RF System Modeling Engineer

Job Title

RF System Modeling Engineer

Role Summary

Responsible for electromagnetic (EM) and EMI simulation and analysis for Bluetooth radio products in the BU Short-Range - BLE Radio Development team. Work spans chip, package and PCB levels to inform IC, package, PCB layout and system design decisions and ensure robust performance and EMI/EMC compliance throughout product development.

Experience Level

Mid-level - Experienced engineer. The role expects roughly 5+ years of relevant experience in RF/microwave engineering, EM simulation, or EMI/EMC analysis.

Responsibilities

Key responsibilities include leading simulation work, proposing mitigations, and supporting test correlation.

• Perform advanced EM simulations at chip and PCB levels using industry tools (e.g., Ansys HFSS, Cadence Sigrity, CST, Keysight RFPro).
• Assess and optimize chip- and package-level power distribution networks (PDNs) for noise, integrity, and EMI compliance.
• Simulate and analyze EMI radiation and assess compliance with international standards.
• Collaborate with IC designers, PCB layout engineers, and system architects to provide EM/EMI guidance during development.
• Propose and validate mitigation strategies for EMI/EMC issues at layout and circuit-design levels.
• Prepare and document simulation results, analysis reports, and design recommendations.
• Drive development of EM simulation methods, EMI/EMC standards, and related EDA tool flows.
• Support laboratory EMI/EMC testing and debugging; correlate measurements with simulations.

Requirements

Must-have technical skills and experience; concise list of practical expectations.

• 5+ years of experience in RF/microwave engineering, EM simulations, or EMI/EMC analysis.
• Proven expertise with EM simulation software such as Ansys HFSS, CST Studio Suite, Cadence Sigrity, or Keysight RFPro.
• Familiarity with SPICE-based simulation tools for circuit-level analysis.
• Strong knowledge of PDNs, grounding, decoupling, and related chip/PCB design practices.
• Solid understanding of EMI/EMC theory, measurement techniques, and compliance processes.
• Ability to collaborate across IC, package, PCB and system teams and communicate simulation findings clearly.
• Experience correlating simulations with laboratory EMI/EMC measurements and supporting debug activities.

Nice-to-have:

• Experience developing EM/EMI methodologies or extending EDA tool capabilities.
• Prior work on wireless radio ICs or Bluetooth radio systems.

Education Requirements

Master's or PhD in Electrical Engineering, Electronics, Physics, or a related technical field.
