🧡📦💙Founded in 2012, EasyPost is a YC unicorn whose mission is to make shipping simple for businesses—from garage startups to the Fortune 500. Shipping, now more than ever, is the backbone of the global economy, but integrating the technology-enabled operations of a modern business with the low-tech and complex shipping industry has always been a challenge. EasyPost solves this problem with the first developer-friendly REST API for shipping, and we continue to push boundaries and discover new ways to simplify shipping for all. Our team is rapidly growing, and this is the perfect time to get on board. Join us and help build the shipping infrastructure of the future. We’re builders, problem-solvers, and “there has to be a better way” people. We like elegant architecture, fast decisions, and shipping (pun intended) improvements that power millions of deliveries every day. We stay scrappy, we move fast, and we don’t wait for permission to innovate in an industry that desperately needs it. If you want to work on systems that actually move the world—literally—you’re in the right place. 🚚✨
