Senior Software Engineer

Senior Software Engineer 🚀 About Borderless Borderless is simplifying the complexity of global immigration, starting with the UK. Immigration is one of the most important - and most broken - systems in the global economy. It’s shaped human history, yet businesses and individuals hit friction at every turn, and government policy lurches with the political cycle. Our vision is simple: a world where borders are no longer barriers, empowering the ambitious, wherever they are. Backed by Entrepreneur First and Backed.VC , we’re already supporting 600+ businesses, 15,000+ workers and scaling fast into new sectors and markets.
