About the company:

Commonwealth Fusion Systems (CFS) has the fastest, lowest cost path to commercial fusion energy.

CFS is collaborating with MIT to leverage decades of research combined with new groundbreaking high-temperature superconducting (HTS) magnet technology. HTS magnets will enable compact fusion power plants that can be constructed faster and at lower cost.

The mission is to deploy fusion power plants to meet global decarbonization goals as fast as possible. CFS has assembled a team of leaders in tough tech, fusion science, and manufacturing with a track record of rapid execution. Supported by the world’s leading investors, CFS is uniquely positioned to deliver limitless, clean, fusion power to combat climate change.

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 Scientific Software Engineer

The Scientific Software team at CFS develops software that helps us understand superconducting magnets and tokamaks. The primary project for this role will be development of internal simulation tools for superconducting magnets.

HTS magnets are a key component to CFS’s path to commercial fusion. We seek an experienced software engineer (Senior to Principal level) to help develop computational tools to aid the design, construction, and test of HTS magnets. This includes tools to predict the physical behavior of magnet components (using finite difference, finite element, boundary element methods, etc.), optimize magnet design, perform data analysis and post-processing, visualize data, etc. The software engineer will work directly with software users across interdisciplinary and diverse teams involved in magnet development (electromagnetics, engineering, materials, etc.).

#LI-Remote

At CFS, we excel in fast-paced environments, driven by our values of integrity, execution, impact, and self-critique. As we grow, we’re eager to bring on mission-driven folks who offer diverse perspectives and fresh ways to tackle challenges.

We value diversity deeply and are proud to be an equal opportunity employer by choice. We consider all qualified applicants equally, regardless of race, color, national origin, ancestry, citizenship status, protected veteran status, religion, physical or mental disability, marital status, sex, sexual orientation, gender identity or expression, age, or any other basis protected by law.

What you'll do:

Work as part of a team to develop simulation software across multiple domains of physics and computational approaches

Discover need for, plan implementation of, and deliver software interfaces that meet the needs of multiple internal teams

Help scientists and engineers build application workflows using internal simulation tools

Implement CI/CD processes to reduce maintenance overhead and error rates

What we’re looking for:

Bachelor’s degree in a technical field preferred

Worked on high-consequence software for analysis of physical systems

Programming language: Python, including type hinting

Completed a large project either in a strongly typed language or rigorously using the type hinting features of Python.

Experience in independently setting up a new software project, including CI/CD processes, linting, unit testing, and software documentation

Solid understanding of numerical methods, optimization techniques, linear algebra, and differential equations

Bonus points for:

Programming languages: C++, Rust, or experience with low-level performance and memory management.

Concurrency and parallelization

Simulation and solution strategies for physical systems

Packaging and distribution of software

Proficient in one of the following domains:

o Computational structural mechanics

o Computational electromagnetics

Experience with optimization, machine learning, developing surrogate models, etc

Must-have Requirements:

Perform activities such as typing or sitting for extended periods of time

Dedication to safety to mitigate industrial hazards that may include heat, cold, noise, fumes, strong magnets, lead (Pb), high voltage, and cryogenics

Willingness to travel or work required nights/weekends/on-call occasionally
