MSTS is required by DOE directive 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 offered employment with MSTS are also 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. In addition, Applicants for employment must be able to obtain and maintain a DOE Q-level security clearance, which requires U.S. citizenship, at least 18 years of age. Reference DOE Order 472.2, “Personnel Security”. 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.

Department of Energy Q Clearance (position will be cleared to this level). Reviews and tests for the absence of any illegal drug as defined in 10 CFR Part 707.4, “Workplace Substance Abuse Programs at DOE Sites,” will be conducted.  Applicant selected will be subject to a Federal background investigation, required to participate in subsequent reinvestigations, and must meet the eligibility requirements for access to classified matter. Successful completion of a counterintelligence evaluation, which may include a counterintelligence-scope polygraph examination, may also be required. Reference 10 CFR Part 709, “Counterintelligence Evaluation Program.”

MSTS is an Equal Opportunity Employer. All qualified applicants will receive consideration for employment without regard to race, color, religion, sex, sexual orientation, national origin, disability, veteran status or other characteristics protected by law. MSTS is a background screening, drug-free workplace.

Annual salary range for this position is: $99,340.80 to $149,011.20.

Starting salary is determined based on the position market value, the individual candidate education and experience and internal equity. 

The Nevada National Security Site (NNSS) is seeking outstanding candidates for a Nuclear Engineer position supporting the Neutron Diagnosed Subcritical Experiment (NDSE) project to design, develop, operate, and maintain dense plasma focus (DPF) neutron generating pulsed power machines in North Las Vegas, Area 11, and primarily the Principal Underground Laboratory for Subcritical Experiments (PULSE) facility to interrogate and diagnose explosively driven physics packages as part of a series of subcritical experiments (SCEs) in the interest of ensuring the safety, security, and reliability of our nation’s nuclear weapon stockpile.
In this role, the candidate will be expected to apply nuclear and electrical engineering concepts and techniques to support the Z-pinch Experiment Underground System (ZEUS) and all its associated subsystems and diagnostics systems, while also collaborating closely with other pulsed power testbed teams such as Cygnus and Scorpius to develop and employ common engineering documentation and fielding methodologies across multiple experiment testbeds where applicable. 
 

Key Responsibilities

• Collaborate with multiple internal and external organizations to field and characterize the DPF machine in Area 11 in preparation for installation and operation at the PULSE facility.
• Work as part of a team of engineers, physicists, and technologists from the weapons labs and the NNSS to install and operate ZEUS and possibly Scorpius, along with associated pulsed power diagnostics systems and detector systems on SCEs at the PULSE facility.
• Collaborate with a team which includes scientists, engineers, technicians, postdocs and students from the NNSS, Sandia National Laboratory (SNL), Lawrence Livermore National Laboratory (LLNL) and Los Alamos National Laboratory (LANL) to ensure readiness of all phases of ZEUS operations at PULSE, from testing and characterization in NLV and Area 11, to delivery, installation, operations, and maintenance as a primary diagnostic system for SCEs at PULSE.
• Will initially work under the supervision of more experienced personnel but will eventually provide technical direction for testing and characterization of pulsed power neutron generator systems and machine diagnostics systems for the DPF machines fielded in North Las Vegas, Area 11, and at PULSE.
• Supports and develops electrical systems for prompt and delayed radiation detection equipment.
• Supports and develops timing and triggering systems in support of ZEUS and SCE experiments.
• Development of system documentation and testing procedures
• Development of system integration drawings 
• Perform data analysis and document results.
• Contributes to strategies, reports, and technical proposals.
• Serves as an internal subject matter expert and is recognized by their colleagues as such.
