Job description

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.
