Senior RF Test & PCB Design Engineer

Responsibilities

• Lead the schematic entry, component selection, and layout routing optimization for complex RF evaluation boards using Cadence Allegro.
• Perform Signal Integrity (SI) and Power Integrity (PI) simulations.
• Utilize Ansys HFSS for EM modeling and impedance matching to ensure optimal RF performance.
• Own the board bring-up process, including debugging hardware issues and validating performance against design specifications.
• 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.
• Work closely with RFIC Design and System Engineering teams to define board requirements and provide feedback on chip-level performance.
• Maintain detailed design documentations and test reports for internal and external stakeholders.
• Collect, review and analyze test data.

Requirements

• Extensive actual PCB and layout design experience (not just as a reviewer) using Cadence Allegro/OrCAD tool.
• High speed or mmWave experience preferred.
• Expertise in SI/PI and EM simulations.

Education

• BS or MS in Electrical Engineering or a related technical field.
• 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).
• Strong knowledge of RF theory, including S-parameters, transmission line theory, matching networks, and de-embedding techniques.
• Extensive experience with RF test equipment (VNAs, Spectrum Analyzers, Oscilloscopes) and high-speed probing techniques.
• Deep understanding of PCB stack-ups, dielectric materials (e.g., Rogers, Megtron), and manufacturing constraints for high-frequency PCB designs.

Desirable Skills

• 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.
• Experience with wafer-level testing, including manual or semi-automated RF probe stations for on-wafer die characterization.
