RF Engineer

CHAOS Industries is redefining modern defense with a multi-product portfolio that gives the ultimate advantage—domain dominance. The company's products are powered by Coherent Distributed Networks (CDN™), empowering warfighters, commercial air operators, and border protection teams to act faster, adapt rapidly, and stay ahead of evolving threats.

CHAOS Industries was founded in 2022 and has raised a total of $1 billion in funding from leading investors, including 8VC, Accel, and Valor Equity Partners. The company is headquartered in Los Angeles, with offices in Washington, D.C., San Francisco, San Diego, Seattle, and London. For more information, please visit  .

CHAOS is seeking a Senior RF Engineer to support the design, analysis, integration, and verification of high-reliability RF and microwave electronics for aerospace and defense applications. This role works as part of a cross-functional, agile development team and spans the full product lifecycle, from early architecture and component trade studies through detailed design, testing, production support, and post-production sustainment of mission-critical systems.

This is a hands-on hardware role focused on translating system requirements into robust RF implementations, integrating and troubleshooting prototype hardware, and validating performance through lab and field experimentation. The ideal candidate is comfortable using simulation tools to guide decisions, but is strongest when working with real hardware, real measurements, and real system tradeoffs.
This is a full-time, on-site position in Hawthorne, CA.

• Design, analyze, prototype, and tune RF circuit boards incorporating catalog MMICs, including LNAs, power amplifiers, baluns, filters, mixers, and associated bias and matching networks
• Perform architecture development andcomponenttrade studies to meet system-level RF performance requirements
• Plan and execute RF testing and characterization, including integration and troubleshooting at the board, module, and subsystem levels
• Contribute to the design and specification of RF test equipment, fixtures, and automation
• Collaborate with systems, power, digital, mechanical, and software engineers to ensure RF designs integrate cleanly within larger systems
• Serve as a technical contributor from development through production and post-production, including failure analysis and field support
• Support linear, nonlinear, and electromagnetic simulations using industry-standard tools (e.g., HFSS, ADS,AWR,or equivalent)
• Support design, analyze, prototype, and tune RF circuit boards incorporating catalog MMICs, including LNAs, power amplifiers, baluns, filters, mixers, and associated bias and matching networks
• Support PCB layout(Altium) and RF stack-up definition, including impedance control, grounding, shielding, and isolation techniques
• Bachelor's degree in Electrical Engineeringwith4+ years ofprogressively responsibleRFengineering experience, or a Masters with 3+ years, or a PhD of relevant experience
• Hands-on experience with RF test equipment (e.g., VNAs, spectrum analyzers, signal generators, power meters)
• Strong understanding of RF fundamentals and how they add to system-level performance, including gain, noise figure, linearity, phase noise, stability, and impedance matching
• Demonstrated ability to analyze, troubleshoot, and resolve complex RFcircuitperformance issues
• Ability to obtain andmaintaina U.S. security clearance

• Experience with radar, EW, remote sensing, or communications subsystem architecture and performance analysis.
• Experience planning and executing lab and field experiments, including test planning, data collection, and measurement correlation.
• Experience with RF front-end prototyping and integration, including LNAs, PAs, filters, mixers, frequency conversion chains, and antenna interfaces.
• Familiarity with antenna/system integration, EMI/EMC, environmental constraints, and applicable aerospace/defense standards.
• Experience correlating simulation, analysis, and measured data to refine designs and retire technical risk.
• Experience supporting design reviews, customer interactions, verification planning, and transition from development into production.
• Active U.S. security clearance.
• Experience with power amplifier design, analysis, and integration
• Familiarity with EMI/EMC considerations for RF systems and compliance with applicable aerospace standards
• Experience with mixed-signal or RF/digital interfaces
• Knowledge of…
