About the Job

Requirements

  • Scientist I requires a bachelor's degree in a calculus-based STEM field and skill-building experience demonstrating deeper technical specialization or additional cross-disciplinary knowledge; graduate research experience may be recognized.
  • Scientist II requires a bachelor's degree in a calculus-based STEM field, at least 2 years of relevant experience, and skill-building experience demonstrating deeper technical specialization or additional cross-disciplinary knowledge; graduate research experience may be recognized.
  • Scientist II requires demonstrated ability to design and analyze accelerator experiments and simulations with traceability to requirements.
  • Scientist II requires experience integrating models with experimental data and authoring technical reports.
  • A valid driver's license is required.
  • Applicants must be able to obtain and maintain a DOE Q-level security clearance, which requires U.S. citizenship and being at least 18 years of age.
  • Applicants must complete pre-placement physical examination, including a drug screen, and background checks; selected applicants are subject to a federal background investigation and subsequent reinvestigations, and may be required to complete a counterintelligence evaluation, including a polygraph examination.

Responsibilities

  • Contribute to solutions for problems and issues ranging from limited scope and basic complexity to projects of moderate complexity, generally supporting more senior scientists, using established standards, practices, procedures, and technical knowledge.
  • Design, execute, and analyze dense plasma focus experiments.
  • Develop, commission, and operate dense plasma focus diagnostics.
  • Build, validate, and apply physics models and multiphysics simulations; compare them with experimental data and iterate designs.
  • Apply targeted machine learning to speed up tuning, improve diagnostic insights, and support experiment planning; build data workflows, integrate them with controls where appropriate, and validate models against measurements.
  • Author test plans, procedures, and technical reports; present results to program leadership and external partners.
  • Work safely with high voltage, radiation, and vacuum/pressure systems; follow Work Planning & Control and configuration management.
  • Collaborate across controls, including timing and EPICS, solid-state pulsed power, alignments, targets, and operations.
  • For Scientist I, execute well-scoped tasks under mentorship, own a subsystem or test, and grow into project ownership within 6–12 months.
  • For Scientist I, define procurement specifications and initiate purchase requests; follow established technical procedures and instructions; assist in compiling and summarizing scientific data; use technology solutions for experimental and operational needs; and assist with data cleaning, baseline models, and simple optimization trials under mentorship.
  • For Scientist I, practice Work Planning & Control, participate in pre-job briefings, wear required personal protective equipment, exercise stop-work authority, and promptly report near misses.
  • For Scientist II, own experimental or modeling packages, mentor junior staff, and contribute to hazard analysis and test readiness reviews.
  • For Scientist II, research, compile, and analyze scientific data; participate in developing field programs; prepare designs, strategies, reports, and proposals; and implement and use technology solutions for experimental and operational needs.
  • For Scientist II, own a focused machine-learning use case with clear success metrics.
  • For Scientist II, lead pre-job briefs for small tests; author or update Job Hazard Analyses; verify lockout/tagout and controls; and capture lessons learned after activities.

Desired Qualifications

  • Coursework or project experience in accelerator physics, high-voltage or pulsed power, vacuum systems, radiation detection, plasma physics, or optical diagnostics.
  • Proficiency in Python for data analysis.
  • Laboratory skills, including following procedures and writing clear test notes.
  • Hands-on experience with optical plasma diagnostics and/or vacuum hardware.
  • Safety awareness for high-voltage and radiological work.
  • Experience leading a small test campaign or subsystem from planning through execution and reporting.
  • Experience with one or more of LSP, CHICAGO, FLAG, COMSOL, MNCP, or Geant4 codes.
  • Basic LabVIEW data acquisition and vacuum alignment practices.

About the Company

Nevada National Security Site

Manages nuclear deterrent stewardship and emergencies

The Nevada National Security Site supports national security by maintaining the U.S. nuclear deterrent, providing nuclear and radiological emergency response capabilities and training, and advancing nonproliferation efforts, while also preserving the environment of its Cold War legacy. It uses specialized facilities, labs, simulations, and controlled experiments to develop and demonstrate detection, response, and stewardship capabilities in collaboration with national laboratories and federal agencies. Its approach combines government-led missions with hands-on testing, emergency training, and environmental stewardship, setting it apart through its integrated, federally overseen program. The goal is to strengthen national security by keeping a safe deterrent, improving emergency response and nonproliferation work, supporting national-lab experiments, and protecting the environment for future generations.
