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.

### What You'll Do

• 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.
• Surface the right information by integrating with Kubernetes APIs, GitOps controllers, and gRPC/cRPC backends.
• 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.
• Write maintainable, well-structured frontend code and champion code quality across the product.

### What We're Looking For

Required

• 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 declarati...
