## 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.

- 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.**
