Hardware Engineer - Magnetics Design Focus

Hardware Engineer – Magnetics Design Focus

The devices we make at SEL are embedded in the power grid and critical infrastructure. They prevent blackouts, control processes, and reliably communicate critical information. They make outages safer and shorter in duration; they monitor infrastructure to prevent outages and record critical data to inform decisions; and they add cybersecurity, automation, and communication.

SEL products and technologies are critical for the safe, reliable operation of power systems and critical infrastructure around the world, so our products are built with the highest-quality components in SEL facilities by SEL employees. As a Hardware Engineer in Research and Development, you'll specify, design, and test these devices and support them over the long lifetime of SEL products in the same place where those products are manufactured.

As a Hardware Engineer with an electromagnetics design focus, a typical day might include the following:

- Analyze, design, develop, prototype and test custom magnetic components. Conducts moderate to complex design reviews to demonstrate product and circuit robustness.

- Design and optimize magnetic current sensors including CTs (instrument class, protection class) and Rogowski Coils for various frequency and current ranges.

- Perform analytical calculations and electromagnetic simulations (e.g., using FEM tools such as ANSYS Maxwell or similar).

- Specify magnetic core materials, winding configurations, insulation systems, and encapsulation methods.

- Develop and execute test plans to validate accuracy, linearity, bandwidth, thermal behavior, and environmental compliance.

- Develops hardware specifications and prepares system level specifications.

- Provides and maintains accurate project plans. Manages and/or leads hardware projects of moderate complexity. Coordinates engineering activities with purchasing and manufacturing.

- Mentors and directs the efforts of associate engineers and technicians.

- Collaborate with mechanical and manufacturing engineers to ensure sensor designs are cost-effective and manufacturable.

- Interface with firmware and hardware teams to integrate sensors into complete systems (e.g., power meters, relays, fault indicators).

- Prepare design documentation, including schematics, drawings, and test reports.

- Ensure compliance with relevant standards (e.g., IEC 61869, IEEE C57.13, UL, CE, RoHS).
