Plant Engineer Jobs in Tennessee

OPERATION & MAINTENANCE ENGINEER (POWER PLANT)

As an Operation & Maintenance Engineer, you will keep SpaceXSI's on-site power plant running. The plant supplies power for high-density AI supercomputing facilities in the Memphis and Southaven area, and it has to stay online 24/7.

You will work across gas turbines and generators, balance-of-plant, fuel gas and process/fluid systems, water, compressed and instrument air, HVAC and cooling, and plant electrical systems. The turbine fleet is several different manufacturers. You are expected to be proficient on every type on site, not specialized in one OEM. You will troubleshoot equipment, direct contractors, and use AI to simplify how the plant is operated and maintained. Your schedule flexes, including nights, weekends, holidays, and callouts, so the plant always has engineering coverage. This is a full-time, on-site role in the Memphis region.

RESPONSIBILITIES:

• Provide operation and maintenance engineering support for the multi-manufacturer gas turbine fleet, generators, balance-of-plant, process and fluid systems, and plant electrical systems, including protection, e-houses, blackstart, and switching.
• Be proficient across all turbine types on site and apply that knowledge to troubleshooting, maintenance, and operating decisions.
• Flex shifts and work hours, including nights, weekends, holidays, and callouts, to maintain 24/7 engineering coverage.
• Troubleshoot trips, alarms, and equipment failures with the shift team and return the plant to service.
• Direct contractors: define the work, set when it is done, and confirm it is completed safely and correctly.
• Use AI to streamline and simplify engineering, operating, and maintenance work.
• Own reliability on assigned systems: bad-actor elimination, root-cause investigations, and corrective actions.
• Write and maintain the engineering plans and procedures the plant is being stood up on, including operating, maintenance, and switching and isolation instructions.
• Manage the critical-parts list so the right parts are identified, stocked, and ready.
• Build and maintain the preventive and predictive maintenance program in the CMMS, including tasks, frequencies, and as-found/as-left records.
• Support outage planning and execution, and support start-up, shutdown, commissioning, and turnover of new generation and balance-of-plant systems.
• Apply SpaceXAI safety standards in the field, including LOTO, NFPA 70E / arc-flash, confined space, and hot work. Stop work when conditions are unsafe.

BASIC QUALIFICATIONS:

• Bachelor's degree in mechanical, electrical, or other engineering discipline.
• 3+ years of operation or maintenance engineering experience in a power plant, generating station, or other high-reliability industrial facility.

PREFERRED SKILLS AND EXPERIENCE:

• Experience with gas turbines from more than one manufacturer, plus balance-of-plant, fuel gas, water, compressed air, and plant electrical systems.
• Willingness to work rotating or flexible shifts, including nights, weekends, holidays, and on-call, to support 24/7 plant coverage.
• Experience using AI tools to streamline or simplify engineering, maintenance, or operating processes.
• Experience directing contractors, including assigning work and setting the schedule.
• Experience managing critical-parts lists.
• Experience with engineering planning and procedure writing.
• Working knowledge of P&IDs, single-line diagrams, electrical schematics, protection, and switching.
• Experience with LOTO and NFPA 70E / arc-flash practices.
• Experience with a CMMS, including preventive maintenance, work orders, and equipment history.
• Experience supporting outages, commissioning, or root-cause investigations on power plant equipment.

ADDITIONAL REQUIREMENTS:

• Willingness to be in the plant and to perform hands-on work in all environments (heat, cold, rain), in tight quarters or at heights.
• Remain focused while working in hazardous environments, while wearing appropriate PPE.
• Must be able to lift up to 25 lbs unassisted.
• Lifting, standing, climbing, bending, grasping, sitting, pulling, pushing, stooping, stretching, and carrying are generally required to perform the functions of this position.
• Must be able to work on-site at the power generation facility, with potential travel to other SpaceXAI sites.
• Valid driver's license.
