Senior RF Engineer
Hybrid (El Segundo)$140k - $170kFull-timePosted 6d ago
About the role
You will own Wardstone’s radar seeker, from the RF front end through signal processing to the track data that drives guidance. A senior, high-ownership role coordinating with GNC, avionics, and mechanical teams to take the seeker from the lab bench to live intercepts and, as the program grows, to hire and lead a seeker team.
Responsibilities
- Own the seeker architecture
- Define the seeker architecture and lead make-vs-buy decisions for radar sensors, front-end components, and processing hardware
- Own Tx/Rx chain analysis, including link budgets, noise figure, and phase noise, and integrate antennas with the airframe and radome
- Specify the high-speed data interfaces between the seeker and the avionics, such as high-speed ADCs/DACs and PCIe
- Select and manage suppliers for RF components and subsystems
- Build low-latency processing pipelines that detect and track high-speed targets, including Doppler processing, range-Doppler mapping, and CFAR detection
- Develop clutter and ECM rejection
- Implement and optimize the pipeline on the flight processor [FPGA / GPU / embedded CPU]
- Own the seeker-to-guidance interface. Work with the GNC team to fuse radar tracks with IMU, GPS, and onboard state estimates (EKF/UKF) for closed-loop terminal guidance
- Design RF test rigs and run hardware-in-the-loop tests using anechoic chambers, radar scene generators, RCS reference targets, and flight dynamics models
- Lead seeker testing from the lab bench through environmental qualification and flight test
Qualifications
- B.S. in Electrical Engineering, Physics, Aerospace Engineering, or a related field. M.S. preferred
- 6+ years designing, integrating, or testing radar systems, including ownership of a significant subsystem through hardware test
- Deep understanding of radar physics and electromagnetics, including noise figure, phase noise, and link budget analysis
- Strong DSP background, with experience implementing real-time radar detection and tracking
- Proficiency in C++ and Python, and experience with real-time or embedded systems
- Hands-on lab experience testing radar architectures (FMCW, pulsed Doppler, or AESA) with spectrum analyzers, VNAs, and oscilloscopes
- Experience sourcing RF components and making make-vs-buy decisions
- Must be a U.S. person as defined by ITAR (U.S. citizen, lawful permanent resident, or protected individual). [Must be eligible to obtain a U.S. security clearance.]
