The posting

Responsibilities

  • Define and lead the RF/microwave design strategy across our photonic and semiconductor product lines, setting technical direction for antenna, matching network, and high-frequency interconnect architecture.
  • Serve as the top technical authority on RF/EM simulation, providing expert guidance on Ansys HFSS, SIwave, Q3D, and ADS to resolve the most complex signal and power integrity challenges.
  • Lead RF measurement and validation strategy, including S-parameter testing, antenna far-field characterization, and anechoic chamber measurement programs, and establish best practices across teams.
  • Provide technical leadership and mentorship to SI/PI, hardware, and packaging engineers, ensuring RF performance is preserved across the full signal chain, from chip package through PCB.
  • Own resolution of critical, escalated RF issues including impedance mismatch, insertion loss, return loss, and EMI/EMC compliance, acting as the final technical escalation point.
  • Drive RF design strategy for new product introduction (NPI), partnering with cross-functional leadership to align technical roadmaps with business priorities.
  • Author and review technical documentation, design standards, and specifications for RF subsystems across the organization.
  • Represent RF engineering capability with external partners, PCB fabrication/assembly vendors, and key customers.
  • Track emerging high-frequency protocols and industry standards (100G/200G/400G/800G) and translate them into forward-looking design roadmaps.
  • Mentor and develop junior and mid-level RF engineers, building organizational depth in RF competency.

Requirements

  • Bachelor’s, Master’s, or Ph.D. in Electrical Engineering, RF/Microwave Engineering, or a related field.
  • Minimum 10+ years of RF/microwave design experience, with a demonstrated track record of technical leadership.
  • Deep expertise in EM simulation tools such as Ansys HFSS, SIwave, Q3D, and ADS, with demonstrated ability to resolve highly complex RF challenges.
  • Extensive hands-on experience with RF measurement equipment, including Vector Network Analyzers (VNA) and antenna far-field measurement systems.
  • Deep understanding of RF fundamentals, including impedance matching, S-parameters, antenna theory, and EMI/EMC principles.
  • Demonstrated experience leading or mentoring engineering teams.
  • Strong track record of cross-functional collaboration at a senior level.
  • Excellent written and verbal communication skills in English, with the ability to communicate technical strategy to senior leadership.

Preferred Qualifications

  • Experience in optical communications or semiconductor packaging environments at a senior or principal level.
  • Deep familiarity with high-speed protocols such as PCIe, DDR, or high-speed SerDes.
  • Experience with chip-package-board co-design and simulation at scale.
  • Track record of leading mass production ramp and yield improvement initiatives.
  • Patents or publications in RF/microwave design.

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
