What are the responsibilities and job description for the Energy Engineer position at Leidos?
Description
Leidos Engineering LLC is a premier national engineering-based management consulting firm. We are seeking an experienced and motivated candidate to join our team in Peoria or St. Louis as an Energy Engineer. The position is ideal for a person with excellent technical skills and energy engineering experience with experience in calculating energy saving estimates, energy auditing, and communicating technical issues within the project team while working closely with contractors, suppliers, architects, and project engineers.
Location: This position is fully remote. Ameren Illinois and Leidos believe it is very important to provide employment opportunities to the utility ratepayers that reside in Illinois. Therefore, there is a strong preference for the candidate to reside in the Ameren Illinois service territory (https://www.ameren.com/illinois/company/about-ameren/service-territory (roughly the southern two-thirds of Illinois)).
