Join us and make YOUR mark on the World!

Come join Lawrence Livermore National Laboratory (LLNL) where we apply science and technology to make the world a safer place; now one of 2020 Best Places to Work by Glassdoor!

We have an opening for a Nuclear Engineer/Health Physicist who will be responsible for applying commercial and in-house simulation tools for analysis and design in support of our national security missions.  You will work with a team of professional and technical personnel to contribute to the fulfillment of technical  projects which include hazard analysis (e.g., qualitative and quantitative) for the National Ignition Facility (NIF) to assure all operations remain within the limits of NIF’s Safety Basis. You will provide solutions to engineering projects   while providing direction as a key contributor to NIF Radiation Safety and Laser Safety programs. This position is in the Laser Systems Engineering & Operations (LSEO) Division, within the Engineering Directorate.
This position will be filled at either the SES.2 or SES.3 level depending on your qualifications. Additional job responsibilities (outlined below) will be assigned if you are selected at the higher level.
Essential Duties
- Develop a variety of technical documents outlining topics such as moderately complex to complex operating procedures, hazard analyses, and safety basis documents for radiological facilities utilizing broad experience and comprehensive knowledge.
- Provide moderately complex to complex technical guidance  on how equipment or operational changes may impact a facility’s safety basis.
- Participate in research, maintenance, and/or operational planning and evaluation discussions and participate in engineering design reviews.
- Develop radiation transport models of engineering systems using Monte Carlo N-Particle (MCNP) software under limited direction.
- Perform radiation calculations for shielding analyses and neutron activation determination.
- Contribute to the fulfillment of technical projects associated with safety controls/hazard mitigation for Class IV laser systems.
- Remain current on regulatory safety standards and emerging modeling tools.
- Perform other duties as assigned.
In Addition, at the SES.3 Level
- Perform complex analyses using various atmospheric dispersion modelling and/or fire modelling software (such as ALOHA, EPIcode, HOTSPOT, MACCS2, CFAST) as well as hazards analysis (such as HazOps/FMEAs, PrHAs, Hazard Identification, and/or Hazard Evaluations).
- Apply advanced variance reduction techniques for simulations of radiation shielding and detection scenarios that may not be well defined.
- Act as an alternate configured systems manager for radiation shielding and laser safety systems, assure ongoing integrity of associated systems, which are configuration managed due to their potential impact on facility safety working independently and under minimal direction.
- Bachelor’s degree in Nuclear Engineering, Health Physics, or related discipline, or the equivalent combination of previous relevant education and related experience.
- Comprehensive knowledge of and broad experience contributing to the fulfillment of technical projects at nuclear or radiological facilities including elements of engineering research and development, maintenance, planning and/or design review.
- After receiving appropriate training, ability to work comfortably in facilities that contain a wide variety of hazards and hazardous operations (e.g. radiological, chemical, and laser). 
- Broad experience and comprehensive knowledge of  relevant types of safety analyses including modeling skills (e.g., failure analysis, diagnostics, risk and hazard analysis, accident scenario development, source term evaluation, failure mechanism assessment, calculation of accident consequences, evaluation of probability of occurrence).
- Ability to prepare moderately complex to complex technical documents following appropriate   analytical protocols (e.g., safety basis calculations, change control forms, failure mode effects and analyses).
- Broad knowledge of DOE Orders and national standards and regulations as applicable, e.g., 10 CFR 830, Nuclear Safety Management, NRC requirements, commercial codes and standards (e.g., ANSI standards), industry regulations, or engineering practices.
- Broad knowledge of concepts associated with regulations, standards, and engineering practices applicable to nuclear, accelerator, radiological, or chemical facilities.
- Proficient verbal and written communication skills to collaborate effectively in a team environment and present and explain moderately complex to complex technical information.
In Addition, at the SES.3 Level
- Significant experience and advanced knowledge working with complex configuration managed nuclear or safety systems including performing analysis and variance reduction simulation.
- Experience providing precise technical direction associated with complex nuclear, radiological or safety systems.
- Prior experience as responsible individual for development and implementation of radiation safety program (ionizing radiation or laser).
Desired Qualifications
- Master’s Degree in Nuclear Engineering, Health Physics, or closely related field.
- Experience in developing and implementing radiological or laser safety programs.

Pre-Employment Drug Test:  External applicant(s) selected for this position will be required to pass a post-offer, pre-employment drug test.  This includes testing for use of marijuana as Federal Law applies to us as a Federal Contractor.

Security Clearance:  This position requires a Department of Energy (DOE) Q-level clearance.

If you are selected, we will initiate a Federal background investigation to determine if you meet eligibility requirements for access to classified information or matter. In addition, all L or Q cleared employees are subject to random drug testing.  Q-level clearance requires U.S. citizenship.  If you hold multiple citizenships (U.S. and another country), you may be required to renounce your non-U.S. citizenship before a DOE L or Q clearance will be processed/granted.  For additional information, please see DOE Order 472.2

Note:   This is a Career Indefinite position. Lab employees and external candidates may be considered for this position.
