Shift Fire Protection System Engineer ; Nuclear Facilities Engineer

What You Will Do

This position will be filled at either a Nuclear Facilities Engineer 2 or 3 level, depending on the skills of the selected candidate. Additional job responsibilities (outlined below) will be assigned if the candidate is hired at the higher level.

The Plutonium Facilities Engineering - Auxiliary Systems (PFE-AUX) facility engineering group at Los Alamos National Laboratory (LANL) are seeking a Fire Protection Engineer. Put your engineering talents to good use by joining our world-class Engineering team! Our workforce thrives in an environment that values creativity and problem solving to overcome and prevail over challenges. This is your chance to make a real difference while working on important systems directly impacting national security.

At this level the selected applicant will support PFE and LANL's mission by serving as a subject matter expert in nuclear facility fire protection engineering, with emphasis on fire protection systems within and around the plutonium facility. This role is responsible for all aspects of fire protection in nuclear facilities, including active systems (fire alarm systems, public address systems, fire extinguishing / suppression systems, etc.),

passive systems (fire-rated assemblies, fire-rated doors and windows, etc.), life safety systems, life safety assessments, and combustibles assessments. The engineer supports facility modifications, new structure and equipment development, demolition activities, installations, upgrades, and repairs. Engineering responsibilities include performing and reviewing complex engineering studies such as short circuit analysis, device coordination, equipment sizing, exterior lighting design, fault current calculations, and arc flash analysis for both medium and low voltage systems.

Engineers at this level will qualify as a Cognizant System Engineer on one or more Vital Safety Systems that support LANL Nuclear Facilities. In addition to technical execution, the Nuclear Facilities Engineer 2 works collaboratively with junior and senior engineers across disciplines, including fire protection, structural, mechanical, and electrical engineering. This role contributes to integrated, full system design solutions through mentorship, technical leadership, and coordination across teams.

The position is intended for engineers specializing in low voltage systems and instrumentation and controls who demonstrate increasing independence, technical depth, and leadership in complex nuclear facility environments.

The candidate can either be a qualified Fire Protection Engineer or another engineering discipline (such as a Mechanical Engineer) with demonstrated experience or willingness, and ability to support Fire Protection systems.

In addition to the responsibilities of lower level engineers, the Nuclear Facilities Engineer 3 serves as a senior technical authority for nuclear facility fire protection engineering within plutonium and other nuclear facilities. This role provides strategic leadership, technical governance, and decision making authority for complex, high consequence engineering systems, with emphasis on low voltage systems and instrumentation and controls. The engineer at this level is responsible for ensuring that nuclear facility engineering programs are effectively and efficiently implemented in accordance with the Nuclear Safety Management Rule, applicable DOE Orders and Standards, American Nuclear Society Standards, national consensus Codes and Standards, recognized quality standards, Laboratory requirements, and federal, state, and local regulations.

This includes interpreting regulatory requirements, resolving conflicts between codes and standards, and translating requirements into executable engineering direction. The Nuclear Facilities Engineer 3 leads complex, multi discipline design efforts and provides final technical review and approval for significant modifications, new installations, and safety related system changes. This role frequently interfaces with facility management, safety basis personnel, Cognizant System Engineers, and external oversight organizations to defend technical positions and ensure regulatory compliance.

Engineers at this level will qualify as a Cognizant System Engineer on one or more Vital Safety Systems that support LANL Nuclear Facilities. The Nuclear Facilities Engineer 3 mentors and develops junior and mid level engineers, establishes technical expectations, and drives continuous improvement in engineering quality, safety, and reliability across nuclear facilities. This position requires a high level of independent judgment, accountability for technical risk, and the ability to influence outcomes at the program and institutional level.
