Senior Principal Platform Engineer

What you'll do

Own the provisioning tool as a software product

• Develop and maintain our in-house automated cluster provisioning solution so every cluster is reproducible and consistent.
• Design new features, write tests, manage releases and versioning, and keep clear documentation for its users.
• Gather requirements from internal teams and turn them into a roadmap for the provisioning platform.
• Refactor and modernize the existing codebase over time, paying down technical debt while keeping clusters stable.
• Integrate the tool with CI/CD, observability, secrets management and access control.
• Build internal tools, services, APIs and CLIs in Go that automate deployment and operations.

Run on-prem Kubernetes for the whole company

• Deploy, maintain and upgrade on-prem Kubernetes clusters, including capacity planning, version upgrades and lifecycle management.
• Operate cluster-critical components: storage (Longhorn), networking (Calico or Cilium, MetalLB, ingress controllers) and internal registries (Harbor or similar).
• Build multi-tenancy so many teams can share clusters safely, using namespaces, RBAC, resource quotas, network policies and fair-share scheduling.
• Plan, run and regularly test backup, disaster recovery and etcd maintenance.

Manage the infrastructure underneath

• Manage bare-metal and virtualized infrastructure, working with data center and IT teams on hardware provisioning and replacement.
• Design and maintain infrastructure across on-prem data centers and AWS / Azure, using infrastructure-as-code (Terraform, Pulumi or similar) wherever possible.
• Implement observability for metrics, logging, tracing and alerting (Prometheus, Grafana, OpenTelemetry or similar).

Build security in

• Embed security and compliance into the platform: secrets management, IAM, policy-as-code and supply chain security.
• Patch OS and cluster components on a regular cadence to meet security and compliance requirements.

Work as a full member of the XP team

• Join planning, stand-ups and retrospectives, and pair with engineers on implementation every day.
