Senior RF Engineer - Own the radar seeker that guides a next-generation interceptor to its targetEl Segundo, California | On-site
Opportunity SummaryThis role owns the radar seeker end to end, from the RF front end through signal processing to the target tracks that feed guidance. The seeker is what tells the interceptor precisely where to strike, and you will be its technical owner.
You will make the core architecture and make-vs-buy calls, build out RF test infrastructure, and work hand in hand with the founders and with GNC, avionics, and mechanical engineers to move the seeker from bench to live intercept. As the program expands, you will help hire and lead a dedicated seeker team.
Job Duties- Define the seeker architecture and lead make-vs-buy decisions on radar sensors, front-end components, and processing hardware
- Own transmit and receive chain analysis, including link budgets, noise figure, and phase noise
- Integrate antennas with the airframe and radome
- Specify high-speed data interfaces between the seeker and avionics, such as ADCs, DACs, and PCIe
- Select and manage RF component and subsystem suppliers
- Build low-latency detection and tracking pipelines, including Doppler processing, range-Doppler mapping, and CFAR
- Develop clutter rejection and electronic countermeasure resilience
- Implement and optimize processing on the flight processor (FPGA, GPU, or embedded CPU)
- Own the seeker-to-guidance interface and work with GNC to fuse radar tracks with IMU, GPS, and onboard state estimates for terminal guidance
- Design RF test rigs and run hardware-in-the-loop testing with anechoic chambers, scene generators, RCS references, and flight dynamics models
- Lead seeker testing from lab bench through environmental qualification and flight
Qualifications- Bachelor's degree in electrical engineering, physics, aerospace engineering, or a related field (master's preferred)
- 6+ years designing, integrating, or testing radar systems, including ownership of a major subsystem through hardware test
- Deep knowledge of radar physics and electromagnetics, including noise figure, phase noise, and link budgets
- Strong DSP background with real-time radar detection and tracking implementation
- Proficiency in C++ and Python with real-time or embedded systems experience
- Hands-on lab testing of FMCW, pulsed Doppler, or AESA architectures using spectrum analyzers, VNAs, and oscilloscopes
- Experience sourcing RF components and making make-vs-buy decisions
- U.S. Person status required (ITAR) and ability to obtain a U.S. security clearance
Preferred Experience- Missile seeker, air-to-air, counter-ballistic tracking, or EW resilience experience
- FPGA signal processing (VHDL or Verilog) or GPU acceleration for radar
- Antenna arrays, beamforming, radome integration, or atmospheric attenuation modeling
- RCS modeling and synthetic target generation
- High-G, vibration, and thermal environmental testing such as MIL-STD-810
- Prior early-stage startup experience
Compensation Details$140,000 - $180,000 + equity
