Frontend Engineer — Cluster OS

About The Role

We're a managed AI infrastructure company building a next-generation, OS-like experience that makes distributed Kubernetes-based systems approachable for both individual builders and production teams. We're looking for a Frontend Engineer to own and shape the interface of our cluster operating system — translating complex distributed state into clear, actionable, and beautiful user experiences. This is an early engineering team role with significant ownership.

What You'll Do

• Own the cluster OS user interface end-to-end, including provisioning flows, natural language interfaces, and real-time proactive system insights.
• Design and build visualization systems that make distributed cluster state legible at a glance.
• Integrate with Kubernetes APIs, GitOps controllers, and gRPC/cRPC backends to surface the right information at the right time.
• Build real-time reactive UIs using Convex that scale from solo users to large production teams.
• Prototype new interaction patterns for infrastructure management, iterate quickly based on feedback, and validate assumptions early.
• Collaborate with backend and platform teams to co-design frontend-friendly protocols and APIs.
• Establish frontend architecture patterns and best practices as a foundational team member.
• Write maintainable, well-structured code and champion frontend quality across the product.

What We're Looking For

• Required: 5+ years of production experience in a Kubernetes-based infrastructure environment.
• 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 CSS, and shadcn/ui.
• Solid knowledge of Kubernetes internals — CRDs, operators, cluster architecture, etcd backup/restore, and troubleshooting.
• Infrastructure as Code experience with Terraform and Helm.
• Deep familiarity with GitOps workflows using ArgoCD and declarative continuous deployment patterns.
• Strong proficiency in Go for system-level tooling, controllers, and distributed systems.
• Observability experience with Prometheus and Grafana for surfacing cluster health and performance.
• Comfortable working with complex state management that reflects real-world infrastructure.
• Experience with APIs and backend services; willingness to contribute to backend logic when needed.
• Strong communication skills, self-direction, and the ability to collaborate across product, design, and backend teams.

Nice to Have

• Experience with Convex for real-time/reactive UI patterns.
• 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.
• Experience creating visualization systems and compute-efficient UI animations.
• Familiarity with analytics tools such as PostHog.
• Track record shipping developer tools or infrastructure products.
