Senior Full-Stack Engineer

You will build the enterprise dashboard that teams use every day to manage keys, credits, guardrails, and spend analytics. The surface spans Next.js 16 App Router, Supabase RLS, TanStack Query, Tailwind v4, and the Rust gateway every request passes through. You will work across multi-tenancy, credit ledger integrity, and LLM request lifecycle — with a strong product instinct for what teams managing LLM infrastructure actually need.

What you'll do

• Ship dashboard features end-to-end — schema, API routes, UI, tests
• Design multi-tenant data access with Supabase Row Level Security
• Own the credit ledger (reserve + settle) integrity under concurrency
• Partner with design on data-dense, enterprise-grade interfaces
• Integrate Stripe billing, subscriptions, and credit purchase flows

Required experience

• 5+ years shipping production TypeScript / Next.js
• Strong SQL and Postgres fundamentals, comfortable writing RLS policies
• Experience with multi-tenant SaaS and authentication flows
• Track record of owning a product surface from concept to launch

Nice to have

• Experience with LLM APIs, prompt engineering, or AI infrastructure
• Stripe billing integration at scale
• Open-source contributions
