Laser Scientist

Founded in 2019, Marvel Fusion is Europe’s leading fusion energy company, uniting 75 scientists, engineers, and entrepreneurs across our locations in Munich and Colorado.

Backed by over €385 million in public and private funding, we’re driven by a shared mission: to deliver clean, abundant energy to the world.

By joining us, you will be:

• Solving one of the most complex technological challenges known to humanity, harnessing Fusion on Earth
• Part of a highly purpose-driven team working on providing the world with clean, safe and abundant energy
• Working alongside world-leading scientists and entrepreneurs in the field of Fusion
• Part of a start-up where growth on a company and individual level is the default

As a Laser Scientist at our new Fort Collins, CO facility, you will play a critical hands-on role inestablishingthe laboratory infrastructure,deploying Marvel Fusion’s ultra-high-intensity laser systems, and designingnext-generation lasers and experiments.

Beyond laser installation andlaboratorycommissioning, you will help set up laboratory spaces, equipment, workflows, and safety processes—turning an empty facility into a fully operational laser lab. You will also regularly travel to other Marvel Fusion and partner sites, primarily within the US and occasionally worldwide, to support system integration, commissioning, and experimental campaigns. You will also play a hands‑on role in developing new laser and optical technologies to support thedevelopmentoflaser‑driven inertial fusion.

This role is ideal forscientistswho enjoy building things from scratch,developingcutting‑edge technology,working on‑site, travelingfrequently, and taking ownership of real‑world technical challenges.
