Senior RF Front-End Design Engineer

Job description

Our customers include the world’s largest and most prominent healthcare systems, governments, retailers, restaurants and global businesses who rely on us to save lives, reduce emissions, increase economic opportunity, and provide delivery from point A to point B as fast as possible. The drone is only 15% of what we’ve built to enable seamless, reliable, global operations.

Our system strengthens supply chains, reduces congestion, and gives people time back. With more than 140 million commercial autonomous miles safely flown, Zipline is redefining access to healthcare, consumer products, and food across the globe.

We operate at a global scale and are looking for practical problem solvers who…

Job responsibilities

  • Own RF front-end architecture, design, integration, validation, and production for Zipline aircraft, ground support infrastructure, and future autonomous logistics platforms.
  • Develop highly integrated multi-radio architectures supporting LTE, 5G, GNSS, Wi-Fi, Bluetooth, ADS-B, UAT, ISM radios, telemetry, command-and-control, and emerging V2V communication technologies.
  • Define next-generation air-to-ground and vehicle-to-vehicle wireless architectures that enable scalable autonomous fleet operations.
  • Evaluate and integrate chip-down wireless solutions, RF front-end modules, cellular modems, GNSS receivers, Wi-Fi SoCs, and future integrated radio platforms.
  • Translate system-level communication, navigation, regulatory, and operational requirements into RF front-end specifications and verification plans.
  • Design RF signal chains including power amplifiers, low-noise amplifiers, filters, duplexers, diplexers, multiplexers, RF switches, matching networks, and antenna interfaces.
  • Design RF front-end architectures that enable reliable operation of multiple simultaneous wireless systems across airborne and ground platforms.
  • Incorporate RF coexistence, interference management, isolation, and receiver desense mitigation into overall wireless architecture and front-end design.

Job requirements

  • Master's degree or PhD in Electrical Engineering or a related field.
  • Experience with ADS-B, UAT, aviation communications, or autonomous aircraft communication systems.
  • Experience developing air-to-ground communication systems or emerging V2V communication technologies.
  • Experience with cellular carrier certification, PTCRB, GCF, and international cellular deployments.
  • Experience evaluating and integrating chip-down wireless SoCs and highly integrated RF front-end modules.
  • Familiarity with RF simulation tools such as Keysight ADS, Cadence AWR, Ansys HFSS, CST Studio Suite, or equivalent platforms.
  • Experience with MIMO systems, antenna diversity, carrier aggregation, and advanced LTE/5G RF architectures.
  • Knowledge of EMI/EMC design practices, coexistence testing, passive intermodulation, and regulatory compliance.
