Staff Antenna/ RF Systems Engineer

What You'll Do: • Own end-to-end antenna design for Fi products, from proof-of-concept through mass production.

• Lead antenna architecture and contribute to overall system architecture, including RF component selection, schematic capture, and RF PCB layout.

• Design, optimize, tune, and validate antennas to meet aggressive constraints around size, performance, reliability, and manufacturability.

• Work closely with mechanical, industrial design, firmware, leadership, and overseas engineering teams to ensure seamless antenna integration into the product.

• Push antenna performance using a mix of best practices, state-of-the-art approaches, and novel designs where needed — because every dB matters.

• Partner directly with overseas CM/JDM teams on antenna implementation, performance testing, compliance, and production ramp.

What You'll Bring: • 8+ years of experience designing electrically small antennas for consumer electronics or similar products.

• Bachelor’s or Master’s degree in Electrical Engineering or a related field.

• Proven ability to translate product-level connectivity requirements into RF system and antenna requirements, including managing external consultants and fabrication vendors as needed.

• Deep hands-on experience with custom antenna design in the ~600 MHz to 3 GHz range, including multiband designs, polarization control, antenna isolation in close proximity, and performance optimization near human or animal tissue.

• Strong understanding of antenna integration, including use of enclosures and mechanical structures as part of the antenna system.

• Experience across common antenna fabrication methods and materials, including LDS, FPC, PCB, stamped metal, and ceramic chip antennas, with an understanding of material tradeoffs.

• Comfort building scrappy prototypes using rapid methods such as hand-formed copper, milling, or 3D printing.

• Proficiency with 3D electromagnetic simulation tools for antenna design.

• Strong RF lab skills, including conducted and radiated measurements, antenna tuning, and managing cable effects when testing electrically small antennas.

• Experience operating semi-anechoic chamber testing and supporting regulatory and compliance testing.

• Ability to design simple schematics and PCBs to support antenna prototyping and test.

• Familiarity with firmware and software requirements for RF validation, including sensitivity metrics like BER and PER, and comfort using scripts (e.g., Python) for test automation or analysis.

• Proven track record leading antenna designs from prototype through mass production.

• Willingness to travel to China as needed.
