Job summary

CHAOS Industries is seeking a Senior RF Engineer to design, analyze, integrate, and verify high‑reliability RF and microwave electronics for aerospace and defense. You’ll work in a cross‑functional agile team across the full product lifecycle, from architecture to post‑production sustainment.

The role emphasizes hands‑on testing with RF hardware, real measurements, and system tradeoffs. On‑site in Hawthorne, CA, with opportunities to impact mission-critical systems and product quality.

Qualifications

• Bachelor's degree in Electrical Engineering with 4+ years of progressively responsible RF engineering 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
• Ability to obtain and maintain a U.S. security clearance

Responsibilities

• 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 and component trade 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 HFSS, ADS, AWR, or equivalent
• Support PCB layout (Altium) and RF stack-up definition, including impedance control, grounding, shielding, and isolation techniques
• Experience with power amplifier design, analysis, and integration
• Experience with EMI/EMC considerations for RF systems and compliance with aerospace standards
