• Architect and design complex RF subsystems, including amplifiers, mixers, converters, filters, and transceivers.
• Perform high-level system modeling, simulations, trade studies, and design optimizations to meet performance, cost, and environmental constraints.
• Drive prototype development, hands-on testing, troubleshooting, and performance verification using advanced RF test equipment.
• Collaborate cross-functionally with internal teams, customers, and technical leads to ensure successful execution of project deliverables.
• Contribute to strategic product planning and technology roadmaps based on customer needs and market trends.
• Provide technical leadership and mentorship to junior engineers and engineering technicians.
• Support proposals, cost estimates, and technical responses for new business opportunities.
• Serve as industry expert on RF and microwave application needs to advise customers on optimal solutions and present proposals to technical experts from customers.

Requirements:

Qualifications

• Bachelor's degree in Electrical Engineering, Physics, or a related field (Master’s or PhD ).
• 7+ years of industry experience in RF and microwave system design, test, and integration.
• Deep understanding of RF system architecture, component behavior, and signal integrity across frequency bands from MHz to tens of GHz.
• Proficiency in industry-standard tools such as Keysight ADS, HFSS, MATLAB, and Altium Designer (or equivalents).
• Experience with high-power and low-noise amplifier chains, frequency conversion, and transmitter/receiver (Tx/Rx) systems.
• Skilled in RF cascade analysis, impedance matching, intermodulation distortion, and thermal effects.
• Proven track record of leading complex engineering projects from concept to production.
• Strong interpersonal and communication skills with the ability to present to internal and external stakeholders, including customers and leadership teams.
• U.S. Person as defined by U.S. export control regulations (required).

Experience

• Experience in defense or aerospace RF systems.
