Shift Electrical System Engineer; Nuclear Facilities Engineer

What You Will Do

The Plutonium Facilities Engineering - Auxiliary Systems (PFE-AUX) facility engineering group at Los Alamos National Laboratory (LANL) is seeking an Electrical System Engineer specializing in low voltage systems and instrumentation & controls. 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.

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 will be assigned if the candidate is hired at the higher level.

At this level the selected applicant will support PFE and LANL's mission by serving as a subject matter expert in nuclear facility electrical engineering, with emphasis on low voltage systems and instrumentation and controls within and around the plutonium facility.

Responsibilities include all aspects of electrical engineering in nuclear facilities, including electrical safety, power quality, power monitoring, and critical power reliability and redundancy. The engineer supports facility modifications, new structure and equipment development, demolition activities, installations, upgrades, and repairs.

Engineering duties 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. The role contributes to integrated, full system design solutions through mentorship, technical leadership, and coordination across teams.

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.

In addition to the responsibilities of lower level engineers, the Nuclear Facilities Engineer 3 serves as a senior technical authority for nuclear facility electrical 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 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.

Key responsibilities include interpreting regulatory requirements, resolving conflicts between codes and standards, translating requirements into executable engineering direction, leading complex, multidisciplinary design efforts, providing final technical review and approval for significant modifications, new installations, and safety‑related system changes.

The Nuclear Facilities Engineer 3 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.

Additional duties include mentoring and developing junior and mid‑level engineers, establishing technical expectations, and…
