Computational Physicist - Fluid Modeling of Z Pinch Plasmas

Everett, WA · Science/Research

Zap Energy is currently looking for an experienced Computational Physicist to assist in developing fluid plasma models that will guide understanding of Z pinch operation. Working in collaboration with the Theory & Modeling team, the Physicist will be responsible for developing computational tools and techniques that contribute to efforts to model Z pinch physics, including compression physics, shock heating, turbulent transport, atomic and molecular reactions, etc. The high-level objective of the modeling is to provide a predictive understanding of the physical processes that determine plasma density and temperature, and to build predictive understanding that will guide experimental design and operation. The ideal candidate is an organized, inventive problem solver, and an effective team player with proven technical ability. 
Responsibilities and Duties: 

  • Develop and implement modeling that captures the essential physics in the formation and compression dynamics of the Z-pinch plasma 

  • Attend conferences and produce publications describing research results 

  • Reports to the Zap Energy Theory & Modeling Lead 

Qualifications and Skills: 


  • MS in plasma physics, fluid dynamics, turbulence, combustion or closely related field 

  • Detailed knowledge of scientific computing, including direct experience with CFD or MHD algorithms 

  • Excellent coding skills, including C++, Fortran, MPI, etc. 

  • Excellent written and communication skills 

  • Demonstrated publication record 


  • PhD with 3 - 10 years post-PhD experience 

  • Experience in an industry setting using modeling to support product development 

  • Experience with sub-grid modeling of turbulent transport 

  • Experience with atomic and molecular physics of plasmas or related combustion reaction chemistry 

  • Expertise in high-performance computing workflows 

  • Familiarity with software-development practices including the Git version-control system 

Benefits of joining Zap Energy - While doing meaningful work is rewarding in itself, we also offer the following programs and benefits for all employees: 

  • Competitive salary and benefits 

  • Premium medical / dental / vision insurance 

  • Flexible vacation and paid company holidays 

Zap Energy is building a low-cost, compact and scalable fusion energy platform that confines and compresses plasma without the need for expensive and complex magnetic coils. Zap’s sheared-flow-stabilized Z-pinch technology offers the shortest potential path to commercially viable fusion and requires orders of magnitude less capital than traditional approaches. Zap Energy has over 60 employees in two facilities near Seattle and is backed by leading financial and strategic investors.   Zap Energy is an equal opportunity employer.  All qualified applicants will receive consideration for employment without regard to age, ancestry, color, family or medical care leave, gender identity or expression, genetic information, marital status, medical condition, national origin, physical or mental disability, political affiliation, protected veteran status, race, religion, sex (including pregnancy), sexual orientation, or any other characteristic protected by applicable laws and regulations.
