  • Correlate simulation results with laboratory measurements (VNAs, anechoic chamber measurements, near-field probes) and iterate models to improve accuracy and predictive capability.
  • Conduct EMI/EMC investigations and mitigation strategies, including shielding, filtering, cable routing, and enclosure modifications informed by simulation and test data.
  • Develop and maintain simulation libraries, reusable models, and best-practice templates to accelerate project delivery and ensure consistency across product lines.
  • Implement mesh convergence studies and uncertainty quantification to provide confidence bounds on simulation predictions used in risk assessments and design decisions.
  • Work cross-functionally with antenna engineers, PCB designers, mechanical engineers, and software teams to integrate EM constraints into product architecture early in the design cycle.
  • Automate simulation workflows using scripting (Python, MATLAB, or vendor APIs) for batch studies, parametric optimization, and cloud/cluster job submission to improve throughput.
  • Perform thermal-EM co-simulation and evaluate the impact of temperature-dependent material properties on RF performance when applicable.
  • Provide technical leadership on EMC compliance requirements (FCC, CE, CISPR, RTCA DO-160, ISO standards) and support documentation for regulatory filings and design reviews.
  • Mentor junior engineers on simulation techniques, solver selection, meshing strategies, and measurement correlation to build internal EM capability.
  • Create clear, actionable reports and presentation materials that translate complex EM simulation results into design recommendations for product managers and stakeholders.
  • Investigate and resolve complex field coupling issues (antenna-antenna, antenna-device interaction, cable radiation) using full-wave 3D models and circuit-level co-simulation.
  • Evaluate and recommend new EM tools, solver engines, and compute infrastructure (GPU, cloud) aligned with team needs and cost/benefit analysis.
  • Manage and prioritize multiple simulation tasks across concurrent projects, ensuring simulation deliverables meet program milestones and quality expectations.
  • Participate in exploratory R&D projects to push the boundaries of EM modeling (metamaterials, adaptive antennas, mmWave/THz systems) and publish findings internally or externally where appropriate.
  • Support design reviews, design-for-manufacturing (DFM) assessments, and supplier engagements by providing EM-focused fabrication tolerances, test plans, and recommended inspection criteria.
  • Troubleshoot field failures and support root-cause analysis for product incidents where electromagnetic interactions are suspected contributors.
  • Lead parametric tolerance studies and yield analysis to quantify manufacturability impacts on RF/antenna performance and support statistical design decisions.

Secondary Functions

  • Support cross-team data requests by producing simulation datasets, metadata, and documented assumptions for ML/AI models or digital twins.
  • Contribute to the organization's EM modeling standards, naming conventions, and simulation governance practices.
  • Collaborate with manufacturing and test engineering to translate simulation scenarios into test procedures and acceptance criteria.
  • Participate in Agile ceremonies, contribute EM work estimates for sprints, and align simulation deliverables with product backlog priorities.
