Thermal-Structural Engineer

Employment Type

: Full-Time

Industry

Brief: Commonwealth Fusion Systems (CFS), an MIT spinout pursuing the fastest, surest way to clean, limitless fusion energy, is looking for an early-career engineer with experience in thermal and structural modeling of heat transfer in solids and testing of components under extreme thermal loads.

CFS’ mission is to enable world-wide clean energy for everyone, creating a sustainable environment for current and future generations. We’ve created a credible path to an operating fusion power plant in 15 years which leverages our novel collaboration with MIT and funding from strategic and financial investors who share our vision. This begins by developing a new class of high-field superconducting magnets that will enable the SPARC tokamak to demonstrate net energy from fusion for the first time. To execute this plan, we are now looking to add talented people to the team who:

  • are mission-driven and treat people well;
  • improve our team by adding diverse perspectives and new ways of solving problems;
  • have demonstrated exceptional results through a range of different pursuits; and
  • have skillsets and experience that relate to the following role:

Thermal-Structural Engineer

The SPARC tokamak will expose its plasma-facing surfaces to heat fluxes greater than any fusion experiment to easily exceeding that in rocket propulsion systems and the surface of the sun. Careful engineer and qualification of high heat flux “armor” will be crucial to the mission of SPARC. The Thermal-Structural Engineer will:

  • work within a multi-disciplinary team of physicists and engineers as part of collaborative sponsored research projects at the MIT Plasma Science and Fusion Center;
  • collaborate with boundary plasma physicists on specifying the thermal and electromagnetic mechanical loads on the plasma-facing surfaces;
  • develop engineering concepts for the plasma-facing components (i.e., divertor, limiter, and first wall);
  • identify and work with material suppliers; and
  • test designs in pulsed, high heat flux facilities.

The ideal candidate will have:

  • at least a master’s degree in a relevant engineering field or equivalent industrial experience;
  • expertise in coupled heat transfer in solids and thermally-induced stress problems (like those in rocket nozzles, thermal protection systems, fusion first walls, arc furnaces, petroleum engineering, etc.);
  • a background in theoretical and computational thermodynamics and mechanics of materials;
  • experience with advanced constitutive modeling to capture irreversible microstructural evolution;
  • generated custom user materials in finite element packages;
  • knowledge of cyclic thermal fatigue issues in refractory metals and/or carbon composites;
  • experience in simulating transient electromagnetics as well as engineering components for use in vacuum;
  • familiarity in applying ASME, ASSTM, and other mechanical standards to design solutions;
  • designed and performed experiments to test engineering models;
  • exceptional attention to detail and safety;
  • an ability to clearly express and critique ideas;
  • an emphasis on elegance and simplicity over complexity;
  • a drive towards commercially viable solutions;
  • a history of thriving in fast-paced, dynamic environments; and
  • values that align with our company’s values of integrity, execution, impact, and self-critique.

If you share our mission and believe you are a good fit for this position, please send a cover letter and resume to jobs@cfs.energy, with “Thermal-Structural Engineer” in the subject line.

At CFS, we deeply value diversity and are an equal opportunity employer by choice.
