About us We build technology that helps first responders save lives. Our mobile app puts critical clinical protocols and AI-powered guidance directly in the hands of paramedics and EMS crews in the field - the people who show up on the worst day of someone's life and have seconds to make the right call. When our app works well, it helps a medic make a faster, better decision at a patient's side. That's the kind of work you'll be doing here, and it matters. Where we are right now We're a growing company at an important turning point. Up to now we've outsourced our development overseas, and while that got us this far, we've decided it's time to bring everything in-house and build a real, full-time, U.S.-based team. This new development team will join our established IT company - so you'll be part of a bigger, stable organization, not a startup of one. As a small, rural-based company, our rates run leaner than big-city firms - but you get steady, long-term work, a low-ego team, and a direct line to a founder who values you. We want developers who are close to the work, invested in the product, and here for the long haul. This is a rare chance to get in early and help shape that team from the ground up - with a technical founder (a hands-on technologist, though not a developer myself) who genuinely values good engineers and keeps a friendly, low-ego environment. The role We're looking for one exceptional developer to own our Flutter mobile app and its Laravel/MySQL backend. You'll work from home day to day, but you'll be a true member of the team - not a faceless contractor.
