Job description

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.

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

ITAR Regulations

• To Conform to US Government Regulations, applicant must be a (i) U.S. Citizen or National or (ii) U.S. lawful, permanent resident (aka green card holder). Learn more about the ITAR here.

Bonus Points

• PhD in Electrical Engineering, Computer Engineering, or related field
