Founding Engineer: Agentic OS (YC-backed)

Clera

Job Description

Job Description

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
