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.

High levels of responsibility and autonomy.

Professional growth and development opportunities.

Access to the hardest problems in electronic warfare.

To conform to U.S. Government export regulations, applicant must be a US Citizen, Green Card holder, or be eligible to obtain the required authorizations from the U.S. Department of State. Learn more about the ITAR here.
