Senior MMIC Design Engineer

Date posted: August 17, 2026 • Location: McKinney, Texas (onsite) • U.S. citizenship required; active DoD Secret clearance required on day one.

About the role

An opportunity exists for a Senior MMIC Design Engineer to join the Microelectronics Department at Raytheon. Our team designs custom integrated circuits from DC-100 GHz that enable world-class system performance across all platforms. The successful candidate will have experience in MMIC design of functions such as HPAs, LNAs, PSAs, TDUs, or high-power switches in GaN, GaAs, or CMOS. The candidate will be responsible for the complete development cycle of the MMIC, including selection of the technology node, RF and DC topology, layout, test, evaluation, and interfacing with the internal customer. While the work is focused on Gallium Nitride and Gallium Arsenide integrated circuit development, experience in CMOS is a plus.

Responsibilities

• Assume responsibility for all aspects of the MMIC development process, including RF and DC topology choices to optimize performance, analysis and documentation of performance, layout, submission to the foundry, and verification to specifications.
• Collaborate with other MMIC engineers to share lessons-learned, grow the team’s knowledge base, improve the MMIC development process, and increase first-pass successes.
• Participate in rigorous and systematic design reviews and documentation of design decisions to ensure work outputs are of high quality and will function as simulated.

Requirements

• Degree in Science, Technology, Engineering, or Mathematics (STEM).
• Minimum of 5 years of related experience in MMIC design and/or test.
• Experience with Keysight ADS and EM tools such as HFSS or Momentum.
• Experience designing GaN, GaAs, and/or CMOS MMICs.
• Experience performing microwave and mm-wave tests in the laboratory.
• Ability to obtain and maintain a U.S. government-issued security clearance (U.S. citizenship required).

Preferred Qualifications

• Master’s or PhD in Electrical Engineering or related engineering curriculum.
• Excellent communication skills and desire to work in a team environment.
• Experience prioritizing and contributing to multiple tasks simultaneously.

Pay

The salary range for this role is $86,800 – $165,200 USD. The range provided is a good-faith estimate representative of all experience levels. RTX considers several factors when extending an offer, including but not limited to, the role, function and associated responsibilities, a candidate’s work experience, location, education/training, and key skills.

• Medical, dental, and vision insurance.
• Life insurance and short- and long-term disability coverage.
• 401(k) match.
• Flexible spending accounts.
• Flexible work schedules.
• Employee assistance program.
• Employee Scholar Program.
• Parental leave.
