About The Position

We’re looking for three (3) Electrical Engineering Interns to support the design and deployment of next-generation energy systems, including battery energy storage systems (BESS), microgrids, and distributed energy resources (DERs).
This is a hands-on learning opportunity for students interested in power systems and real-world energy infrastructure. You’ll work closely with experienced engineers and gain exposure to projects from early design through deployment.
If you’re curious, detail-oriented, and excited to learn how modern energy systems are built and deployed, this role is for you.

Requirements

• Currently pursuing a Bachelor’s or Master’s degree in Electrical Engineering or a related field
• Interest in power systems, renewable energy, or battery energy storage (BESS)
• Basic understanding of electrical engineering fundamentals (circuits, power distribution, etc.)
• Strong attention to detail and willingness to learn
• Ability to work in a fast-paced, team-oriented environment
• Clear communication skills and a proactive mindset

Nice To Haves

• Familiarity with CAD tools or electrical design software is a plus

Responsibilities

• Support electrical design efforts for power systems, including BESS and distributed energy solutions
• Assist in developing and updating single-line diagrams, wiring diagrams, and basic electrical schematics
• Help review electrical components such as panels, switchgear, and protection devices
• Participate in project planning discussions and engineering reviews
• Conduct research on electrical codes (NEC), standards, and emerging technologies
• Support documentation, calculations, and engineering reports
• Assist with inventory tracking, organization, and coordination of electrical components and equipment
• Help maintain accurate inventory records and support material planning for projects
• Assist with site visits, testing, or commissioning activities when applicable
• Collaborate with cross-functional teams including engineering, operations, and product

Benefits

• Hands-on experience working on real-world energy infrastructure projects
• Exposure to battery energy storage systems, microgrids, and distributed energy resources
• Mentorship from experienced engineers and cross-functional leaders
• Understanding of electrical codes, standards, and how they apply in practice
• Insight into how engineering teams operate in a fast-growing startup
