Description

  • Own RF front-end architecture, design, integration, validation, and production for aircraft, ground support infrastructure, and future autonomous logistics platforms.
  • Develop multi-radio wireless architectures supporting LTE, 5G, GNSS, Wi-Fi, Bluetooth, ADS-B, UAT, ISM radios, telemetry, command-and-control, and emerging V2V technologies.
  • Define next-generation air-to-ground and vehicle-to-vehicle wireless architectures for scalable autonomous fleet operations.
  • Evaluate and integrate chip-down wireless solutions, RF front-end modules, cellular modems, GNSS receivers, Wi-Fi SoCs, and integrated radio platforms.
  • Translate system-level communication, navigation, regulatory, and operational needs into RF front-end specifications and verification plans.
  • Design RF signal chains, including PAs, LNAs, filters, duplexers, diplexers, multiplexers, RF switches, matching networks, and antenna interfaces.
  • Incorporate RF coexistence, interference management, isolation, and receiver desense mitigation into wireless architecture and design.
  • Perform RF system analysis such as link budgets, cascade analysis, noise figure, linearity, dynamic range, sensitivity, and interference budgeting.
  • Support schematic capture, PCB layout reviews, RF routing, stack-up definition, grounding, shielding, and design-for-manufacturing activities.
  • Plan and execute RF validation, coexistence testing, desense characterization, environmental qualification, production verification, and regulatory certification.
  • Work with suppliers and manufacturing partners to define RF specifications, production test methods, calibration procedures, and quality controls.
  • Mentor engineers and help establish RF architecture standards, validation processes, and long-term wireless technology roadmaps.

Requirements

  • Bachelor's degree in Electrical Engineering or a related technical field.
  • Typically 7 or more years of professional experience designing RF front-end hardware or wireless communication systems for production products.
  • Strong understanding of RF system architecture, cascaded RF performance, receiver sensitivity, noise figure, linearity, blocking, dynamic range, and front-end optimization.
  • Demonstrated experience designing RF front ends for LTE, 5G, Wi-Fi, GNSS, Bluetooth, ISM, or similar wireless communication systems.
  • Experience developing multi-radio platforms with complex integration and wireless system requirements.
  • Hands-on experience with RF signal chains using LNAs, PAs, filters, duplexers, diplexers, multiplexers, RF switches, front-end modules, and impedance matching networks.
  • Strong understanding of RF coexistence, receiver desense mechanisms, interference coupling, intermodulation products, harmonic generation, and mitigation techniques.
  • Experience taking RF hardware from concept through integration, verification, certification, and production.
  • Familiarity with RF PCB layout, transmission lines, grounding, shielding, power integrity, and electromagnetic compatibility.
  • Hands-on experience with vector network analyzers, spectrum analyzers, signal generators, power meters, network emulators, and other RF measurement equipment.
  • Strong written and verbal communication skills with the ability to explain technical tradeoffs across multidisciplinary engineering teams.
  • Ability to operate independently while driving technically complex wireless programs from concept through production.
  • Master's degree or PhD in Electrical Engineering or a related field preferred.
  • Experience with ADS-B, UAT, aviation communications, or autonomous aircraft communication systems preferred.
  • Experience developing air-to-ground communication systems or emerging V2V communication technologies preferred.
  • Experience with cellular carrier certification, PTCRB, GCF, and international cellular deployments preferred.
  • Experience evaluating and integrating chip-down wireless SoCs and highly integrated RF front-end modules preferred.
  • Familiarity with RF simulation tools such as Keysight ADS, Cadence AWR, Ansys HFSS, CST Studio Suite, or similar platforms preferred.
  • Experience with MIMO systems, antenna diversity, carrier aggregation, and advanced LTE/5G RF architectures preferred.
  • Knowledge of EMI/EMC design practices, coexistence testing, passive intermodulation, and regulatory compliance preferred.
  • Familiarity with Python, MATLAB, or equivalent tools for RF analysis, automation, and data processing preferred.
  • Experience working directly with RF semiconductor vendors, cellular module suppliers, contract manufacturers, certification laboratories, and wireless carriers preferred.
