Senior MMIC Designer

Senior MMIC Designer

Requirements

• BSEE with 18+ years or MSEE with 15+ years of experience in RF/MMIC design.
• Strong theoretical background in RF/microwave distributed-element circuits and transmission lines.
• Proven track record of successful MMIC product releases to production, preferably for high-frequency and/or high-power applications (X-band, K-band, Ka-band, mmWave preferred).
• Expertise in electromagnetic simulation techniques.
• Familiarity with small-signal and large-signal models of GaAs HEMTs and GaN-on-SiC HEMTs.
• Experience with PCB and hybrid module design, including MMIC and hybrid circuit integration.
• Proficient in design techniques such as nonlinear simulation, Cripps Analysis, and stability analysis using loop-gain methods.
• Strong understanding of load-pull contours and the use of load-pull data to optimize high-power amplifier designs.
• Expertise in MMIC power amplifier design, including nonlinear circuit design and simulation (harmonic balance, load-pull), impedance matching techniques for high-power, high-PAE amplifiers, thermal analysis and thermal management strategies, and advanced stability analysis techniques.
• Deep knowledge of GaAs pHEMT, GaN-on-SiC HEMT, or other advanced compound semiconductor technologies.
• Experience with advanced RF/microwave packaging technologies.
• Must be a U.S. Citizen with the ability to obtain and maintain a security clearance.

Responsibilities

• Perform detailed design, simulation, layout, and validation of advanced GaN and GaAs MMIC products, with a focus on high-power amplifiers operating at RF, microwave, and millimeter-wave frequencies.
• Define MMIC specifications based on system-level customer requirements and trade-off analyses.
• Utilize industry-standard simulation tools (ADS, Cadence AWR, HFSS, Sonnet, AXIEM) for linear, nonlinear, and electromagnetic analysis.
• Support laboratory validation, including S-parameters, output power, efficiency, load-pull, noise figure, and linearity measurements.
• Provide technical mentorship and guidance to junior designers and engineering teams.
• Collaborate with cross-functional teams (program management, mechanical engineering, manufacturing, sales, quality, and leadership) throughout the product development cycle.
• Assist in proposal efforts, system architecture studies, and internal R&D planning activities.
• Ensure timely project execution while contributing to continuous process improvements and the advancement of design best practices.
• Document design activities, development processes, and design reviews in accordance with company and industry standards.

Preferred Qualifications

• Strong technical judgment and engineering decision-making skills, especially in complex or ambiguous situations.
• Excellent written and verbal communication skills, including technical documentation and presentations.
• Self-motivated, detail-oriented, and capable of managing multiple projects simultaneously while meeting aggressive schedules.
• Strong teamwork skills, with the ability to collaborate effectively across cross-functional and customer-facing teams.
