About the role

Principal RF Engineer role in Anduril's Electronic Warfare (EW) division focusing on design and development of RF radio architectures, signal chains, and full lifecycle PCBA ownership for military-grade systems.

Responsibilities

  • Design and develop complete RF radio architectures (receivers, transmitters, transceivers) from requirements through production.
  • Architect and design RF up-conversion and down-conversion signal chains, optimizing between noise, distortion, and dynamic range trade-offs.
  • Modeling, simulation, analysis, design, test, and optimization of active and passive RF and/or mixed signal circuits.
  • Select, characterize, and integrate high-speed data converters (ADCs and DACs) and associated baseband driving, filtering, and interface circuits.
  • Design and optimize clock trees, reference oscillators, and LO/synthesizer architectures (DDS, PLL, VCO-based) with emphasis on phase noise, spurious, and settling time.
  • Perform system-level spur analyses (mixer spurs, synthesizer harmonics, clock coupling, image rejection) and develop mitigation strategies.
  • Own radio PCBA design and test through the full lifecycle: analysis (harmonic, spur, etc.), component selection (ADC/DAC, mixer, filters, etc.), technical data package (schematic/layout), board bring up, test, DVT/ATP, and new product introduction to manufacturing.
  • Assist with feasibility studies, requirements definition, and system integration as needed.

Qualifications

  • B.S. Electrical Engineering or equivalent
  • 7+ years experience
  • Experience designing complete RF receiver and/or transmitter signal chains using common architectures (direct conversion, zero-IF, single-IF, dual-IF, clock-chains), including cascade analyses and architecture trade-off studies.
  • Experience with off the shelf discrete RF components like LNAs, filters, mixers, PLLs / synthesizers, oscillators, amplifiers, variable attenuators, switches, power detectors, and limiters.
  • Experience with high-speed data converters (ADC/DAC), including selection, characterization, integration, and associated anti-alias / reconstruction filter design.
  • Experience with synthesizer and LO design including PLL loop filter optimization, phase noise analysis, and spur management.
  • Experience with schematic capture, board bring up, test, and optimization.
  • Experience with circuit modeling and simulation using tools like Ansys Electronics Desktop (Nexxim, SiWave) and Cadence AWR Microwave Office.
  • Proficient with RF test equipment including VNAs, spectrum analyzers, signal generators, power meters, and oscilloscopes.
  • Must be able to obtain and hold a U.S. Secret security clearance
