Frontend Engineer – Cluster OS Platform

About the role

A well-funded early-stage Kubernetes infrastructure company is hiring a Frontend Engineer to design and build the interface for their flagship OS-like platform — an experience that makes distributed systems approachable for both individual tinkerers and production engineering teams. You'll help define interaction patterns, visualizations, and real-time UIs that translate complex cluster state into clear, actionable experiences. This is a high-impact, early‑team role based on‑site in San Francisco.

Key responsibilities

• Own the cluster management user interface, including provisioning flows, natural language interfaces, and real-time proactive system insights.
• Design and build visualization systems that make distributed state legible at a glance.
• Integrate with Kubernetes APIs, GitOps controllers, and gRPC/cRPC backends to surface the right information.
• Build real‑time reactive UIs using Convex that scale from single users to large teams.
• Prototype new interaction patterns for infrastructure management, test assumptions quickly, and iterate based on feedback.
• Collaborate with backend and platform teams to design elegant protocols for the frontend.
• Establish frontend architecture patterns and best practices as an early engineering team member.

Required profile

• Strong frontend fundamentals with a track record shipping user‑facing infrastructure or developer tools.
• End‑to‑end experience building Next.js applications using React, Tailwind, and shadcn/ui.
• Experience or familiarity with Convex for real‑time/reactive UI patterns.
• Production Kubernetes experience – internals, CRDs, operators, cluster architecture, etcd backup/restore, and troubleshooting cluster health.
• Infrastructure‑as‑Code proficiency with Terraform and Helm.
• Deep GitOps experience with ArgoCD and declarative continuous‑deployment patterns.
• Proficiency with observability tooling – Prometheus and Grafana.
• Comfortable working with complex state management that reflects real‑world infrastructure.
• 5+ years working in production Kubernetes‑based infrastructure.
• Strong Go skills for building system‑level tooling, controllers, and distributed‑systems components.
