Job summary

Axon in the United States seeks a senior hardware engineer to own radio architecture for chip-down RF in compact, battery-powered devices spanning LMR, LTE, and broadband wireless.

You will lead bring-up, verification, and mass production, collaborating with RF, systems, mechanical, firmware, and manufacturing teams to ensure robust, compliant wireless designs. The role requires deep hands-on Cadence tool use and RF test equipment experience.

Qualifications

• Seven or more years of radio hardware or RF electronics design experience.
• Bachelor's degree in Electrical Engineering or a related discipline.
• Experience with chip-down radio design or board-level integration of wireless transceivers and modems.
• Strong experience with radio technologies such as LMR, LTE/cellular, broadband wireless, Wi-Fi, Bluetooth, or GNSS.
• Experience designing and debugging RF circuitry including transceivers, front ends, filtering, matching, switching, amplification, clocks, power delivery, and digital control interfaces.
• Deep understanding of RF coexistence, interference, desense, isolation, harmonics, spurious emissions, grounding, shielding, and EMI/EMC in compact multi-radio products.
• Hands-on schematic and PCB design using Cadence OrCAD and Allegro.

Responsibilities

• Own board-level implementation and integration of radio chipsets across LMR, LTE/cellular, and broadband wireless.
• Translate system and product requirements into radio hardware architectures and evaluate chipsets and components.
• Develop and review schematics and PCB implementations for RF transceivers and related electronics.
• Design and validate multi-radio coexistence, addressing desense, interference, isolation, and EMI/EMC.
• Solve hardware challenges integrating LMR with cellular and other wireless tech in compact devices.
• Partner with antenna, mechanical, and industrial design on RF routing and enclosure performance.
• Lead radio hardware bring-up, characterization, and root-cause analysis using RF test equipment.
• Drive designs through verification, regulatory and carrier certification, prototype and production builds.

Job description

Role overview

This is a senior hardware engineering role focused on chip-down RF and wireless design for compact, battery-powered devices that combine Land Mobile Radio, LTE/cellular, and broadband wireless technologies. The engineer will act as a founding member of a hardware team, owning radio architecture decisions end-to-end from chipset selection through mass production, and partnering across RF, systems, mechanical, firmware, and manufacturing disciplines.

Responsibilities

• Own board-level implementation and integration of radio chipsets and associated circuitry across LMR, LTE/cellular, and broadband wireless technologies.
• Translate system and product requirements into radio hardware architectures, evaluating chipsets, transceivers, front-end components, interfaces, and power tradeoffs.
• Develop and review schematics and PCB implementations for RF transceivers, modems, front-end components, power circuitry, control interfaces, and supporting digital electronics.
• Design and validate multi-radio coexistence, addressing desense, interference, isolation, harmonics, spurious emissions, grounding, shielding, and EMI/EMC.
• Solve hardware challenges associated with integrating regulated LMR frequencies alongside cellular and other wireless technologies inside compact devices.
• Partner with antenna, mechanical, and industrial design teams on placement, RF routing, shielding, grounding, board layout, and enclosure-related RF performance.
• Lead radio hardware bring-up, characterization, and root-cause analysis using spectrum analyzers, oscilloscopes, network analyzers, signal generators, and power meters.
• Drive designs through verification, regulatory and carrier certification, prototype and production builds, manufacturing ramp, and mass production.
• Provide technical direction on radio hardware architecture while working with chipset vendors, external design partners, ODMs/JDMs, and internal engineering teams.

Requirements

• Seven or more years of radio hardware or RF electronics design experience and a bachelor's degree in Electrical Engineering or a related discipline.
• Demonstrated experience with chip-down radio design or board-level integration of wireless transceivers and modems, beyond integrating pre-certified modules.
• Strong experience with one or more radio technologies such as LMR, LTE/cellular, broadband wireless, Wi-Fi, Bluetooth, or GNSS.
• Experience designing and debugging RF circuitry including transceivers, front ends, filtering, matching, switching, amplification, clocks, power delivery, and digital control interfaces.
• Deep understanding of RF coexistence, interference, desense, isolation, harmonics, spurious emissions, grounding, shielding, and EMI/EMC in compact multi-radio products.
• Hands-on schematic and PCB design experience using professional tools such as Cadence OrCAD and Allegro or comparable platforms.
• Strong hardware bring-up and debugging skills using spectrum analyzers, oscilloscopes, network analyzers, signal generators, and related RF test equipment.

Benefits and work setup

• Remote-eligible with relocation assistance available.
• Mission-driven environment focused on public safety technology, with emphasis on equity, inclusion, and accessibility in hiring.
• Some roles may require legal eligibility to work in a firearms environment.
