CX2 is a next-generation defense technology company founded to deliver spectrum dominance for the United States and our allies. CX2’s AI-enabled hardware and software platforms detect, disrupt and defend the electromagnetic spectrum across land, air, sea and space domains.

CX2 is seeking a skilled RF Hardware Engineer to join our growing team. The ideal candidate will have experience in designing, testing and building RF Systems (Tx / Rx) for RF signals (ex. communications, RADAR, navigation) UHF through X-Band.
 
This role requires an onsite presence in our El Segundo, CA HQ; a remote work environment is not considered for this opportunity.
  • Design, validate & deliver RF payload subsystems: Design, Integration and Testing of Antennas, RF front ends, SDRs and provide validation of operation. Support development and analysis of RF performance metrics.
  • Own requirements, ICDs, and verification from concept through delivery
  • Stay current: Track and insert advances in relevant technologies, SDRs, RF Systems, RF machine learning, and PNT.
  • BS/MS in Electrical Engineering, Computer Engineering, or related field
  • Antenna and receiver design across analog/RF/mixed-signal domains: mixers, PLLs/LOs, gain/linearity/noise trades; ability to turn simulations into reality.
  • Channelizers & wideband architectures: filter banks, analog/digital down conversion, sample-rate planning, clocking/synchronization.
  • Willingness to support critical test events that occasionally require extended hours/weekends
  • Ability to obtain and maintain a security clearance
  • Must be a U.S. Person (see ITAR Regulations below) due to required access to U.S. export-controlled information or facilities
  • PhD in Electrical Engineering, Computer Engineering, or related field
  • 5+ years’ experience with EW subsystems and payloads
  • EA/ECM technique design (deception, Digital RF Memory, coherent/non-coherent techniques)
  • Digital Signal processing: Design characterize and deliver channelizers, wideband detection/classification, MIMO/digital-arrays, and algorithms in MATLAB/Python/C++
  • Communication / Waveform system design
  • RF machine learning for emitter ID, modulation/classification, anomaly detection, PDW creation
  • Tools Experience: ADS/AWR/SystemVue, MATLAB/Simulink, Python (NumPy/SciPy), GNU Radio/SDR (USRP/RFSoC), VITA-49; HDL/firmware experience; also helpful (Vivado/Quartus/Libero).
  • Clearance: Active Secret or ability to obtain and maintain; TS/SCI eligibility preferred. ITAR/EAR-controlled work. Learn more about Security Clearances here.
  • Field work: supporting periodic travel for flight tests and customer demonstrations/support
  • Mindset: Builder-tester who loves first-principles RF, rapid lab iteration, and getting hardware flying fast
  • Competitive salary, stock options and benefits, including health, vision and dental.
  • 401K enrollment at 90 days.
  • Generous PTO + most Federal Holidays observed.
  • Collaborative and inclusive work environment.
  • Access to the latest tools and technologies.
