The company serves customers through its network of facilities in Asia, Europe, and North America. Rooted in our core values - Focus on the Customer, Ownership & Accountability, Respectfully & Effectively Communicate, and Motivate & Develop People - we foster an environment where diverse perspectives are not only welcomed but celebrated. Everyone can make an impact here. Whether it's improving products, supporting customers, or positively influencing peers and the community, the contributions of our people matter. Shift: The regular hours for this position are day shift. Job Description: FormFactor's RF Products group works closely with leading semiconductor manufacturers to solve advanced test and validation challenges. Our technologies directly enable nextgeneration wireless and highspeed communication systems-including 5G and mmWave modems, ultrahighspeed I/O interfaces, and RF solutions exceeding 100 GHz. We are seeking a Sr. Principal Electrical Design Engineer with deep expertise in RF, highspeed digital, and electromagnetic design. In this senior technical role, you will lead complex design initiatives, drive simulationbased development, mentor junior engineers, and contribute to nextgeneration RF product architectures. Key Responsibilities: HighFrequency / HighSpeed Electrical Design Design advanced RF and highspeed digital physicallayer interconnect structures using simulationdriven design methodologies. Perform systemlevel RF circuit design, including matching networks, transmission line structures, and power delivery architectures. Develop, refine, and optimize electromagnetic (EM) simulation models using industrystandard tools. Modeling, Simulation, and Validation Create detailed EM and circuitlevel models; perform correlation between simulations and laboratory measurements. Conduct powerintegrity simulations of complex powerdelivery networks (both DC and AC domains). Automate simulation workflows to improve repeatability, speed, and data accuracy. HandsOn RF Test & Measurement Lead handson evaluation using VNAs, TDRs, spectrum analyzers, wafer probers, and other highfrequency instrumentation. Mentor engineering teams on measurement best practices, calibration methods, and data analysis. Contribute to the development and refinement of nextgeneration RF calibration methodologies (e.g., SOL, SOLR, SOLT, multiline TRL). Technical Leadership & Collaboration Serve as a senior technical expert, influencing architecture decisions and longterm product roadmaps. Collaborate with crossfunctional teams-including mechanical, process, and product engineering-to optimize product performance and manufacturability. Provide technical mentorship to engineers across the RF product group and broader organization. Preferred Education and Experience: MS or PhD in Electrical Engineering, Physics, or a related field (or equivalent industry experience). 10+ years of electrical engineering experience with significant focus on RF or highspeed digital physicallayer design. Strong proficiency with EM simulation tools such as HFSS, ADS, AWR, and related modeling software. Extensive experience using RF measurement techniques, including VNA, TDR, and waferlevel RF measurements. Background in PCB design and understanding of fabrication constraints and signalintegrity considerations. Familiarity with onwafer RF calibration techniques (SOL, SOLT, SOLR, TRL). Working knowledge of wireless, radar, or digital communications standards (e.g., 5G, WiFi, Bluetooth, PCIe) is a plus. Experience in automation, data processing, or scripting (e.g., Python, MATLAB) is beneficial. Skills: Digital Communications, High Frequency Structure Simulator (HFSS), MATLAB, Python (Programming Language), RF Calibration, RF Measurements Education & Experience: Minimum of 8 years of related experience with a Bachelor's degree; or 6 years and a Master's degree; or a PhD with 3 years experience; or equivalent experience\| Required Pay Range: $115,800.00 - $151,935.00 Pay Range Explained: This role in Beaverton, Oregon pays between $115,800.00 and $151,935.00 per year, depending on your experience, skills, and background.
