SUPERNAL IS BUILDING THE OPERATING SYSTEM FOR BUSINESSES POWERED BY AI EMPLOYEES.

AI employees are here — and they’re redefining how businesses operate. At Supernal, we turn any tedious, manual process into an AI-powered workflow, managed through a delightful interface and accessible from web to phone. Businesses can now scale faster with smaller human teams empowered by large teams of AI employees.

We believe this is a trillion-dollar opportunity. As a founding engineer, you'll help invent the infrastructure and interfaces that make it possible. Supernal has already reached multi-million dollar revenue within months, and we’re just getting started.


WHY THIS ROLE EXISTS

We’re looking for a well-rounded, full-stack founding engineer to help us build robust AI systems and product experiences end-to-end. You’ll work directly with the founders on everything from core architecture to shipping new AI-powered features. If you’re a systems thinker, rapid builder, and care deeply about great UX and AI performance — we’d love to meet you.

- Obsessed with AI agents, LLMs, and building delightful automations

- Comfortable wearing many hats: engineer, product thinker, debugger, owner

- Thrive in fast-moving environments with a high degree of autonomy

- A natural builder: you ship, you own, you iterate
