Axon employees are empowered to report safety concerns as they arise and activities potentially impacting the environment.Your Impact Contribute to IoT device-level firmware with a primary emphasis on the Cellular link as part of the Platform Firmware team.

Platform Firmware owns connectivity across all camera-based products, drives automated test systems for engineering excellence, and partners with Hardware Engineering on new programs.

Development environments include Embedded Linux (C/C++, Go, Yocto) and RTOS on micro-controllers (C). Rust is being explored. You will solve challenging cellular-centric problems and craft code used across Axon embedded product team.

Where You’ll WorkLocation: Working Remotely with easy access to a Local Axon Hub in Scottsdale, AZ What You’ll Do Travel: Firmware Engineering requires collaboration with Hardware Engineering and being hands-on.

While the job is Remote near a Local Axon Hub, 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 Boston, 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.
