About the role

RF antenna engineer responsible for end-to-end wireless design for a first-generation consumer wearable/device, architecting a multi-radio ecosystem (Cellular, Wi-Fi, BT, GNSS, NFC, UWB) within a compact envelope to deliver optimal wireless functionality.

Responsibilities

  • Architect the multi-radio systems, ensuring coexistence and optimal performance across a wide spectrum (sub-GHz to 8GHz+).
  • Design and simulate custom, miniaturized antennas (LDS, FPC, or metal frame) for high-density environments.
  • Partner with Industrial Design (ID) and Mechanical Engineering (ME) to balance aesthetic and RF transparency.
  • Develop RF strategies that prioritize ultra-low power consumption for battery-constrained performance.
  • Own the product through EVT, DVT, and PVT phases, managing factory calibration, OTA testing, and global regulatory certifications (FCC/CE/PTCRB/GCF).
  • Lead engagements with chipset vendors and antenna fabricators to push commercially possible limits.

Qualifications

  • 10+ years in RF/Antenna design, with at least 2 full lifecycles leading a high-volume consumer electronic product to mass market.
  • Expert-level proficiency in ANSYS HFSS, CST Studio Suite, or similar EM simulation tools.
  • Full-stack understanding of RF front-end (RFFE) design, including filters, switches, LNAs, and matching networks.
  • Proven experience with 5G/4G LTE, Wi-Fi 6E/7, Bluetooth 5.x, GNSS (L1/L5), and UWB.
  • Strong hands-on skills with VNA, Spectrum Analyzers, and Anechoic Chamber testing (TRP/TIS).
