The Role

We’re looking for a curious and motivated Electrical Engineering student to join our substation team as an intern. You’ll get hands-on experience on real high-voltage projects, assist with designs and documentation, and learn from engineers who love to teach. No prior design experience needed—just bring your curiosity, teamwork, and eagerness to jump in.

Where You'll Work 

• This internship is based at our Headquarters in St. Louis, MO, and will be an on-site role. The program is expected to run from mid-May through early August.

What Your Day Will Look Like

• Assist with the creation and modification of one-line diagrams, conduit schedules, bills of material (BOM), layouts, relay panel arrangements, existing steel drawings, and cable lists for high-voltage substations (32.4–500 kV).
• ​​​​​​​Support the preparation of engineering and construction estimate documents, including yard layouts, plans, section views, and electrical details.
• Help draft and edit technical specifications for substation equipment such as transformers, circuit breakers, and control houses under the guidance of experienced engineers.
• Collaborate with engineers to support the integration of protection, control, and monitoring systems.
• Apply field mark-ups to project drawings and perform basic engineering calculations (e.g., voltage drop, CT burden, lighting, short circuit) with supervision and mentorship.
• Contribute to a collaborative team environment, with flexibility to assist with other tasks or roles as needed to support project goals.
