CX2 is a next-generation defense technology company securing spectrum dominance for the United States and its allies. CX2 builds AI-enabled hardware and software platforms to detect, disrupt, and defend the electromagnetic spectrum across land, air, sea, and space. Headquartered in El Segundo, California, CX2 develops technology designed to give warfighters the ability to see, understand, and act across the invisible battlefield.

CX2 is seeking a Lead RF Engineer to join our growing team. The ideal candidate will have experience in cradle to grave support of various RF components - including software defined radios, amplifiers, antennas, and frequency converters. Experience leading a team of engineers is also strongly preferred.

This role requires an onsite presence in our El Segundo, CA HQ; a remote work environment is not considered for this opportunity.

Key Responsibilities

  • Cradle to grave support of various RF components - requirements capture, schematic capture, layout, bring up, measurement, production, test, and RF system level support.

  • Automate bench measurement setups for RF test data collection, and post-processing to make informed, data-driven conclusions

  • Design, integrate, and maintain complex RF systems at a blazing speed. The ideal candidate has extensive experience in New Product Introduction (NPI), design-for-manufacturing, and design-for-test.

  • Mentor and coach engineers - to effectively do this the ideal candidate would have deep experience with both eCAD and CAD software, a solid understanding of RF fundamentals, and an advanced proficiency in either Python and/or MATLAB.

    • Qualifications

  • BS/MS in Electrical Engineering, Computer Engineering, or related field

  • A minimum of 4 years’ total experience, with a minimum of 2 years’ experience leading a cross-functional engineering team

  • Experience creating link budgets and aligning them to real-world test data

  • Strong understanding of RF system parameters including gain, cascaded noise figure, figure-of-merit, linearity, and band flatness

  • Willingness to debug complex electrical systems and methodically identify root causes of issues

  • 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

  • Experience putting hardware through formal qualification campaigns and implementing robust screening of units in a manufacturing environment

  • Experience with RF systems on UAVs or for military applications

  • Experience with GNU Radio or similar DSP frameworks

  • Experience scaling RF products and technologies
