Neutron Diagnosed Subcritical Experiment (NDSE) Scientist I/II

The Neutron Diagnosed Subcritical Experiment (NDSE) program is seeking outstanding scientists at various career stages (Scientist I and Scientist II) to work with ESCE team to support installation, commissioning, and technical maturation, the world's newest and most advanced linear induction accelerator, Scorpius. Scientists will contribute to NDSE program advancing high-power dense plasma focus, neutron generating performance. Responsibilities span experimental activities (e.g. diagnostics developments), modeling and simulations, data analysis, and cross-disciplinary collaboration with pulsed power, target, controls, and operation teams in high-consequence DOE environment. Successful candidates will work within a collaboration between the Nevada National Security Site, Los Alamos National Laboratory, Livermore National Laboratory, and Sandia National Laboratory to prepare the DPF for state-of-the-art experiments and to solve challenging problems that will improve accelerator performance and understanding of the physics behind. Responsibilities Key Responsibilities • Contributes to solutions of problems and issues ranging from limited scope and basic complexity to projects of moderate complexity, generally in support of more senior scientists. • Solutions use established basic standards, practices and procedures as well as technical knowledge to address problems and complete tasks. • Focus is on applying academic knowledge to the work environment and developing good work/team habits. • Design, execute and analyze DPF experiments. • Develop, commission, and operate DPF diagnostics. • Build, validate, and apply physics models and Multiphysics simulations; compare to experimental data and iterate designs. • Apply targeted Machine Learning to speed up tuning, improve diagnostics insights, and support experiments planning; build data workflows and integrate with controls where appropriate, validate models against measurements. • Author test plans, procedures, and technical reports; present results to program leadership and external partners. • Work safety with high voltage, radiation, vacuum/pressure systems; follow Work Planning & Control and configuration management. • Collaborate across controls (timing/EPICS), solid state pulse power, alignments, targets, and operations. Scientist I (Role Expectations): • Execute well-scoped tasks under mentorship; own sub-system/test; grow into project ownership within 6-12 months. • Contributes to solutions of problems and issues with limited scope and basic complexity. • Defines specifications for procurements and initiates purchase requests. • Follows established technical procedures and instructions. • Assist in compiling and summarizing scientific data. Utilizes technology solutions for both experimental and operational needs. • Assists in data cleaning, baseline models, and simple optimization trials under mentorship. • Consistently practice Work Planning & Control; participate in pre-job briefings, wear required PPE, exercise stop-work authority and promptly report near-misses. Scientist II (Role Expectations): • Own experimental or modeling packages; mentor juniors; contribute to hazard analysis and test readiness reviews. • Assists in researching, compiling and analyzing scientific data. Participates in developing field programs and prepares designs, strategies, reports and proposals. Implements and uses technology solutions for both experimental and operational needs. • Own a focused Machine Learning use case with clear success metrics. • Lead pre-job briefs for small tests; author/update Job Hazard Analysis, verify LOTO/controls, and capture lessons learned after activities. Qualifications Scientist I: ($67,704.00 to $101,566.40) Qualifications • Minimum Education and Experience: Bachelor's degree in a calculus-based (STEM) field. Skill building experience must demonstrate either deeper technical specialization or additional cross-disciplinary knowledge. Graduate research experience may be recognized. Highly Desired • Coursework or project experience in at least one: accelerator physics, HV/pulsed power, vacuum systems, radiation detection, plasma physics, optical diagnostics. • Proficiency in Python for data analysis. • Strong lab skills: ability to follow procedures and write clear test notes. Desired • Hand-on with optical plasma diagnostics and/or vacuum hardware • Safety awareness for HV/radiological work. Scientist II: ($83,075.20 to $124,612.80) Qualifications • Minimum Education and Experience: Bachelor's degree in a calculus-based (STEM) field, plus at least 2 years' relevant experience. Skill building experience must demonstrate either deeper technical specialization or additional cross-disciplinary knowledge. Graduate research experience may be recognized. • Demonstrated ability to design and analyze accelerator experiments and simulation with traceability to requirements. • Experience integrating models with experimental data; author technical reports. Desired • Lead a small test campaign or subsystem from plan through execution to report. • Experience with one or more codes: LSP, CHICAGO, FLAG, COMSOL, MNCP, Geant4. • Basic LabVIEW DAQ; vacuum alignment practices. Additional Information: • The primary work location will be the Losee Road facility in North Las Vegas, Nevada with frequent visits to the Nevada National Security Site (forward areas are approximately 90 miles from North Las Vegas). • Work schedule for this position will be 4/10's, Monday - Thursday (subject to change). • Pre-placement physical examination, which includes a drug screen, is required. MSTS maintains a substance abuse policy that includes random drug testing. • Must possess a valid driver's license. Annual salary range for this position is: Scientist I $67,704.00 - $101,566.40 Scientist II $83,075.20 - $124,612.80 Starting salary is determined based on the position market value, the individual candidate education and experience and internal equity.
