Welding Engineer

Posted January 01, 2021
Apply: Commonwealth Fusion Systems


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 & new ways of solving problems; have demonstrated exceptional results through a range of different pursuits; and have skillsets and experience that relate to this role.

High-temperature superconductors (HTS) have reached commercial maturity and present an opportunity to change the way superconducting magnets are built and used. These magnets are the key technology for building a fusion power plant that will revolutionize clean energy production for the world. The welding engineer will lead in-house weld development to grow the production line from development to full-scale production.

This team member will:
    • Develop welding and non-destructive test processes and certification plans in compliance with appropriate standards and codes
    • Develop and qualify Welding Procedure Specifications (WPS) and Procedure Qualification Records (PQR)
    • Evaluate and create weld processes for both manual and automated welding
    • Provide manufacturability feedback to design engineers for weld geometries and material selection
    • Select and commission welding equipment needed to support production and create maintenance plans
    • Work with in-house welders and external vendors to weld and inspect large metallic structures and tooling within specified timelines and budgets
    • Troubleshoot and resolve manufacturing discrepancies with a focus on continuous improvement
    • Influence make vs. buy decisions and work with external vendors to augment internal capabilities


The ideal candidate will have most, if not all, of these requirements:
    • Bachelor's degree in engineering field is required, weld engineering preferred
    • 10+ years' experience as a welding engineer on large structural systems and tooling
    • Experience with large metallic structures and manufacturing processes related to machining, welding, drilling, and non-destructive test methods
    • Experience taking products from R&D into production, including developing welding techniques to transition from manual to automated processes
    • Project management experience working with internal customers and external vendors to deliver manufactured hardware within specified timelines and budgets
    • High self-motivation and drive to execute quickly with excellent troubleshooting/problem-solving skills
    • Proficiency in CAD for tooling design is preferred (NX & Teamcenter is a plus)


CFS team members thrive in a fast-paced, dynamic environment and have demonstrated exceptional results through a range of different pursuits. We all tightly align with our company values of integrity, execution, impact and self-critique. As we grow, we are looking to add talented people who are mission driven and bring diverse perspectives and new ways of solving problems.

At CFS, we deeply value diversity and are an equal opportunity employer by choice. We consider all qualified applicants equally for employment. We do not discriminate on the basis 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, ordinance, or regulation.
