Senior Software 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 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. The product is still early. You will be joining as our third engineer, working directly with the founders and early team to turn customer insights into fast, reliable, and scalable software. We are a well-funded, tight-knit team based in San Francisco. You will be building at the intersection of AI and marketplaces, of spreadsheets and real people. It is a unique opportunity to own major parts of the stack, shape the technical foundation, and help set the culture for how we build.
