This exciting position offers a unique career opportunity for a dynamic person with excellent outreach, industrial sales, communication, and organizational skills to influence leading-edge energy efficiency projects within a creative team environment.

Location: This position is fully remote. Ameren Illinois and Leidos believe it is very important to provide employment opportunity to the utility ratepayers that reside in Illinois. Therefore, there is strong preference for the successful candidate to be living no more than 60 miles from the Ameren Illinois service territory - https://www.ameren.com/illinois/company/about-ameren/service-territory (roughly the southern two-thirds of Illinois). The Ameren Illinois service territory includes several large to mid-size communities such as Galesburg, Quincy, Peoria, Bloomington-Normal, Champaign-Urbana, Danville, Decatur, Springfield, Charleston-Mattoon, Effingham, Mt. Vernon, Marion, Carbondale, and Metro East (Belleville, O'Fallon, Granite City, Edwardsville, Alton, Collinsville).

• Perform sector market analysis and provide input in developing/modifying programs to meet changing market needs
• Coordinate and educate customers, and provide training for internal and external clients on energy related opportunities
• Work closely with commercial and industrial customers, contractors, suppliers, and engineers to encourage energy efficiency practices in both existing and new facilities
• The Energy Advisor will report to the Field Energy Advisor Manager.

Essential Duties and Responsibilities:

• Work directly with building owners, architects, and engineers to understand energy conservation and decarbonization goals.
• Manage a high-volume portfolio of projects at various stages of the consulting process.
• Perform energy simulation analyses and deliver model results efficiently.
• Prepare detailed reports on energy modeling, decarbonization results, and design recommendations.
• Communicate energy conservation measures to both technical and non-technical team members to support informed design decisions.
• Collaborate with project managers to ensure high-quality results and deliverables.

Nice to Haves (but Not Required):

• Sales Experience: While not a sales role, having a background in sales can be beneficial in understanding customer needs and project development.
• Professional Engineer License: Although not required, a PE license could add value to your technical expertise.
• Field Consulting: If you enjoy dynamic environments and site visits, this role will suit you. However, it's not ideal for those who prefer stationary office work.
• Specialized Equipment Knowledge: Broad technical skills are preferred, but specific expertise in certain equipment or systems can be helpful.
• Change Management Experience: Being comfortable with change and adapting quickly will be a plus in this ever-evolving industry.

Although this role will primarily support the Ameren Illinois Energy Efficiency Program, Leidos will be the employer of the person, Ameren Illinois does not take any role in selecting the person for employment, and Ameren Illinois will not have any role in managing the work performed by the person.
