Overview:
We’re looking for a Principal Software Engineer - Tech Lead(Army) to steer our technical direction and inspire a team of skilled developers. You’ll lead a high-performing development team to craft front-end applications and design business logic that integrates seamlessly with RFID hardware. But this isn’t just about building stuff in a vacuum, it’s about getting hands-on with customers, collaborating to solve bespoke challenges, and creating solutions that directly impact DoD missions.
This role is equal parts strategic thinker, technical collaborator, and product evangelist. If you thrive in ambiguity, love building something from the ground up, and want to make a tangible difference, we want you.
Who We Are
We’re not here to maintain the status quo, we’re here to rewrite it and innovate at the pace of need. Our team is laser-focused on creating cutting-edge RFID solutions for the DoD that bring passive and active RFID tech to life, solving tough integration challenges across global sites. We're a no-bench, get-after-it kind of company where initiative is rewarded, and innovation is our default setting. If you’re ready to dive in, take ownership, and ship real value, keep reading.
