About the role

Senior RF Design and Test Engineer to join Anduril's Electrical Engineering Design team, collaborating with electrical, mechanical, and systems teams, as well as EMC and compliance groups to deliver RF hardware meeting performance and regulatory requirements. Emphasis on compliance, validation, RF/antenna design, and ability to bridge design and validation from schematic/simulation to chamber characterization and compliance sign-off.

Responsibilities

  • Ensure RF designs comply with relevant military and commercial communication system standards and protocols, and support spectrum authorization/certification processes for military RF systems.
  • Evaluate designs against SAR and military RF exposure limits, coordinating testing as needed.
  • Assess coexistence and desense between onboard radios (e.g., UWB, GNSS, LTE) — distinguishing conducted vs. radiated coupling paths — and recommend mitigations for cross-band interference and antenna detuning.
  • Bench and chamber test RF hardware and antennas (e.g., using VNAs, spectrum analyzers, signal generators, and antenna/anechoic chambers) to validate performance against requirements.
  • Partner with EMC and mechanical engineering to root-cause field or test failures that span RF, electrical and mechanical domains.
  • Design RF circuits and subsystems, including front-ends, amplifiers, filters, and transceivers; perform link budget and system-level RF analysis, including receiver saturation and sensitivity trade-offs.
  • Design and integrate antennas and antenna arrays, balancing RF performance against mechanical and system constraints, including connector/mechanical interface tolerances.
  • Support GPS/GNSS receiver design and integration, including active antenna bias circuits, filtering, and interference immunity.
  • Utilize 3D EM simulation tools and S-parameter analysis to model and optimize RF and antenna performance.
  • Review schematics and CAD designs for RF performance, signal integrity, and manufacturability.

Qualifications

  • Familiarity with military and commercial communication system compliance standards, and exposure to spectrum authorization or certification processes for military RF systems.
  • Familiarity with SAR and military RF exposure limits (e.g., MPE) and how they influence antenna placement and design.
  • Experience with multi-radio coexistence and desense analysis, including UWB emissions requirements, and the ability to distinguish conducted from radiated coupling mechanisms.
  • Proficiency with RF bench equipment (VNA, spectrum analyzer, signal generator) and prior experience testing antennas in antenna/anechoic chambers.
  • Hands-on experience designing and testing RF circuits, subsystems, or antennas, including antenna arrays.
  • Working knowledge of GPS/GNSS receiver architectures, active antenna bias circuits, and RF connector/mechanical interface design considerations.
  • Strong background in schematic reviews, CAD analysis, and RF/high-speed PCB layout best practices.
  • Proficiency with 3D EM simulation software (e.g., Ansys HFSS, Altair FEKO, or CST Studio Suite) for S-parameter analysis and RF/antenna performance modeling.
