This high-intensity role involves building real AI components that directly drive multi-million dollar enterprise contracts.

Location

Why this role is remarkable

• Join a high-growth YC S23 startup that recently closed a $15M Series A, 5x'd its ARR in the last year, and is growing 20% month-over-month.
• Work in a purely engineer-driven culture where the founders are developers and the team consists of former founders who prioritize technical excellence and rapid shipping.
• Experience massive impact where your code is demoed to 20,000 sales reps or serves as the primary reason a customer signs an $800k contract.

What You Will Do

• Build and deploy full-stack applications and agentic systems across the stack using Next.js/React, Node.js/NestJS, PostgreSQL, MongoDB, and TypeScript.

The ideal candidate

• Possesses deep full-stack capability within a modern TypeScript environment and has a proven track record of shipping production-grade code to enterprise users.
• Brings previous early-stage startup experience or a founder's mentality, having built something from zero or deliberately chosen high-growth, high-stakes environments.
• Demonstrates practical experience building with AI/LLM APIs and agent frameworks, moving beyond theoretical knowledge to deliver functional, value-driving product features.
