Senior Platform Engineer

Build and operate the core infrastructure behind a container application platform. The work spans a microVM runtime, Kubernetes-based services, networking, data storage, and the tooling used to provision and observe production systems. You'll collaborate with teams responsible for the command-line interface and web console to make platform capabilities available to users.

• Design and operate the Kata Containers microVM runtime used to isolate workloads.
• Build and maintain Go services for platform control, scheduling, and ingress.
• Improve metrics, logging, alerting, and the broader observability pipeline.
• Contribute to CI/CD and provisioning systems, including Git Ops workflows and k3s.
• Coordinate with CLI and console teams to expose infrastructure capabilities.

• Strong systems programming experience;
  Go is preferred, with Rust also relevant.
• Hands-on knowledge of Kubernetes internals, such as controllers, custom resources, and admission webhooks.
• Ability to operate Linux at a low level, including understanding cgroups, name spaces, and networking.
• Experience with hypervisors or container runtimes such as KVM, containerd, runc, or Kata.
• A track record of delivering production infrastructure.

• Familiarity with eBPF or Cilium.
• Production PostgreSQL operations, including replication, backups, or failover, or experience running Prometheus-compatible metrics at scale.
• Contributions to open-source infrastructure projects.

• Full-time and remote within UK or EU time zones.
• The source describes equity, a home-office hardware budget, and an async-first, low-meeting culture.
