Platform Engineer (Kubernetes)

Platform Engineer (Kubernetes) On behalf of our client

• San Francisco, CA, on-site
• Full-time The build: Our client is building a Kubernetes platform that abstracts the complexity away while keeping the power. You'll work with the founding team to design systems, GitOps workflows, and the infrastructure layer that makes multi-cluster management feel intuitive for developers. Early team — your architecture patterns become the platform.

What you'll do

Build and extend the Kubernetes platform core features in Go, including custom operators and controllers. Design and implement GitOps workflows with ArgoCD to streamline continuous deployment. Develop infrastructure-as-code patterns with Terraform and Helm to provision and manage clusters. Work on distributed storage with Ceph and WEKA for high-performance, scalable storage.

Create observability and monitoring with Prometheus and Grafana to surface cluster health and performance. Build and optimize container networking with Cilium for security and observability. Design and implement federated Kubernetes architectures for multi-cluster management. Build automation tooling to cut operational overhead for developers running production workloads.

Contribute to open source components and establish platform architecture patterns as an early team member.

Requirements

What we're looking for

2+ years of software development experience. Proficiency in Go and Kubernetes, with hands-on experience building developer tools or infrastructure products. Experience with distributed storage such as Ceph and WEKA. Proficiency with ArgoCD and experience with CI/CD pipelines and automation workflows. Experience with Terraform, Helm, and related infra provisioning tools; familiarity with Ansible or Kubespray is a plus.

Background with service mesh (Istio or Linkerd) or CNI plugins. Experience with cloud platforms (AWS, GCP, Azure) and their managed Kubernetes offerings. Strong foundational software development skills and a willingness to learn. Contributions to Kubernetes ecosystem tools or similar open source projects. Experience with containerization, networking, and cloud-native architectures.

Logistics: San Francisco, CA, on-site.
