Senior Electrical Engineer

The Senior Electrical Engineer reports to the Engineering department leader and joins our Battery Energy Storage Systems (BESS) engineering team, responsible for the design, analysis, validation, and deployment of advanced energy storage systems with a strong focus on electrical power systems, control systems, safety compliance, and manufacturing execution. You will work cross-functionally with engineering, manufacturing, quality, and operations teams to deliver safe, reliable, and scalable energy storage solutions. Work is primarily based in the Waterbury, Vermont office, with travel to production facilities and customer sites as needed. NOMAD offers a competitive salary with performance-based incentives, comprehensive medical, dental, and vision benefits, a 401(k) with company match, and professional development opportunities. The following skills, experience, and credentials are what we think are necessary to succeed in this position. If you possess many but not all of these, you are encouraged to apply anyway because you may possess additional skills and experience that could provide value to NOMAD and our customers in ways we have not imagined.
