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.
• A passion for dogs is a plus — our NYC office is dog-friendly
