Senior RF High Power Amplifier Design Engineer - Remote Opportunity

About the Role

Crescend Technologies is seeking a Senior RF High Power Amplifier Design Engineer to help us pioneer the future of solid-state, high-power RF energy. This Senior RF High Power Amplifier Design Engineer remote position involves managing, leading, and coordinating engineering activities related to RF High Power Amplifier hardware design, development, and commercialization.

What You'll Do

• Develop and problem-solve new and existing RF power amplifier designs for LMR (Low Band, VHF, UHF, 900MHz for P25 and Tetra systems).
• Lead the design and development of high-power amplifier blocks, including matching networks, bias circuits, and thermal management.
• Utilize and apply the Smith chart for impedance matching, stability analysis, and designing power transfer matching networks.
• Work with GaN and LDMOS technologies to optimize amplifier efficiency, linearity, bandwidth, and thermal management.
• Utilize simulation tools (AWR Microwave Office) to model, analyze, and optimize RF circuit performance within PCBA layouts.
• Ensure design meets all specifications, including gain, power output, efficiency, and ruggedness.
• Collaborate with Engineering and Manufacturing teams to ensure robust designs.
• Maintain detailed design documentation and simulation results.
• Mentor and train other team members as needed.

Requirements

• Proven experience in high-power RF amplifier design (e.g., 50-100W or higher).
• Strong proficiency with the Smith chart and its application in impedance matching and amplifier design.
• Expertise in GaN and/or LDMOS device technologies.
• Hands-on experience with RF simulation tools (preferably AWR Microwave Office, ADS).
• Demonstrated knowledge of RF circuit fundamentals, including small-signal analysis, stability and biasing networks, power and gain lineup analysis, Load Pull measurement.
• Strong, hands-on experience with troubleshooting, problem-solving, development, and integration skills.
• Proficient with hands-on testing of power amplifier performance (e.g., amplitude drive characterization, RF matching network with network analyzer).
• Proficiency in RF filter, coupler, balun, and combiner design.

Nice to Have

• Active Amateur Radio (Ham) license is a plus.
• Experience with project management tool Jira.

What We Offer

• Competitive salary range of $115,000 - $140,000 per year.
• Opportunity to work remotely with a flexible schedule.
• Comprehensive health benefits and wellness programs.
• Professional development opportunities and training.
• Collaborative and innovative work environment.
