YOUR IMPACT

As a Welding Engineer at Proxima Fusion, you will play a pivotal role in developing and qualifying advanced welding techniques for the Alpha Stellarator -our first integrated fusion prototype. Your work will directly shape the materials and joining processes that enable the extreme precision and performance our fusion hardware demands.

You will be the technical expert in welding processes, metallurgy, and material behavior, helping us build a new class of scientific and industrial machinery from the ground up.

WHAT YOU WILL DO

• Develop, qualify, and implement welding processes for the Alpha project - including electron beam welding, laser welding, narrow-gap TIG, and TIG welding - ensuring quality, repeatability, and compliance with technical specifications.
• Collaborate with design engineers to ensure that weld joints meet structural, thermal, and metallurgical requirements for manufacturability and performance.
• Define welding procedures, parameters, and work instructions; support the qualification of welders and external suppliers .
• Design and execute materials testing campaigns , including destructive and non‑destructive tests, to evaluate weld integrity, mechanical properties, and microstructure.
• Work closely with internal and external teams to evaluate material compatibility, process feasibility , and identify solutions to material‑related challenges.
• Serve as the in‑house expert on welding and materials performance, supporting both coil manufacturing and stellarator assembly workflows.

WHO YOU ARE

• Experience developing and qualifying EB, laser, TIG, and narrow‑gap TIG welding processes in high‑precision applications.
• Strong understanding of welding metallurgy , including heat‑affected zones, microstructure, and residual stresses.
• Familiarity with destructive and non‑destructive testing (e.g. tensile, hardness, NDT) and relevant codes (ASME, ISO, AWS).
• Clear communicator and collaborator across design, manufacturing, and supplier teams.
• Bonus : Exposure to cryogenic, high‑vacuum , or exotic material environments
• Degree in Welding Engineering, Materials Science, Mechanical Engineering, or related field.
• Fluent in English; German a plus.

INTERVIEW PROCESS

• Recruiter Interview (30-60 min)
• Technical Screening (30 min)
• Technical Panel (3x60 min)
• CEO call (30 min)

At Proxima Fusion, our mission is bold : making limitless clean energy a reality. To get there, we need a high‑performing, diverse team that brings different perspectives, challenges assumptions, and builds together with purpose.
