Our diverse portfolio of assets is owned by ArcLight Capital Partners, a leading middle-market, value-added infrastructure investment firm that owns assets across the power, renewables, strategic gas, battery storage, and transformative infrastructure sectors. ArcLight has invested over $28 billion in equity capital across 125 transactions totaling approximately $80 billion in enterprise value. ArcLight has assembled a best-in-class leadership team at AlphaGen to manage over 14,000 megawatts of power infrastructure across four RTO markets (PJM, NYISO, ISONE, and CAISO). This highly experienced senior management team has a proven track record of strategic, operational, and commercial success and is focused on value creation while managing risk. AlphaGen oversees one of the largest domestic, independent power portfolios, with nearly $2 billion in annual revenue. Reporting to the Fleet Overall Program Lead, the Fleet Thermal Engineer to provide fleet-wide engineering support for thermal systems, with primary emphasis on boiler performance, high-energy piping reliability, and steam cycle equipment. The role supports plant operations, maintenance, and outage planning by resolving thermal performance and equipment reliability issues and implementing engineering solutions that enhance efficiency and safe operation. Responsibilities include Balance of Plant thermal system support—covering condensers, cooling towers, and air-cooled condensers—and leadership in the implementation and continuous improvement of the fleet Boiler Program. The Fleet Thermal Engineer works closely with fleet engineering, plant operations, maintenance teams, and third-party vendors to ensure consistent application of fleet standards, reliability programs, and thermal engineering best practices.

Requirements

Minimum 7 years of relevant engineering experience in the power generation industry, with 10+ years preferred.
Bachelor's degree in Mechanical Engineering preferred; Electrical, Industrial, or related Engineering may be considered with relevant thermal and steam cycle experience.
Demonstrated experience with boilers or HRSGs, high energy piping, condenser performance, steam cycle systems, outage support, and reliability improvement programs in utility, power generation, or comparable industrial environments.
Self-starter and motivated individual who takes initiative and demonstrates full ownership of activities required to fulfill the role.
Strong analytical and problem-solving skills with the ability to manage multiple priorities across fleet sites.
Ability to work collaboratively with plant personnel, engineering, and operations leadership to find practical solutions to problems encountered.
