EM Modeling Engineer

Electromagnetic Modeling and Simulation Engineer

Company: Saras Micro Devices

Location: Atlanta, Georgia

Reports to: Manager, Product Development Engineering

About the Role

Saras Micro Devices is a venture-backed semiconductor startup. We are developing high-performance computing (HPC), package-integrated, power delivery solutions for artificial intelligence (AI) and advanced networking devices. We’re looking for an R&D Engineer I to support manufacturing process development, process integration, prototype fabrication, engineering experiments, and manufacturing readiness throughout the product development lifecycle.

This role supports the development and optimization of materials and process flows, plans and executes engineering trials, collects and analyses process, metrology, yield, and reliability data, and helps troubleshoot process and equipment issues. The R&D Engineer I develops technical documentation, supports equipment qualification and prototype evaluation, and works closely with engineers, technicians, operations personnel, suppliers, and other cross-functional partners to advance development work from laboratory-scale experimentation through pilot manufacturing and production readiness.
