Our mission is to accelerate the world's transition to fusion energy while safeguarding humankind. This is not a normal company. This is not a normal job. We are committed for the long term to win. ### **About the Role** As a Computational Physicist at Fuse, you'll develop the models and simulations that explore how our pulsed-power systems actually behave — turning physics, mathematics, and computational methods into predictions the team can build on. ### **Core Responsibilities** - Develop and run simulations for pulsed-power systems using MHD, PIC, and circuit models. - Utilize and modify Screamer circuit code for modeling high-voltage pulse generation and delivery. - Conduct magnetohydrodynamic (MHD) simulations to study plasma dynamics in fusion and Z-pinch configurations. - Implement and analyze particle-in-cell (PIC) simulations for plasma interactions and beam dynamics. - Model impedance matching in Marx generators and analyze energy coupling in plasma loads. - Collaborate with experimentalists to validate models and optimize system performance. - Develop custom computational tools and optimize existing codes for high-performance computing (HPC). - Analyze and interpret large data sets, extracting meaningful insights and presenting findings in clear, concise reports. - Develop software tools and algorithms to optimize simulation processes and improve computational efficiency. - Stay up to date with advancements in computational techniques, programming languages, and physical theories to apply state-of-the-art methodologies to projects. - Contribute to academic papers, technical reports, and presentations, sharing results with both internal teams and external collaborators. - Provide technical mentorship and guidance to junior team members. ### **Minimum Qualifications** - Ph.D. or M.S. in Physics, Electrical Engineering, Applied Mathematics, or a related field. - Strong background in computational plasma physics and high-energy-density physics. - Experience with Screamer, MAGIC, HYDRA, or similar circuit and plasma codes. - Proficiency in MHD and PIC simulation techniques. - Strong programming skills in Python, Fortran, C++, or MATLAB for numerical modeling. - Experience with HPC environments and parallel computing. - Strong foundation in theoretical physics, including electromagnetism, classical mechanics, statistical mechanics, or related areas. - Strong problem-solving abilities, analytical skills, and attention to detail. - Ability to present complex results to technical and non-technical audiences. ### **Preferred Qualifications** - Familiarity with Z-pinch, MagLIF, dense plasma focus devices, and fusion energy concepts. - Experience in finite element analysis (FEA) or finite difference time domain (FDTD) methods. - Knowledge of electromagnetic wave propagation and plasma-material interactions. - Experience working in experimental plasma physics or fusion research. - Strong publication record in computational physics or related fields. - Background in developing custom software tools for physical simulations. - Familiarity with version control tools and collaborative software-development practices. - Prior experience publishing research or contributing to academic journals and conferences. ### **What We Value** - Give a shit. Build things you're proud of. - Take responsibility. If something is broken and you can fix it, fix it. See things through. - Move fast. Make decisions, learn quickly, and keep moving forward. - Think bigger. Simplify relentlessly. Don't default to the safe answer. - Disagree and commit. The best idea wins. Once a decision is made, we move. - Desire to win. This is hard. Expect intensity. We are here to win. - Plan B is to make Plan A work. ### **Additional Requirements** This is not a remote position and will require relocation if not already local to the applicable Fuse facility. ### **Benefits** - Medical, dental, and vision coverage. - Relocation assistance for roles that require it. - Flexible time off. Take what you need, no accrual tracking. - 2 weeks of paid time off built into the end of each year, subject to team and business needs. - Supportive leave of absence policies. - Paid leave for new parents. ### **ITAR Requirements** To conform to U.S. Government technology export regulations, including the International Traffic in Arms Regulations (ITAR), you must be a U.S. citizen, lawful permanent resident of the U.S., protected individual as defined by 8 U.S.C. 1324b(a)(3), or eligible to obtain the required authorizations from the U.S. Department of State. ### **Equal Opportunity** Fuse is an Equal Opportunity Employer; employment with Fuse is governed on the basis of merit, competence, and qualifications and will not be influenced by race, color, religion, gender, national origin/ethnicity, veteran status, disability status, age, ancestry, immigration status, sexual orientation, gender identity, marital status, mental or physical disability, or any other legally protected status.
