What are the responsibilities and job description for the Founding Engineer: Agentic OS (YC-backed) position at Clera?
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
