Job description

The planet urgently needs safe, reliable, zero-carbon energy without waste. Nuclear fusion can address the scale of this problem, but for decades, existing fusion approaches have not proven a net positive energy gain. Zap Energy has rethought the fundamental technology of fusion. As the only company using sheared-flow-stabilized Z-pinch, we present potentially the fastest path to commercially available fusion energy.

As a Research Scientist (Theory), you’ll play a critical role in advancing our understanding of Z-pinch operation. Working closely with our Theory & Modeling team, you’ll develop fluid and kinetic plasma models that guide experimental design and operation. Your work will help predict key plasma behaviors—like density and temperature—and inform strategies for sustaining stable fusion conditions.

Responsibilities:

• Develop and implement models that capture essential physics in the formation and sustainment of the sheared-flow-stabilized Z-pinch
• Build computational tools and techniques for simulating pulsed power flow, compression physics, shock heating, turbulent transport, plasma sheaths, atomic and molecular reactions, two-fluid effects, and 3D phenomena
• Validate models against experimental data and refine predictive capabilities
• Collaborate with experimental teams to integrate modeling insights into device design and operation
• Share findings through publications and presentations at conferences

Qualifications

Required:

• Master’s degree in plasma physics, fluid dynamics, turbulence, combustion, or a closely related field
• Strong knowledge of scientific computing and algorithms (CFD, MHD, continuum kinetic modeling, PIC, etc.)
• Proven ability to communicate complex ideas clearly and effectively
• Demonstrated publication record

Preferred:

• Ph.D. in plasma physics, fluid dynamics, turbulence, combustion, or related field
• Experience validating computational models to experiment
• Familiarity with kinetic plasma physics and modeling
• Background in pulsed power circuits and design
• Knowledge of atomic and molecular physics of plasmas or combustion reaction chemistry
• Experience in industry using modeling to support product development
• Expertise in sub-grid modeling of turbulent transport and high-performance computing workflows

Estimated salary range: $100,000-150,000 annual.

Zap Energy also offers the following:

• Competitive compensation
• Matching retirement contributions
• 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.

Candidates may be considered for other positions at Zap Energy and actual salary will be based on relevant education, experience, and other qualifications. Range is published in accordance with Washington Equal Pay and Opportunity Act.
