Senior Radio Frequency Engineer II
The Association of Technology, Management and Applied Engineering, Seattle, WA, United States
Senior RF Engineer II - Wireless & Connectivity Center of Excellence (CoE)
Location: On‑site 4 days per week at one of our US hubs (Scottsdale, Boston, San Francisco, Atlanta, or Seattle).
YOUR IMPACT
As a Senior RF Engineer II you will lead the design and development of advanced wireless connectivity solutions across Axon’s product portfolio, including Body‑Worn Cameras, in‑vehicle systems, wearables, and other next‑generation platforms. You will own RF architecture and implementation across a broad range of wireless technologies—Wi‑Fi, Bluetooth, LTE, 5G, GNSS—and will deliver robust, high‑performance designs that meet the demanding reliability and coexistence requirements of real‑world public safety environments.
What You’ll Do
Lead the RF design and integration of high‑performance wireless subsystems for portable and vehicular products (drones, automotive‑mounted systems, mobile devices, action cameras).
Contribute to the design and optimization of chip‑down RF circuitry and modules for LTE, 5G, GNSS, Wi‑Fi, and Bluetooth, ensuring robust performance across complex multi‑radio systems.
Own the RF system architecture and execution from concept through mass production, collaborating with electrical, mechanical, and software engineering teams.
Partner with antenna engineers to select, evaluate, and integrate antenna solutions—printed, PCB, or metal‑into high‑density product designs.
Conduct RF system debugging, interference mitigation, and receiver desense analysis to optimize real‑world performance.
Drive PCB layout for RF integrity, perform detailed layout reviews, and recommend design changes for optimal wireless performance.
Oversee technical deliverables from design partners, manage schedules, and ensure engineering quality throughout the product lifecycle.
Characterize, test, and validate RF performance using lab equipment such as spectrum analyzers, network analyzers, radio testers, and RF chambers.
Conduct real‑world RF field testing to validate wireless performance, capture KPIs, and troubleshoot connectivity issues.
Translate product‑level wireless performance requirements into actionable RF specifications and test plans.
Mentor junior engineers and contribute to building internal RF engineering best practices.
What You’ll Bring
Minimum bachelor’s degree in Electrical Engineering or related discipline.
9‑12+ years designing, integrating, and optimizing wireless RF solutions for battery‑powered and vehicular embedded products.
5+ years designing and integrating chip‑down cellular RF circuits (e.g., LTE, 5G, Cat‑4 and above).
Demonstrated expertise in multi‑transceiver wireless system architecture, RF circuit design, and system integration across 4G, 5G, multi‑band Wi‑Fi, Bluetooth, GNSS.
Proven experience as a Lead embedded RF Engineer, driving RF architecture, schematic design, integration, debug, and validation from concept through mass production.
Proficiency in providing technical oversight of RF design partners, including design reviews and day‑to‑day technical interactions.
Strong cross‑functional system‑level understanding of integrating multiple RF transceivers within complex, high‑density mobile, wearable, and vehicular embedded systems.
Experience with RF debugging, interference analysis, coexistence challenges, and receiver de‑sense mitigation.
Hands‑on proficiency with RF measurement equipment, characterization and test methodologies, and evaluation criteria for robust wireless performance.
Strong schematic design experience, preferably using Cadence or OrCAD.
Experience guiding PCB layout for wireless designs, performing layout reviews, and issuing design recommendations.
Solid understanding of antenna theory, structures, selection trade‑offs, and performance requirements in constrained embedded platforms.
Familiarity with industry standards and regulatory certification processes (3GPP, PTCRB, GCF, FCC, ETSI).
Experience operating within global, cross‑functional engineering teams, including mentoring and technical guidance of junior engineers.
Strong documentation, communication, and technical presentation skills.
Preferred Experience
Familiarity with Qualcomm RF chipsets and diagnostic tools (QXDM, QRCT, QCAT).
Experience with antenna design and integration, including PCB, printed, or metal antenna implementations.
Experience using RF simulation and analysis tools to inform design trade‑offs, performance prediction, and optimization.
Benefits that Benefit You
Competitive salary and 401(k) with employer match.
Discretionary paid time off.
Paid parental leave for all.
Medical, Dental, Vision plans.
Fitness Programs.
Emotional & Mental Wellness support.
Learning & Development programs.
Snacks in our offices.
Some roles may also require legal eligibility to work in a firearms environment.
We are an equal opportunity employer that promotes justice, advances equity, values diversity and fosters inclusion. We are committed to hiring the best talent—regardless of race, creed, color, ancestry, religion, sex (including pregnancy), national origin, sexual orientation, age, citizenship status, marital status, disability, gender identity, genetic information, veteran status, or any other characteristic protected by applicable laws, regulations and ordinances.
