Founding Engineer
Role summary
We are seeking a Founding Engineer to join a well-funded (raised $3M from YC and notable angels) startup building an agentic operating system for the enterprise. The company has achieved product-market fit and is experiencing rapid revenue growth. This role requires a highly versatile individual operating at a CTO level, capable of taking vague problems, scoping, building end-to-end, and delivering value with minimal supervision. The ideal candidate will be a full-stack, AI, and product engineer with a strong preference for backend development using Go, Vite, and Typescript. Experience with AI engineering, agentic systems, and a passion for AI-first development and automation are crucial. A background as a founder or in AI research/startups is a plus. This is a critical founding role with significant impact on the product and company direction.
We need someone who operates at CTO-level. Someone who can take a vague problem, scope it, build it end-to-end, and ship something that actually provides value. Backend-heavy, AI-native, but able to go full stack when needed. 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. Being a former founder is a plus for this role.
**The responsibilities:**
* Own large parts of the product end-to-end. From user insight to production
* Build and improve our agentic systems. Make them more accurate, more reliable, more powerful
* Work at the frontier of AI engineering. Context engineering, tool use, agent architectures
* Stack is Go Backend, Vite (Typescript) Frontend
* Talk to users. Understand their pain. Scope features that actually solve problems
* Push AI-first development. Claude Code, coding agents, automation. You should be obsessed with scaling yourself
* Review code fast. Maintain high standards across the codebase
**You are a good fit if you:**
* Are a 100x engineer. Razor sharp. Able to solve difficult problems fast
* Have deep product sense. You build for users, not for code's sake
* Love Go and care about clean, maintainable code
* Have experience building AI products, ideally agentic systems or AI coding tools
* Are fascinated by the new coding paradigms. Claude Code, Cursor, coding agents. You're already using them
* Know how to scale yourself to an insane degree through automation
* Have great code taste and can review PRs at speed without sacrificing quality
* Are versatile. Backend-heavy but not allergic to frontend
* Thrive in ambiguity. You don't need a PM to tell you what to build
* Have built something from scratch before. A startup, a side project, a feature that shipped
AI research background is a plus. Experience at an AI coding startup is a plus. But what matters most is that you're exceptional and hungry.
**What you get:**
* Work alongside a brilliant design engineer who makes everything look and feel incredible
* A CTO and cofounder who will push you harder than anyone has before and make you grow faster than you thought possible
* Unlimited AI budget. We practice what we preach
* Generous equity and comp reflecting the outsized impact this role will have
* A seat at the table. This is a founding role. You'll shape the product and the company
We're building the platform that redefines how people work. If you want to build at the frontier, reach out.
