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.

• Design and develop YIG-based components and subassemblies, including YIG filters and oscillators
• Determine and develop approaches to complex research and development assignments across end-to-end product development, from concept and simulation through prototyping, testing, and production
• Apply multi-physics principles and simulations to optimize performance and reliability
• Perform RF/microwave analysis and validation, including S-parameter characterization and phase noise evaluation
• Design and implement high-current driver circuits for YIG devices
• Collaborate with cross-functional teams including systems, manufacturing, and test engineering
• Provide technical leadership by guiding architecture decisions, reviewing design approaches, mentoring engineers, and influencing cross-functional technical direction.
• Support transition of designs into manufacturing and production environments

• Educational Background: 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.

• Experience with advanced electromagnetic and magnetic simulations, including transient behavior, loss mechanisms (hysteresis, eddy currents)
• Solid experience in discrete circuit design, particularly high-current driver circuits
• Background in filter and/or oscillator design
• Experience with low phase noise design and optimization
• Knowledge of material science, particularly: crystalline structures, magnetic materials and steel alloys
• Familiarity with PCB design tools (e.g., Mentor, KiCad)
• Experience with phase-locked loop (PLL) design and applications
• Programming experience in C# or Python
