About The Position

AES is seeking an experienced Senior Field Engineer to lead field execution, testing, and commissioning at the National Laboratory of the Rockies (NLR), AES's advanced technology validation and demonstration facility. The role supports evaluation of emerging energy technologies, first-of-kind deployments, and the transfer of innovative solutions from concept to commercial application, in collaboration with subject matter experts in emerging technologies and advanced grid integration. The Senior Field Engineer implements and operates field test programs, commissions new technologies, troubleshoots complex systems, maintains testbed infrastructure, and documents lessons learned for broader AES deployment. The position combines hands-on technical execution, project leadership, vendor collaboration, and innovation-driven problem solving. It is suited to an engineer who enjoys working with new technologies and adapting to evolving requirements. The position is based primarily at the NLR test facility in Arvada, Colorado. Work takes place indoors and outdoors, including in a temperature-controlled jobsite container and active test areas. Some periods may require on-site presence up to five days per week, depending on testing and commissioning schedules. Travel of up to 25% may be required for demonstrations, factory testing, commissioning, and project deployments. The expected salary at commencement is $113,000–$141,525 per year, with annual bonus eligibility. The role includes medical, dental, and vision coverage, life insurance, 401(k) eligibility, and paid time off, including vacation, sick leave, and parental leave.
