Fullstack Engineer - Frontend Focus

About Inference.net

Inference.net is a distributed inference platform that aggregates idle GPU capacity worldwide to serve large language models such as DeepSeek and Llama 4. With more than 5,000 GPUs and hundreds of terabytes of VRAM connected at any moment, we empower developers to run powerful models at planet‑scale. The team is small, well‑funded, and works primarily in downtown San Francisco (hybrid flexibility as needed). Investors include a16z CSX and Multicoin.

What You’ll Do

• Own the user experience – design, build, and polish dashboards, consoles, and customer‑facing apps that let users observe, configure, and pay for inference at scale.
• Ship end‑to‑end features – from Figma wireframe to React component to backend API and database migration.
• Design a component system in React + Tailwind that supports rapid iteration and a cohesive design language.
• Optimize performance – SSR, code‑splitting, hydration, and WebSocket‑driven real‑time updates that hold up under millions of requests per day.
• Collaborate across disciplines – work shoulder‑to‑shoulder with distributed‑systems engineers, product designers, and founders to turn complex infrastructure into delightful product.
• Level‑up the team – lead design reviews, mentor junior engineers, and introduce best practices for testing, accessibility, and observability.

What We’re Looking For

Must‑Have

• 5+ years building production React applications
• Deep knowledge of Tailwind CSS & modern CSS architecture
• Typescript mastery and strong fundamentals in JS/DOM/APIs
• Experience designing REST/JSON or gRPC backends (Node, Go, or similar)
• AuthN/AuthZ design (OIDC, JWT)
• Product sense: you care about UX details & accessibility

Nice‑to‑Have

• Experience with Tanstack / Next.js
• Data‑viz libraries (Recharts, Visx, D3)
• tRPC experience
• Familiarity with GPU or ML tooling dashboards
• Comfort debugging performance issues (Lighthouse, Chrome DevTools)
• Dev‑ops chops: CI/CD, Docker, Terraform

Compensation

• Base salary: $120,000 – $180,000
• Equity: significant early‑stage grant
• Benefits: full medical/dental/vision, 401(k) with match, generous PTO, commuter + hardware stipends, daily office lunch

How We Work

We iterate fast, test in prod (safely!), and celebrate small wins. You’ll demo work twice a week, pair with systems engineers, and ship to users continuously. Most of us are in the office 3–4 days a week; remote candidates considered if time‑zone compatible with Pacific hours.
