We are looking for Senior RF Test & PCB Design Engineer in San Jose, CA and its a 5 days onsite position. Responsibilities • PCB Development: Lead the schematic entry, component selection, and layout routing optimization for complex RF evaluation boards using Cadence Allegro. • Simulation & Analysis: Perform Signal Integrity (SI) and Power Integrity (PI) simulations. Utilize Ansys HFSS for EM modeling and impedance matching to ensure optimal RF performance. • Hardware Bring-up: Own the board bring-up process, including debugging hardware issues and validating performance against design specifications. • RF Characterization: Utilize lab equipment (VNAs, Spectrum Analyzers, Signal Generators) to perform various RF measurements and verify simulation-to-measurement correlations. Implement Machine Learning (ML) techniques to analyze large datasets and identify performance trends or anomalies. • Cross-functional Collaboration: Work closely with RFIC Design and System Engineering teams to define board requirements and provide feedback on chip-level performance. • Documentation & Data Analysis: Maintain detailed design documentations and test reports for internal and external stakeholders. Collect, review and analyze test data. Requirements MUST HAVES: • Extensive actual PCB and layout design experience (not just as a reviewer) using Cadence Allegro/OrCAD tool. High speed or mmWave experience preferred. • Materials Knowledge: Deep understanding of PCB stack-ups, dielectric materials (e.g., Rogers, Megtron), and manufacturing constraints for high-frequency PCB designs. • Expertise in SI/PI and EM simulations. Requirements • Education: BS or MS in Electrical Engineering or a related technical field. • Experience: 5+ years of hands-on experience in RF PCB design and hardware development. • Tools: Expert-level proficiency in Cadence Allegro/OrCAD and Ansys HFSS (or equivalent EM simulation tools). • RF Fundamentals: Strong knowledge of RF theory, including S-parameters, transmission line theory, matching networks, and de-embedding techniques. • Lab Expertise: Extensive experience with RF test equipment (VNAs, Spectrum Analyzers, Oscilloscopes) and high-speed probing techniques. • Materials Knowledge: Deep understanding of PCB stack-ups, dielectric materials (e.g., Rogers, Megtron), and manufacturing constraints for high-frequency PCB designs. Desirable Skills (Nice to Have) • Automation: Proficiency in Python or C# for developing automated test suites to increase characterization throughput. • Data Science for RF: Experience applying AI/ML models for predictive maintenance of test setups or for signal classification. • Wafer-Level Testing: Experience with manual or semi-automated RF probe stations for on-wafer die characterization.
