Job description

Senior Software Engineer | Platform Engineering | Go, Kubernetes, GitOps | Global Software Company

Salary: £80,000 - £110,000 (depending on level of experience) plus bonus
Windsor: hybrid, 4 days a week on site

Our client is a global software company whose products run behind mission-critical systems in heavily regulated industries. This role is a senior, hands-on engineering seat on their platform team, where you'll write the Go software that automates a brand-new, cloud-agnostic Kubernetes platform. You'll build Kubernetes Operators and controllers from scratch, with provisioning, upgrades, scaling and recovery all handled in code, and design the APIs that hide the messy differences between clouds.

The platform is greenfield, nothing in production yet, and built to scale very wide, very fast. You'll mentor other engineers and set the standard for how this software gets built.

Non-Negotiables

Strong production Go
Java, C++ or Rust considered, Go preferred
8+ years in software or platform engineering
Distributed systems and failure handling
Production Kubernetes at scale
Automated testing, unit to cluster level
Cluster security, RBAC and secrets

What You'll Work With

Kubebuilder, Operator SDK and client-go
GitOps CI/CD with Argo CD or Flux
Helm and Terraform for Infrastructure as Code (IaC)
Multi-cloud across AWS, Azure and GCP plus private data centres
A fleet-orchestration platform managing clusters at scale
Observability with Prometheus, Grafana and Loki
Service mesh such as Istio, Linkerd or Cilium

Nice to Haves

Designing and versioning Kubernetes APIs for the long term
Operators for backup, restore or multi-resource orchestration
Managed Kubernetes platforms like Rancher, EKS, AKS or GKE
Policy-as-code, admission controllers and container scanning

Why Join / Projects

This is a rare greenfield build. The Kubernetes platform is being written from scratch to be completely cloud and data-centre agnostic. Product ships one container and it runs anywhere, on any public cloud or in the company's own data centres, with upgrades, patching, failover and disaster recovery all handled in the platform and invisible to the customer. You'll write the Operators and controllers that make that work.

It's a senior individual-contributor seat with real influence. You'll set engineering standards, mentor other engineers and shape technical direction alongside the Kubernetes architects and SRE teams, without carrying line management yourself. The platform is designed to scale very wide, very fast, as the team grows over the next couple of years.
