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 declarative infrastructure/continuous deployment patterns. * Proficiency with observability tooling — Prometheus and Grafana for surfacing cluster health and performance. * 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. **Nice to Have** * Policy\-as\-code and security tooling for Kubernetes. * Background in systems programming or distributed systems. * Experience with cloud platforms (AWS, GCP, Azure) and their managed Kubernetes offerings. * Track record shipping developer tools or infrastructure products. * Familiarity with analytics tools such as PostHog. ### **Location \& Work Arrangement** This role is **on\-site in San Francisco, CA**. Remote work is not available for this position. **Visa sponsorship is not available.** ### **Compensation \& Benefits** Competitive compensation commensurate with experience. Early\-team equity opportunity at a venture\-backed infrastructure startup.
