Fullstack Engineer - Cofounder

The role

You will perform end-to-end product work across the agent experience including flows, integrations, and UI/UX. You will ship features across the stack and improve performance, reliability, and cost.

What you will do

• End-to-end product work across the agent experience
• Create, edit, and manage flows, run criteria, execution reliability, and observability
• Add new integrations and deepen existing ones
• Work on novel ways of building human-agent interactions
• Ship features across the stack with a tight feedback loop from real users
• Improve performance, reliability, and cost across agent runs and flow execution
• Build instrumentation, analytics, and developer tooling
• Maintain a high bar for code quality, tests, observability, and documentation

Required qualifications

• 4+ years building and shipping user-facing products end to end
• Frontend: React/Next.js (or equivalent), TypeScript
• Component-driven development
• Performance profiling
• Accessibility
• Data fetching/state
• Optimistic UI and cache invalidation
• Backend: Python FastAPI, background workers/queues, webhooks, Postgres (or similar) schema design, transactions, migrations
• Solid testing and observability habits (unit/integration tests, metrics, traces, structured logs)
• Bias to ship: scope thin slices, deliver quickly, instrument, iterate

Nice to have

• Event-driven architectures
• WebSockets/real-time UIs
• LLM/agent experience: tool-use patterns, prompt hygiene, guardrails, evaluation
• Infra familiarity (Vercel/AWS/Modal/Supabase/Redis Cloud or equivalent), CI/CD, feature flags
