Anduril Industries, a defense technology company, is seeking a Senior RF Design & Test Engineer to join the Electrical Engineering Design team. You will collaborate with electrical, mechanical, and systems design teams, as well as EMC and compliance groups, to deliver RF hardware that meets performance and regulatory requirements.
In this role, you will:
- Ensure RF designs comply with military and commercial communication system standards and protocols, supporting spectrum authorization and 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 (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 using VNAs, spectrum analyzers, signal generators, and antenna/anechoic chambers to validate performance
- Partner with EMC and mechanical engineering to root-cause field or test failures spanning 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
- Design and integrate antennas and antenna arrays, balancing RF performance against mechanical and system constraints
- 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
- Travel up to 10% as needed
- Must be eligible to obtain and maintain a security clearance
The ideal candidate will bring strong compliance and validation instincts alongside solid RF and antenna design skills, with the ability to bridge design and validation—taking concepts from schematic and simulation through chamber characterization and compliance sign-off.
REQUIREMENTS:
- Familiarity with military and commercial communication system compliance standards, and ideally 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 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
