Senior Radio Frequency Engineer

Axon•Scottsdale, AZ

About The Position

As a Senior RF Engineer I at Axon, you will lead RF design and integration for assigned products and wireless subsystems, potentially including in-vehicle systems, Body Worn Cameras, wearables, and next-generation platforms. You will contribute to RF architecture decisions and independently own implementation, integration, validation, and debugging of RF subsystems—from wireless modules to chip-down designs—through design release and production readiness. Work includes RF circuit design, RF PCB layout guidance and review, RF routing, impedance-matching networks, antenna-feed integration, and hands-on validation. The role applies expertise in LTE, 5G, Wi-Fi, Bluetooth, GNSS, and related wireless technologies to optimize mission-critical video and communications products. You will address complex multi-component and inter-subsystem RF challenges while balancing wireless performance, coexistence, antenna constraints, power, manufacturability, reliability, cost, schedule, and regulatory requirements. You will collaborate with industrial design, electrical, firmware, mechanical, manufacturing, quality, and regulatory teams, communicate RF tradeoffs and validation results, and provide technical guidance to junior engineers and design partners. The position contributes to products intended to enhance public safety, operational effectiveness, and community trust.
