RF Hardware Engineer

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.

Key Responsibilities

• 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.

Qualifications

• 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

Bonus Points

• 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

What We Offer

• 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.

ITAR Regulations

• 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.
