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.

Axon 911 brings together Prepared and Carbyne under Axon. Together, we are creating the only platform that combines modern 911 infrastructure with an AI intelligence layer—helping public safety agencies move faster, make better decisions, and deliver better outcomes in the moments that matter most.

911 is the backbone of public safety, yet the professionals behind it have long been held back by outdated technology. Axon 911 is here to change that. Joining this team means more than taking a job—it means helping shape the future of emergency response and building a safer, more connected world.

We are seeking a Senior Electrical Engineer specializing in radio hardware and chip-down design to own the architecture, integration, development, and validation of sophisticated multi-radio systems for mission-critical connected hardware.

As a founding member of our hardware team, you will help define how multiple wireless technologies coexist within highly integrated, battery-powered devices. You will own critical radio hardware decisions from chipset and component selection through schematic design, PCB implementation, bring-up, RF validation, certification, and mass production.

You will solve complex challenges across Land Mobile Radio (LMR), LTE/cellular, broadband wireless, RF coexistence, interference, isolation, EMI/EMC, power, and antenna integration, working closely with RF, Systems, Mechanical, Firmware, and Manufacturing teams.

• Radio & Chip-Down Design: Own board-level implementation and integration of radio chipsets and associated circuitry across LMR, LTE/cellular, and broadband wireless technologies.
• Radio Architecture: Translate system and product requirements into radio hardware architectures, evaluating chipsets, transceivers, front-end components, interfaces, power requirements, and system-level tradeoffs.
• Schematic & PCB Implementation: Develop and review schematics and PCB implementations for RF transceivers, modems, front-end components, power circuitry, control interfaces, and supporting digital electronics.
• RF Integration & Coexistence: Design and validate multi-radio systems, addressing coexistence, desense, interference, isolation, harmonics, spurious emissions, grounding, shielding, and EMI/EMC.
• LMR & Cellular Integration: Solve hardware challenges associated with integrating regulated LMR frequencies alongside cellular and other wireless technologies within compact devices.
• Antenna & Mechanical Integration: Partner with RF, Antenna, Mechanical, and Industrial Design teams on antenna placement, RF routing, shielding, grounding, board layout, and enclosure-related RF performance.
• Bring-Up & Debugging: Lead radio hardware bring-up, characterization, and root-cause analysis using spectrum analyzers, oscilloscopes, network analyzers, signal generators, power meters, and related RF test equipment.
• Certification & Production: Drive radio hardware through verification, regulatory and carrier certification, SP/EVT/DVT/PVT, manufacturing ramp, and mass…
