At EEI, we believe in doing things the right way, with excellence, integrity, and genuine care for our people. As an employee-owned company, our People First culture is rooted in trust, accountability, and shared success.

As a Mission Critical Electrical Specialist, you will independently perform the commissioning, testing, and verification of electrical building systems in the field — including power distribution, lighting, wiring, and controls. You will work alongside experienced technical professionals and project stakeholders to ensure critical facility systems operate safely, efficiently, and reliably.

• Produce clear, thorough commissioning documentation in accordance with project requirements and client deliverables.
• Verify installations against design specifications, industry standards, and regulatory requirements to confirm systems are ready for safe and reliable operation.
• Serve as the technical point of contact on-site, communicating project status, technical findings, and recommendations to clients, contractors, and internal project teams.
• Contribute to safe, reliable, and high-quality project execution in a fast-paced mission-critical environment.

• Understanding of MEP systems, controls, and integrated building operations.
• Ability to read and interpret drawings, specifications, sequences of operation, submittals, technical documentation, and system information.
• Ability to independently execute assigned technical activities while collaborating effectively with project teams.
• Strong organizational, troubleshooting, communication, documentation, and teamwork skills.
• Proficiency with Microsoft Office Suite and commissioning documentation tools or project software.
• Strong commitment to ethical standards and confidentiality.
