@ Commonwealth Fusion Systems

About Commonwealth Fusion Systems

Commonwealth Fusion Systems is on a mission to deliver the urgent transition to fusion energy by designing and building commercially viable fusion power plants. Since 2018, they have raised nearly $3 billion in capital and are the largest private fusion company in the world.

Join the Power Movement as a Computational Materials Scientist

The Materials and Processing Department supports design engineers, supply chain, and manufacturing with materials selection, process validation, and R&D to develop new materials and processes for fusion power deployment. The role contributes to projects like SPARC, the net energy tokamak under construction in Devens, MA, and the ARC fusion power plant.

What You'll Do

• Develop computational toolsets to predict material properties under extreme conditions.
• Collaborate with engineers to establish material design curves and sensitivity parameters.
• Identify knowledge and experimental gaps for simulation model improvements.
• Benchmark and create metrics for variability in manufacturing processes.
• Support writing material standard specifications and manage data workflows.

What We’re Looking For

The ideal candidate has an MS in Materials Science, Applied Physics, Physical Chemistry or a related field with 3+ years of related experience. Experience includes computational materials simulation, coding for material property analysis, predictive model building, and validation with experimental data. A strong understanding of process-structure-properties relationships and materials simulation methods (Atomistic, molecular dynamics, DFT, Monte Carlo, phase field, crystal plasticity, dislocation dynamics, computational thermodynamics) is essential.

Bonus Points

• Experience with ICME tools and multi-scale simulations.
• Ability to simplify complex quantitative data and present findings.
• Effective communication in fast-paced engineering environments.
• Proven track record of taking under-defined problems to completion.

Must-have Requirements

• Ability to perform extended periods of typing or sitting.
• Willingness to work in facilities with industrial hazards including cryogenics and high voltage systems.
• Willingness to travel or work nights/weekends/on-call as required.

Benefits

• Competitive compensation with equity.
• 12.5 company-wide holidays, flexible vacation days, and sick days.
• Generous parental leave, health, dental, and vision insurance.
• 401(k) with employer matching, professional growth opportunities, and team-building activities.
