Founding Engineer: Agentic OS (YC-backed)

About the Role

We're building an agentic operating system for the Enterprise and have achieved product-market fit with thousands of agents deployed across scale-up startups and enterprise companies. We're looking for someone who operates at CTO-level—someone who can take a vague problem, scope it, build it end-to-end, and ship something that provides real value.

This is a backend-heavy, AI-native role where you'll need to go full stack when required. No hand-holding. No waiting for specs. You need to be a full-stack engineer, an AI engineer, and a product engineer in one person.

What You'll Do

• Own large parts of the product end-to-end, from user insight to production

• Build and improve agentic systems to make them more accurate, reliable, and powerful

• Work at the frontier of AI engineering—context engineering, tool use, agent architectures

• Talk to users, understand their pain points, and scope features that solve real problems

• Push AI-first development practices and scale yourself through automation

• Review code quickly while maintaining high standards across the codebase

What We're Looking For

• A 100x engineer: razor sharp, able to solve difficult problems fast

• Deep product sense—you build for users, not for code's sake

• Strong Go backend experience with clean, maintainable code practices

• Experience building AI products, ideally agentic systems or AI coding tools

• Fascination with new coding paradigms (Claude Code, Cursor, coding agents)

• Ability to scale yourself to an extreme degree through automation

• Great code taste and ability to review PRs at speed without sacrificing quality

• Versatility: backend-heavy but not allergic to frontend (Vite/Typescript)

• Thrive in ambiguity—you don't need a PM to tell you what to build

• Track record of building something from scratch (startup, side project, shipped feature)

• Plus factors: AI research background, experience at an AI coding startup, former founder experience

Compensation & Details

• Generous equity and compensation reflecting the outsized impact of this role

• Unlimited AI budget—we practice what we preach

• Work alongside a brilliant design engineer and a CTO cofounder who will push your growth
