Senior Nuclear Engineer - NDSE

Mission Support and Test Services, LLC (MSTS) manages and operates the Nevada National Security Site (NNSS) for the U.S. National Nuclear Security Administration (NNSA).  Our MISSION is to help ensure the security of the United States and its allies by providing high-hazard experimentation and incident response capabilities through operations, engineering, education, field, and integration services and by acting as environmental stewards to the Site’s Cold War legacy.  Our VISION is to be the user site of choice for large-scale, high-hazard, national security experimentation, with premier facilities and capabilities below ground, on the ground, and in the air. (See NNSS.gov for our unique capabilities.) Our 2,750+ professional, craft, and support employees are called upon to innovate, collaborate, and deliver on some of the more difficult nuclear security challenges facing the world today.   

• MSTS offers our full-time employees highly competitive salaries and benefits packages including medical, dental, and vision; both a pension and a 401k; paid time off and 96 hours of paid holidays; relocation (if located more than 75 miles from work location); tuition assistance and reimbursement; and more.  
• MSTS is a limited liability company consisting of Honeywell International Inc. (Honeywell), Jacobs Engineering Group Inc. (Jacobs), and HII Nuclear Inc.

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.
   

• Bachelor’s degree in an engineering program accredited by the Accreditation Board for Engineering and Technology (ABET) required for Mechanical and Electrical engineering degrees; or, Calculus-based STEM bachelor’s degree in engineering; or Professional Engineer license; Plus at least 5 years’ relevant experience. 
• BS degree in calculus-based STEM engineering with an MS in Nuclear Engineering preferred. 
• Competency in Monte Carlo (MCNP/SCALE/GEANT) radiation transport codes
• Competency with Neutron Activation and Gamma Activation Analysis techniques 
• Familiarization with gamma spectroscop
