Facility Engineer

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
