About the company:
Last Energy is a nuclear energy company that designs, builds, owns, and operates small modular reactors (SMRs) for industrial and commercial customers. The company's flagship product, the PWR-20, is a 20 MWe pressurized water reactor that is fully modular and factory-produced, enabling faster and more cost-effective deployment than traditional nuclear power plants. Last Energy serves as a behind-the-meter independent power producer, supplying reliable baseload electricity to energy-intensive industries including data centers, metals production, food and beverage, pulp and paper, chemicals, and cement manufacturing.
The company's mission centers on making nuclear power radically simpler and more accessible by removing the burden of development, financing, and operations from customers through a power purchase agreement model. This approach aligns nuclear energy deployment with the urgent need for resilient, low-carbon power, particularly as demand from AI infrastructure and industrial growth accelerates. Last Energy's use of proven reactor technology combined with proprietary steel containment systems is designed to streamline licensing and reduce construction timelines.
Last Energy represents a new generation of nuclear developers focused on decarbonizing hard-to-abate industrial sectors with firm, emissions-free power. By standardizing and modularizing the entire plant through factory manufacturing, the company aims to bring predictable costs and schedules to a sector historically challenged by both, positioning SMRs as a practical climate solution at commercial scale.
Last Energy seeks a full-time Facility Engineer to serve as the engineering system owner of the PWR-5 Reactor facility. This role is responsible for the complete configuration, maintenance, and change management program for the PWR-5 — acting as the authoritative bridge between engineering and operations and ensuring the facility meets all applicable DOE requirements. The Facility Engineer will maintain an up-to-date, rigorous picture of the facility at all times, own the Master Equipment List, and develop and sustain the maintenance management program that keeps the PWR-5 operating safely and in compliance. This is a technically demanding, high-ownership role at the center of Last Energy's reactor deployment program.
Key Duties & Responsibilities
- Serve as the single technical owner of the PWR-5 facility configuration — maintaining an accurate, continuously updated record of all systems, structures, and components
- Build, own, and maintain the Master Equipment List (MEL) for the PWR-5 facility, ensuring completeness, accuracy, and version control at all times
- Develop and manage a comprehensive maintenance management plan covering preventive, corrective, and predictive maintenance across all facility systems
- Evaluate, document, and justify proposed changes to facility configuration, systems, or components — ensuring all modifications are properly reviewed, validated, and approved before implementation
- Act as the primary technical liaison between the engineering and operations teams, ensuring operational realities are reflected in engineering documentation and vice versa
- Support DOE compliance requirements related to facility configuration management, change control, and maintenance program documentation
- Conduct regular facility walkdowns and system reviews to identify discrepancies between as-built conditions and design documentation, and drive resolution
- Coordinate with vendors, contractors, and internal teams on facility modifications, equipment procurement, and maintenance activities
- Maintain a running log of all facility configuration changes, open action items, and maintenance history, providing regular status updates to engineering and operations leadership
- Support incident reviews, root cause analyses, and corrective action programs as they relate to facility systems and equipment
Qualifications
- Bachelor's degree in mechanical, nuclear, electrical, or systems engineering, or a related field required
- 10+ years of experience in operations engineering, plant engineering, or a related role, preferably in a nuclear, power generation, or highly regulated industrial environment
- Strong systems-level thinking with demonstrated ability to understand and document complex system interactions and interdependencies
- Hands-on plant or facility experience — must be comfortable working in and around operating or construction-phase industrial facilities
- Meticulous attention to detail; proven track record of maintaining rigorous configuration and equipment records in a high-stakes environment
- Familiarity with configuration management principles, change control processes, and maintenance management programs
- Experience working within DOE, NRC, or equivalent regulatory frameworks is highly preferred
- Strong written communication skills; ability to produce clear, audit-ready technical documentation
- Ability to work independently, manage competing priorities, and drive tasks to closure without close supervision
- Willingness to travel frequently to the RELLIS campus and other facility sites as required
