Founding Software Engineer
About The Position
OuterSignal is building the customer intelligence layer for commerce. Brands know when an order comes in, but they only see ~5% of the real story. We show them the other 95%: not just who bought, but who that person is - the execs, influencers, journalists, retail buyers, investors, and everyday customers who become a brand’s best evangelists. Our platform enriches every order in real time with professional + personal signals, unlocks personas, and powers everything from surprise-and-delight outreach to smarter email flows, analytics, and BD leads. We serve 150+ brands and are growing 50% month-over-month - all within our first 6 months of operation. We're a small, high-performing team building the category-defining platform for e-commerce customer intelligence, backed by a world-class investor base.
