Original job description

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 as a Senior 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.

Primary Responsibilities:

Reviewing technical energy efficiency applications for incentives and rebates for Ameren Illinois electric and natural gas customers
Review different types of energy using systems within the industrial and/or commercial markets (HVAC, Lighting, compressed air systems, energy management systems, etc)
Research technology changes to support improvements to the energy efficiency program and provide solutions for implementation improvements
Maintain working knowledge of the Illinois Technical Reference Manual and associated energy efficiency concepts.
Review existing energy savings methods for quality control/improvements
Utilize independent judgment to verify technical requirements are met throughout various energy savings initiatives
Coordinate & provide guidance to supporting teams regarding energy efficiency programs

Basic Qualifications

Bachelor’s degree in engineering, Economics, Business Administration or related, with six plus (6+) years of relevant experience
Prior experience in energy efficiency or similar technologies.
Proficiency with Microsoft Office Products, especially Microsoft Excel
Must be able to work cooperatively on a technical team, along with working with non-technical team members.
Must have well developed communication skills and be able to express thoughts and ideas clearly and concisely in both verbal and written format.
Strong planning, organization, time management, and team-building skills with demonstrated ability to make unanticipated changes to production deliverables required

Preferred Qualifications

CEM or LEED certification
Understanding of utility-offered products or services
Focus on being able to see things through customer’s eyes to improve customer experience and satisfaction
Experience working with commercial contractors
Experience with Advanced Lighting and Controls, Commercial HVAC, Compressed Air, or Industrial Process technology
Familiarity with the International Energy Conservation Code (IECC) or ASHRAE Efficiency Standards
Experience with COMcheck, eQuest, Trane TRACE™, or Carrier HAP
Experience with Customer Relationship Management (CRM) software
Experience in the development and implementation of standards, procedures and guidelines for a process-oriented position.
Excellent English oral and written communication skills.

Job Location: This position is a remote position. 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 located in 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).

Travel may also be required to the Peoria, IL and/or Collinsville, IL offices on a periodic basis.

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.

If you're looking for comfort, keep scrolling. At Leidos, we outthink, outbuild, and outpace the status quo - because the mission demands it. We're not hiring followers. We're recruiting the ones who disrupt, provoke, and refuse to fail. Step 10 is ancient history. We're already at step 30 - and moving faster than anyone else dares.

Original Posting:

September 21, 2026

For U.S. Positions: While subject to change based on business needs, Leidos reasonably anticipates that this job requisition will remain open for at least 3 days with an anticipated close date of no earlier than 3 days after the original posting date as listed above.

Pay Range:

Pay Range $73,450.00 - $132,775.00

The Leidos pay range for this job level is a general guideline onlyand not a guarantee of compensation or salary. Additional factors considered in extending an offer include (but are not limited to) responsibilities of the job, education, experience, knowledge, skills, and abilities, as well as internal equity, alignment with market data, applicable bargaining agreement (if any), or other law.

Securing Your Data

Beware of fake employment opportunities using Leidos’ name.

If you believe you are the victim of a scam, contact your local law enforcement and report the incident to the U.S. Federal Trade Commission (https://reportfraud.ftc.gov/#/) .
