Senior Firmware Engineer I

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.

Contribute to AIoT Device-level Firmware Infrastructure as part of the Platform Firmware development team and advance Axon’s mission to Protect Life. Platform Firmware supports all of Axon’s Camera-based products, key ownership of the Cellular LTE Link, Automated Test Systems for organizational Engineering Excellence, and is always at the fore-front of Innovation with Hardware Engineering for new programs. Firmware development environments primarily include Embedded Linux (C, C++, Golang, Yocto) and RTOS on Microcontrollers (C). Rust is being explored. Solve very challenging Firmware problems while applying Data Structure and Object Oriented thinking to build infrastructure APIs used by Axon’s Embedded Product teams.

The Platform Firmware team is hiring because there are career-defining, new innovative product-line programs being started in 2024 and 2025. These new programs synthesize all of Axon’s technologies and core competencies into what will be revolutionary offerings for our Customers. New team(s) are being built-out with a bias towards Central-Eastern USA to overlap with our teams in Western Europe. In addition, there is always innovative new work to be done on everything the Platform Firmware team supports.

Location: Working from home, from Seattle or Scottsdale
Travel: Firmware Engineering requires collaboration with Hardware Engineering and being hands-on. While the job is remote from Seattle (or Scottsdale), travel obligations to the office for Board Bring-up, Hardware and Manufacturing Support are required during critical build milestones of the Product Development Life-Cycle. We are forecasting 10% travel to Scottsdale, Brussels or Finland over a period of 18mo - remainder of time is discretionary to your choice of working from home or working from the office.
