Former Founders

About the role Lumari is building autonomous AI agents that run supply chain procurement and execution, and we want ex-founders who've shipped product, closed deals, and know what it takes to build something from nothing. If you've lived the founder life and want to do it again with real backing, this is it. We work hard and move fast. We're part of YC X25 and well-funded. You'll have the resources and support you didn't have last time. We don't care about titles or what box your experience fits into. We care that you're sharp, relentless, and operate with full ownership. Product, eng, ops, GTM -- if you've built a company, you know how to figure it out. Why Join: Founder DNA: We hire people who default to action, make decisions with incomplete info, and don't wait to be told what to do. Ground Floor: We're early. You'll shape the company, the product, and the culture. Real Impact, Real Speed: Your work ships fast and moves the needle immediately. No layers, no politics.
