Principal Design Engineer RFIC


Unleash Innovation. Lead the Future of High-Frequency Design. Step into a pivotal role where your expertise shapes next-gen RF and microwave ICs. We're seeking a Principal MMIC Design Engineer to drive the full development cycle-from blank page to fully qualified product. You'll be at the forefront of innovation, working with cutting-edge GaAs and GaN technologies in a collaborative, fast-paced environment.


This is more than just a design job-it's an opportunity to lead, influence, and deliver at a global scale.


What You'll Do as Principal Design Engineer RFIC:

  • Own the full IC design flow: from initial spec development to validation and volume release.
  • Run advanced simulations, validate performance, and deliver production-ready designs.
  • Collaborate with cross-functional teams-product, test, applications, and customer engineering-to bring high-performance RFICs to market.
  • Act as the technical lead on projects, mentoring engineers and ensuring on-time execution.
  • Support lab characterization, debug, and refinement of MMICs with hands-on precision.

What You Bring as Principal Design Engineer RFIC:

  • A deep command of GaAs and GaN MMIC design, simulation, and optimization techniques.
  • 15+ years of RFIC design success, with real-world product launches and field-proven results.
  • Mastery in designing critical RF topologies: LNAs, TWAs, VGAs, PAs, gain blocks, detectors, and more.
  • Bonus if you've worked on: mixers, phase shifters, attenuators, or low phase noise amps.
  • Proficiency in ADS, AWR, EM simulation tools, and lab measurement equipment.
  • Skilled in thermal analysis, validation strategies, and production-level qualification processes.
  • Experience leading or mentoring design teams and coordinating across disciplines.
  • Strong project planning skills and the drive to push a product from idea to market impact.

What Sets You Apart:

  • B.S. + 12 years, M.S. + 10 years, or Ph.D. + 6 years of hands-on RF design experience.
  • Proven ability to lead technical programs, influence direction, and guide junior engineers.
  • A mindset of ownership-you don't just design, you deliver.

The company you will join as Principal Design Engineer RFIC:

  • Are a world-class technology leader known for precision signal processing, power management, and cutting-edge mixed-signal solutions.
  • Have a strong global footprint and a history of consistent multi-billion-dollar annual revenue.
  • You will work within a high-performing and well-resourced team driving innovation in markets such as industrial, automotive, communications, and healthcare.
  • Have structured training programs and continuous learning opportunities through internal platforms, technical workshops, and leadership development.
  • Will be able to offer clear career progression paths, with internal mobility, technical ladders, and support for professional growth.
  • Join an organization that invests heavily in R&D and innovation, with an eye on long-term technological leadership and sustainability.
