Empower Semiconductor
Overview
Empower Semiconductor is seeking a highly skilled Magnetics System Engineer to join our semiconductor power electronics team. This role focuses on the design, modeling, development, and integration of magnetic components—such as inductors, transformers, and magnetic materials—used in semiconductor-based power systems (e.g., DC-DC converters, power modules, and high-frequency systems). You will work closely with IC design, packaging, thermal, and system architects to optimize magnetic components for performance, reliability, and cost. Key Responsibilities
Design & Development:
Design custom magnetic components (transformers, inductors, EMI filters) for high-frequency power conversion systems (from kHz to MHz). Select and specify magnetic materials (ferrite, powdered iron, amorphous, nanocrystalline) suitable for application requirements. Work with PCB layout teams to ensure optimal integration of magnetic components. Develop magnetics models (analytical and finite-element) for accurate performance prediction.
Simulation & Modeling:
Use simulation tools (e.g., ANSYS Maxwell, MATLAB, SPICE, Simplorer) to model magnetic fields, losses, saturation, and thermal behavior. Support co-simulation with system-level simulators to ensure system stability and EMI compliance.
Testing & Validation:
Develop and execute test plans for magnetic components in prototype and production systems. Analyze failure modes and reliability data to improve magnetic designs. Collaborate with test engineering teams to characterize components under real-world operating conditions.
Cross-functional Collaboration:
Partner with IC designers, mechanical engineers, and system architects to optimize overall power delivery system. Provide magnetic component guidance for package engineers and PCB layout designers. Interface with suppliers and manufacturers for custom component development.
Qualifications
Required:
B.S. in Electrical Engineering, Power Electronics, or related field (M.S. or Ph.D. preferred) 3+ years of experience in magnetics design for power systems or semiconductor products Deep understanding of electromagnetic theory and magnetic material properties Experience with design and fabrication of planar and discrete magnetics Proficient in simulation tools (e.g., Maxwell, COMSOL, PLECS)
Preferred:
Knowledge of EMI/EMC standards and filter design Experience in thermal management of magnetic components Knowledge of semiconductor packaging and integration trends (e.g., power modules, SIP, MCM)
Seniority level
Mid-Senior level Employment type
Full-time Job function
