Founding Software Engineer — First Hire

We’re building an AI-native ERP, with a team of ex-Microsoft, Apple, Wayfair, Columbia University, and Northeastern University, with published research in the space. Curently at multiple six figures in ARR and backed by top investors after just a few months of creation.

You will get a good salary and a lot of equity of a to-be unicorn.

We care deeply about talent density, and you’ll be our first hire. You’ll work directly with the founders, write a lot of code, talk to customers, make important product decisions, and help define the company’s engineering culture.

What you’ll do
Own products end-to-end across frontend, backend, data, infrastructure, and AI.
Turn difficult operational problems into simple, reliable software.
Ship quickly while maintaining a high bar for correctness.




Work directly with customers and iterate based on real usage.
Help establish how we build, hire, and operate as the company scales.

Exceptionally smart, dedicated, ambitious, and eager to grow with the company.
A strong full-stack engineer with experience in Python, React, TypeScript, APIs, and databases.
