RF Design Engineer

The role

This person will own antenna and RF hardware design to set deployment range, capacity, and sectorization geometry. They will take designs from EM simulation through fabrication, measurement, and production qualification.

What you will do

• Model patch, array, and air-gap antennas in HFSS or CST
• Take designs from simulation through fabrication, measurement, and qualification
• Design matching networks, harmonic filtering, and PA/LNA chains for sub-GHz and Wi-Fi radios
• Integrate Wi-Fi, HaLow, and other radios on shared platforms
• Own coexistence and isolation across co-located standards
• Own RF schematic and layout decisions including stack-up, controlled impedance, RF routing, and isolation
• Review PCB layouts with the EE team
• Characterize designs on VNA
• Run S-parameter and radiation pattern measurements
• Drive bring-up of new RF hardware

Required qualifications

• 3–5 years of RF hardware design experience on production wireless hardware
• Strong RF fundamentals: transmission lines, impedance matching, S-parameters, signal integrity
• EM simulation: HFSS, CST, or equivalent
• Hands-on RF measurement: VNA, S-parameter, and pattern or gain measurement
• PCB-level RF design experience: stack-up, controlled impedance, RF routing, isolation
• Project ownership and timeline discipline

Nice to have

• Sub-GHz or ISM band experience (902-928 MHz preferred)
• Antenna design experience: patch, array, air-gap, or other constrained-form-factor antennas
• Multi-radio platform integration and coexistence (Wi-Fi + sub-GHz, Wi-Fi + cellular, or similar)
• Anechoic chamber operations or near-field scanning
• FCC Part 15 awareness as it relates to intentional radiators
• Altium or comparable PCB layout tool familiarity
