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
• A founding seat at the table where you'll shape the product and company direction
