About The Position

As an R&D RF and YIG Design Engineer at Keysight, you'll be part of a collaborative and inclusive environment located primarily in Santa Rosa, CA. Our team, housed within Keysight Laboratories, is dedicated to shaping the future of technology. By joining us, you'll play a pivotal role as part of a team creating, validating, and implementing next-generation, high-performance microwave/mm-wave and frequency synthesis solutions to set Keysight products apart from the competition. You'll work on pioneering projects, driving advancements in YIG-based solutions. The ideal candidate will have a strong foundation in microwave engineering, magnetics, and simulation, and be comfortable working across multiple domains including circuit design, electromagnetic modeling, and system-level integration. This senior-level role requires technical leadership in defining design approaches, guiding trade-off decisions, mentoring engineers, and driving alignment across research, product development, manufacturing, and test teams.

Requirements

BS, MS, or PhD in Electrical Engineering or Physics, or equivalent, with minimum of 6+ years of relevant experience
Strong knowledge of RF and microwave theory, including S-parameters, filter theory and active microwave circuits and RF building blocks
Hands-on experience with RF measurement equipment, such as network analyzers, and spectrum and signal analyzers
Proficiency with RF/microwave simulation tools, including both circuit and full-wave EM tools (e.g., ADS, EMPro, CST, HFSS, COMSOL)
Strong understanding of magnetics, including electromagnets, magnetic circuits, hysteresis effects
Strong teamwork and interpersonal skills, with a collaborative spirit.
Ability to deal with uncertainty in requirements from product partners and drive to alignment.
Demonstrated ability to lead complex technical investigations, make data-driven trade-off decisions, and communicate recommendations to technical and business stakeholders.
Candidates must be local or willing to relocate to Santa Rosa, CA
This position requires access to certain goods, software, technology, or technical data subject to U.S. export control laws and regulations. Candidates must be a U.S. citizen or lawful permanent resident of the U.S., or protected individual, having authorization from the U.S. government for export-controlled items under 8 U.S.C. 1324b(a)(3).
