Maintenance Supervisor

NAES•Hubbard, TX

1d•Onsite

About The Position

The APEX Power Co. Project in Hubbard, TX, is undergoing Phase 1 construction and is expected to expand to 1.6 GW. This facility utilizes a variety of generation technologies, including Siemens SGT-800/400 simple cycle turbines, MAN/Everllence 18V51/60G gas reciprocating engines, GE LM6000/LM2500 simple cycle turbines, Pratt & Whitney FT8 simple cycle turbines, and a Battery Energy Storage System (BESS). This diverse mix allows for flexible and reliable power output. Future expansions may incorporate additional GE aero and large frame units (6B, 7FA/7FB/7H) in simple or combined cycle configurations, enabling the plant to efficiently meet fluctuating energy demands and support data center grid reliability. The Maintenance Supervisor at the APEX Power Co. Project will be instrumental in leading and supporting the maintenance team during both the pre-commissioning and operational phases. This role is crucial for ensuring the safe, efficient, and reliable operation of all equipment, encompassing gas turbines, reciprocating engines, battery energy storage systems (BESS), and balance-of-plant systems. Reporting directly to the Maintenance Manager, the Maintenance Supervisor will provide hands-on leadership, coordinate all maintenance activities, offer support during commissioning processes, and cultivate a robust culture of safety and compliance.
