Product Engineer

Rejigg is redefining how small businesses change hands. Our AI-powered marketplace connects buyers and sellers, automates diligence, and simplifies transactions, making entrepreneurship more accessible and ownership transitions radically easier.

The process today is fragmented, opaque, and full of middlemen. We are fixing that and it is working. Today, we work with tens of thousands of buyers, thousands of sellers, and are on pace to 10x year over year.

The code you write will directly power one of the biggest decisions in someone’s life: selling their legacy or stepping into ownership. It is emotional, it is complex, and it deserves care. Rejigg is still early. You will join a small engineering team working directly with the founders to turn customer insight into simple, fast, reliable product. This role is a great fit if you like owning problems end-to-end, sweating UX details, and shipping quickly with tight feedback loops.

We are a well‑funded, tight‑knit team based in San Francisco. You will be building at the intersection of AI and marketplaces, spreadsheets and real people. This is a chance to take real ownership, grow quickly, and help define how we build.
