About The Position

Join Axon and be a Force for Good. At Axon, we’re on a mission to Protect Life. We’re explorers, pursuing society’s most critical safety and justice issues with our ecosystem of devices and cloud software. Like our products, we work better together. We connect with candor and care, seeking out diverse perspectives from our customers, communities and each other. Life at Axon is fast-paced, challenging and meaningful. Here, you’ll take ownership and drive real change. Constantly grow as you work hard for a mission that matters at a company where you matter. Your Impact We are developing the next generation of mission-critical communications systems to builds mission-critical devices used by public-safety professionals worldwide. As a Staff Wireless Software Engineer , you will be a technical leader driving architecture and implementation of wireless protocol stacks, transport abstraction layers, and real-time communication systems across our devices. You will operate at the intersection of RF, embedded systems, and cloud-connected software. This is a hands-on technical role with broad architectural influence. Work Location: This role is eligible to be based out of Axon's US hubs in Atlanta, Boston, Scottsdale (HQ), San Francisco, or Seattle, and follows a hybrid schedule. We rely on in-person collaboration and ask that team members work onsite 4 days per week, Tuesdays through Fridays , with the flexibility to work remotely on Mondays, unless there is an approved workplace accommodation. We believe that connection fuels innovation, and our in-office culture is designed to foster meaningful teamwork, mentorship, and shared success. This mission-critical wireless systems require both RF understanding and deep systems software expertise. This position sits at that boundary and defines the reliability and trust of the entire communications platform..
