Sandia National Laboratories Reliability Engineer (Early Career) in Livermore, California


This posting will be open for application submissions for a minimum of seven (7) calendar days, including the ‘posting date’. Sandia reserves the right to extend the posting date at any time.


We are seeking a Reliability Engineer.

On any given day, you may be called on to:

  • Apply technical engineering approaches to perform independent reliability analyses and assessments with results reported back to Independent Technical Assessment Management and/or the requesting system or component organization.
  • Team across various organizations (e.g. Nuclear Deterrence, Surveillance Assessment, Quality, Statistical Sciences) and efforts (e.g. Weapon Assessment Teams, Product Realization Teams, Significant Finding Investigation committees, Red Team) to perform reliability assessments and contribute to stockpile sustainment and development (e.g. State of the Stockpile, Annual Assessment, Unsatisfactory Reports, and safety incidents).
  • Participate in investigations of potential defects and/or performance issues to identify the root cause of anomalies and provide reliability impact assessments.
  • Represent the reliability engineering perspective on Weapon Assessment Teams (WAT) to assess the nuclear weapon safety, security, reliability, quality, and surveillance information for each stockpile and development weapon system.
  • Maintain a positive relationship with our customers, the Weapon Systems Departments, the Chief Engineer of Nuclear Weapons, and the Associate Lab Director.
  • Understand reliability failure mechanisms, development program test plans, and surveillance plans to help Product Realization Teams improve the reliability of their designs.
  • Help improve independent assessment and reliability guidance, processes, metrics, and information management tools.


  • Masters degree in Engineering, Applied Mathematics, or a relevant STEM subject area; or equivalent.
  • The ability to acquire and maintain a DOE Q clearance.


  • Strong communication skills, verbal and written.
  • Alert, quick, and responsive, with a positive, self starter attitude.
  • Proven knowledge of technical quality and system engineering principles and standard methodologies.
  • Experience in hazards/safety/failure analysis (e.g. fault tree analysis, failure modes, and root cause analyses).
  • Proven experience or training in nuclear weapons or high-consequence product design, testing, modeling, or assessment.
  • Experience in applying reliability theory and a variety of reliability test methods and analyses across a product’s lifecycle.
  • Familiarity with engineering-level statistical analysis (e.g. probabilistic modeling, margin analyses, Monte Carlo methods).
  • Strong team player with ability to develop trusting, productive working relationships within a multi-disciplinary team.
  • Proven effective time-management skills.
  • Ability to think critically, skeptically, and drive the “so what” and “what if” discussions and analysis.
  • Excellent attention to detail, while considering the big picture when needed (e.g. a component’s reliability as it relates to the system’s).
  • Active DOE L or Q clearance or equivalent with another US government agency (e.g. DOD)

Department Description:

The primary mission of the CA System and Component Reliability Department is to provide reliability analysis services on behalf of the NNSA to the Nuclear Deterrence Program. The department provides independent reliability estimates and assessments of nuclear weapon systems, sub-systems, and components throughout the design-to-retirement life cycle. Assessments performed by this department apply probabilistic reliability models and reliability engineering practices to provide quantitative and qualitative measures that contribute to understanding the impact of design and technology changes. The department supports both development programs for modernization as well as continuing stockpile systems, and strives to provide technically comprehensive, accurate, useful, and timely estimates and assessments. The department provides reliability engineering support for modernization programs to establish sound technical bases to support reliability assertions.

Security Clearance:

Sandia is required by DOE to conduct a pre-employment drug test and background review that includes checks of personal references, credit, law enforcement records, and employment/education verifications. Applicants for employment need to be able to obtain and maintain a DOE Q-level security clearance, which requires U.S. citizenship. If you hold more than one citizenship (i.e., of the U.S. and another country), your ability to obtain a security clearance may be impacted.

Applicants offered employment with Sandia are subject to a federal background investigation to meet the requirements for access to classified information or matter if the duties of the position require a DOE security clearance. Substance abuse or illegal drug use, falsification of information, criminal activity, serious misconduct or other indicators of untrustworthiness can cause a clearance to be denied or terminated by DOE, resulting in the inability to perform the duties assigned and subsequent termination of employment.

EEO Statement:

All qualified applicants will receive consideration for employment without regard to race, color, religion, sex, sexual orientation, gender identity, national origin, age, disability, or veteran status and any other protected class under state or federal law.


This job posting is at the Member level. If a Senior or Principal level employee applies and is selected, they will be moved into the Member level and their salary will be adjusted if necessary. Level promotions are not permitted on this requisition.

Employees must remain in their current position for one year before applying for a new position, with the exception of student interns. Application of this requirement will not supersede the Laboratories’ collective bargaining agreements. See collective bargaining labor agreements for represented bidder eligibility requirements for represented employees.


This Limited Term Employee (LTE) position is a temporary position for one year term, which may be renewed at Sandia's discretion up to a maximum of seven years.

Individuals in LTE positions may bid on regular Sandia positions as internal candidates, and in some cases may be converted to regular career positions during their term if warranted by ongoing operational needs, continuing availability of funds, and satisfactory job performance.
