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 (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.
