Founding Engineer

ABOUT THE ROLE

This is a founding engineering role at a YC-backed (Seed stage) enterprise AI company building the agentic operating system for businesses. The platform enables companies to deploy, orchestrate, and manage AI agents at scale — automating complex workflows across hundreds of integrations without requiring deep engineering expertise from end users. The company has strong early traction, with thousands of agents deployed across scale-up and enterprise customers, and is growing rapidly.

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 creates real user value — with no hand-holding and no waiting for specs. You are a full-stack engineer, an AI engineer, and a product engineer in one person. Being a former founder is a genuine plus.

US work authorization is required. Visa sponsorship is not available.

WHAT YOU'LL DO

• Own large parts of the product end-to-end — from user insight all the way to production

• Build and continuously improve agentic systems: accuracy, reliability, and capability

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

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

• Ship full-stack when needed — Go backend and Vite/TypeScript frontend

• Champion AI-first development practices: coding agents, automation, and relentless self-scaling

• Review code fast and maintain high standards across the codebase

WHAT WE'RE LOOKING FOR

Required

• Ability to own features end-to-end from ideation to production with minimal direction

• Hands-on experience designing and deploying AI-driven systems — agent architectures, context engineering, and tool use

• Track record of ensuring production readiness: monitoring, observability, performance tuning, and reliability

• Strong product sense with a demonstrated history of building for user outcomes

• Love of Go and a commitment to clean, maintainable code

• Comfort with ambiguity — you identify what needs to be built without being told

• Versatility: backend-heavy but not allergic to frontend work

• Prior experience building something from scratch — a startup, a meaningful side project, or a zero-to-one feature

Nice to Have

• AI research background

• Experience at an AI coding or developer tooling startup

• Prior founding or co-founding experience

• Familiarity with modern AI-assisted development tooling (e.g. Claude Code, Cursor, coding agents)

Tech Stack

• Backend: Go

• Frontend: TypeScript, Vite

• AI Models: Multi-model environment (OpenAI GPT, Anthropic Claude, Google Gemini)

COMPENSATION & BENEFITS

• Salary: $120,000 – $250,000 USD annually, reflecting the outsized impact of this role

• Generous equity package — this is a founding-level seat

• Unlimited AI tooling budget — the team practices what it preaches

• Direct collaboration with a world-class design engineer and a technical co-founder/CTO committed to your growth

• A true seat at the table: you will shape the product and the company
