Staff RF Engineer at Chaosindustries — El Segundo, CA

Role Overview:

CHAOS is seeking a Staff RF Engineer with deep expertise in RF circuit design to lead 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.

The ideal candidate is an experienced RF circuit designer with strong hands-on experience across RF boards, MMIC-based designs, packaging constraints, and test environments, and can provide sound technical judgment when balancing performance, risk, manufacturability, and schedule.

This is a full-time, on-site position in Hawthorne, CA.

Responsibilities

• Lead design, analysis, prototyping, and tuning of 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
• Develop schematics, layouts, and design documentation in accordance with customer requirements, aerospace standards, and internal design practices
• Conduct linear, nonlinear, and electromagnetic simulations using industry-standard tools (e.g., HFSS, ADS, AWR, or equivalent)
• Support PCB layout (Altium) and RF stack-up definition, including impedance control, grounding, shielding, and isolation techniques
• 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

Minimum Requirements:

• Bachelor's degree in Electrical Engineering with 8+ years of progressively responsible RF engineering experience
• Experience developing RF hardware for aerospace, defense, avionics, radar, EW, communications, or space systems
• Strong understanding of RF fundamentals, including gain, noise figure, linearity, phase noise, stability, and impedance matching
