About Commonwealth Fusion Systems:

Commonwealth Fusion Systems is on a mission to deliver the urgent transition to fusion energy.

Combining decades of research, top talent and new technologies, we’re designing and building commercially viable fusion power plants. And working with policymakers and suppliers to build the energy industry of the future.

We’re in the best position to make it happen. Since 2018, we’ve raised over $2 billion in capital – more than any other fusion energy company in the U.S.

Now we’re looking for more thinkers, doers, builders, and makers to join us. People who’ll bring new perspectives, solve tough problems, and thrive as part of a team.

If that’s you and this role fits, we want to hear from you.

Join the power movement as a Senior Process Engineer

We are seeking an experienced process engineer with strong data analysis skills to join our team. This CFS Senior Process Engineer will be responsible for supporting the installation and the process qualification of new equipment and will oversee continuous improvement activities. This role involves working with advanced vacuum systems, thermal processes, wet processes, and transforming complex datasets into actionable insights. You will work closely with cross-functional teams to drive process improvements through thoughtful, well-communicated analysis.

This role requires compliance with U.S. laws concerning the export of controlled or protected technologies or information (collectively, “Export Control Laws"). Any offer of employment will be contingent on the need for compliance with such Export Control Laws.

Own the process development and qualifications of key process equipment

Develop and conduct design of experiments for process development and characterization

Proactively analyze data to answer key questions and drive process efficiency, and engineering improvements

Develop and maintain data collection processes that support engineering and production workflows

Trace and document data requirements, sources, and flows; contribute to the development of data models

Apply Lean Six Sigma or similar methodologies to improve production processes and reduce variability

Use statistical methods to analyze complex datasets, identify patterns, and support data-driven experimentation and decision making

What we’re looking for:

At least a bachelor’s degree in a relevant engineering field (e.g., physics, chemistry, materials science)

5 to 10 years of relevant experience

The ability to conceive novel solutions to challenging problems

An exceptional safety record and attention to detail

Familiarity with engineering systems in challenging environments

Experience with statistical methods (e.g., control charts, capability analysis, regression, hypothesis testing)

Experience using statistical software such as JMP, Minitab, or similar tools

Strong collaboration and communication skills, with the ability to translate technical findings into actionable recommendations

Bonus points for:

Knowledge of in situ and ex situ metrology tools and methodologies

Knowledge of thin-film characterization tools and methodologies

Proficiency in SQL and Python for data manipulation and analysis
