EM Modeling Engineer

Saras Micro Devices•Chandler, AZ

About The Position

Saras Micro Devices is a venture-backed semiconductor startup developing high-performance computing (HPC), package-integrated power delivery solutions for artificial intelligence and advanced networking devices. The EM Modeling Engineer develops electromagnetic models and simulations for capacitors, inductors, embedded passive devices, package structures, and system-level PCB/package power delivery network architectures. The role supports signal and power integrity analysis, customer-specific modeling needs, characterization practices, and product development decisions.

Requirements

Master's degree or PhD in Electrical Engineering.
Experience with electromagnetic simulation.
Experience with HFSS, Maxwell, SIwave, and finite element analysis (FEA).
Experience with resonance and impedance analysis.
Experience with ANSYS Electronics Desktop and LT Spice.
At least 2 years of experience in electromagnetic modeling and simulation.

Nice To Haves

Proficiency in the physics of electromagnetic waves and fields.
Experience with multi-dimensional physics simulation.
Experience with de-embedding techniques.
Experience with COMSOL Multiphysics, Abaqus, Keysight ADS, Python, MATLAB, and JMP.

Responsibilities

Assist and guide the Characterization Team on best practices for test methods, hardware design, calibration, port extension, and de-embedding techniques.
Develop electromagnetic models for capacitors and inductors, including capacitance, inductance, saturation, ESR, ESL, impedance, resonance behavior, S-parameters, and associated SPICE models.
Model power delivery network performance.
Develop equivalent circuit models for embedded passive devices and package structures.
Support signal integrity and power integrity analysis.
Integrate discrete models into system-level simulations for PCB/package power delivery network architectures.
Perform 2.5D and 3D electromagnetic modeling.
Collaborate with and support customer engagement teams on custom customer architecture electromagnetic modeling needs.
Identify and collaborate with external simulation and characterization resources supporting Saras' characterization and simulation efforts.
Generate simulation methodologies, best practices, and standards.
Support technology down-selection and design decisions, and provide simulation-driven recommendations to engineering teams.
Participate in DFMEA and risk assessments.
Support customer design reviews and qualification activities.
Contribute to Design Rule Manuals and product specifications.
