Principal RF Engineer, EW

About the Team

Andurils Electronic Warfare (EW) division builds next-generation electronic warfare platforms hardware-enabled software-defined systems that are fielded operational and scaling fast. The EW team operates at a tempo the defense industry isnt used to: delivering novel system configurations into active operations in days not months securing major contract awards in under 24 hours and earning unanimous fielding recommendations from government evaluators. Production is scaling from hundreds to thousands of units across multiple product variants and the release and delivery challenges are scaling with it.

What Youll Do

• 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.

Required 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

Preferred Qualifications

• Experience with 3D EM modeling and simulation (Ansys HFSS CST Feko) and nonlinear circuit simulation (harmonic balance envelope) using tools like AWR Microwave Office.
• Familiar with matching circuit RF filter design and feedback / control loop design (AGC ALC power control).
• Experience with RF shielding cavity design and isolation techniques for leakage mitigation.
• Experience with NPI manufacturing test development and production transitions.
• Familiar with FPGA or digital backend integration with RF front ends.
• Experience with PCB design / layout and guiding layout engineers.
• Familiar with programming languages like Python for analysis and test automation.
• Familiar with embedded Linux.
