secure, resilient and scalable.
• Fintech, regulated environments or SaaS experience is a strong plus.

It’s an opportunity to get your hands on the platform, influence the technology and help build the foundations of a growing financial technology business.
