Job description

Location: Livermore, CA

Title: Physicist (NWS 00956)

THIS POSITION IS SHORT TERM, MAX 1000 HOURS PER CALENDAR YEAR

North Wind Services (NWS) is a high performing, low risk company with a successful history of contributing to their client's missions. NWS executes and manages a wide range of technical services such as environmental investigation and restoration, construction, demolition, radioactive and hazardous waste management, public communication/involvement, information management, health and safety, industrial hygiene, and emergency response/HAZMAT services.

North Wind Services is actively seeking individuals who can contribute to national security within the science, technology, and engineering fields as part of our supplemental labor team at vital federal research and development installations supporting the Department of Energy. Qualified applicants must be a US citizen, at least 18 years of age, and able to meet pre-employment requirements including any required physicals, drug screen, and/or background investigation to satisfy clearance requirements from the Department of Energy.

Successful candidates will be employees of NWS supporting the missions of their federal client, Lawrence Livermore National Laboratory (LLNL) in Livermore, CA. Pay, benefits, Human Resources, and employment management functions are all provided by NWS. As an NWS employee working at LLNL, within the client's environment, you will complete day-to-day tasks, with direction from technical personnel directly employed by LLNL.

The successful candidate will work on-site to run codes, analyze results and attend meetings. The successful candidate will act as a senior level subject matter expert with minimal oversight and close collaboration with LYNM management.

Essential Duties

• Transfer and share knowledge to mentor Design Physics Division personnel.
• Apply expertise to address programmatic questions for the Low Yield Nuclear Monitoring (LYNM) Program and predict the observed responses.
• Simulate magnetic moments produced by chemical explosions and compared the results directly with data from previous experiments.
• Improve the understanding of magnetic and electric field source generation due to coupled and partially decoupled explosions.
• Generate input files for multi-physics calculations for the LYNM program, interpreting their results and aiding in the technology transfer of this expertise to a new code and staff member(s).
• Ensure the new code can replicate the coupled solutions representing flux-bubble phenomena.
• Understand the source generation of EM signals to better classify events remotely.
• Perform additional job duties as assigned.

Essential Skills, Knowledge, and Abilities

• Ph.D. in Physics, Engineering or Applied Sciences with over 10 years of hands on experience in multi-physics calculations.
