Job description

PeraWatt is an early-stage company commercializing a novel class of soft magnetic materials. We’re targeting large and growing markets: data center power, EV charging, and motors. We’re backed by federal and state grants, strategic investors, and a premier startup accelerator.

The Opportunity

We’re hiring a Senior Magnetics Engineer, Power Electronics to lead the full process of turning our novel magnetic materials into high-performance electronic components. You’ll design inductors and transformers from the ground up, characterize their performance, and build the testing and data infrastructure that supports customer adoption. This is a hands-on, high-ownership role at the heart of our commercialization effort.

What You’ll Do

• Design, build, and characterize inductors and transformers using PeraWatt’s soft magnetic materials across target applications to validate material performance under realistic operating conditions
• Build the test and validation infrastructure to benchmark our components against incumbent materials and produce customer-ready data
• Work directly with customers and applications engineers who will use our components in their power converter designs

What You Bring

• 4+ years designing and characterizing magnetic components (inductors, transformers) for high-frequency power electronics
• Strong understanding of electromagnetic theory, magnetic materials properties, and winding techniques for high-frequency components
• Experience with core selection, winding design, conductor selection, loss modeling, and loss characterization
• Proficiency with finite element analysis for magnetics modeling (Ansys, Comsol, or equivalent)
• MS or PhD in Electrical Engineering or a related field

What Sets You Apart

• Customer-facing or applications engineering experience in B2B power electronics
• Familiarity with magnetics for data center power supplies, EV powertrains, or renewable energy inverters
