• Experience with RF front-end and antenna design for compact products, including antenna selection or design, multiband impedance matching, placement, keepouts, and RF PCB layout.
• Knowledge of low-EMI hardware design, including stackup, grounding, return paths, filtering, shielding, and high-speed and switching-supply layout practices.
• Experience diagnosing and fixing receiver desense from platform noise or collocated radios, with quantified sensitivity loss before and after fixes.
• Experience root-causing radiated and conducted emissions and immunity failures using near-field probes, current probes, and spectrum analysis.
• Experience with electromagnetic simulation using Ansys HFSS, SIwave, or equivalent tools.
• Working knowledge of FCC, ISED, and CE/RED requirements and experience writing RF and EMC test plans.
• Understanding of cellular, Wi-Fi, Bluetooth, and sub-GHz protocol stacks and their impact on RF testing and coexistence; expert use of VNAs, spectrum analyzers, signal generators, communication testers, and anechoic-chamber OTA systems.
• Ability to explain trade-offs clearly to hardware, mechanical, firmware, and program teams; mentoring experience or willingness to mentor junior engineers.
• New applicants must not require employment-authorization sponsorship or other immigration-related support.

Nice to have
