Founding Full-Stack Engineer - (AI Automation Platform)
$120,000 - $200,000 + 0.5-2% Equity + Benefits + Flexible PTO
San Francisco, CA (On‑Site)

Are you a full-stack engineer who wants to build and own the entire product stack powering an AI platform used by Fortune 500 companies, transforming manual compliance workflows into automated intelligence, whilst benefiting from full autonomy and founding‑level equity? This is a rare opportunity to join a YC‑backed, fast‑growing AI startup tackling a multi‑billion dollar market historically dominated by manual processes and consulting firms.

The team is building an AI agent platform that replaces expensive, time‑intensive compliance workflows with autonomous systems that handle data collection, testing, and documentation. Every output is auditable, verifiable, and delivered at scales and speeds impossible with traditional manual processes.

You will own the end‑to‑end development of the platform, building everything from database models and API endpoints to polished UI components for enterprise teams. You will build APIs that integrate tightly with AI agents, design review interfaces for AI‑generated outputs, architect scalable full‑stack services, craft intuitive interfaces that require no training, and continuously improve the platform by applying lessons learned from each project.

You'll report directly to the founding team and operate as a key owner across the entire stack—frontend architecture, backend services, AI agent orchestration, and production infrastructure. Expect deep technical responsibility, product influence, and the chance to build fundamental systems that will define how enterprise compliance workflows are executed.
