Internship – Venture Development (f/m/x)

About the company

Founded in 2019, Marvel Fusion is Europe’s leading fusion energy company, uniting 120 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.

Your tasks

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

What you will own You will be embedded directly in Corporate Development and work across multiple areas of Marvel Fusion, depending on where the biggest impact is needed at the time you join. We shape the role together based on your background, your interests and our current priorities.

What you will always be working on in some form:

• Owning at least one core project end to end, visible to leadership
• Driving efficiency and process improvements across the company
• Supporting organizational topics and cross-functional initiatives
• Acting as a Swiss Army knife across departments, wherever the need is greatest

Beyond that, your projects will vary. One intern might build financial models and support investor materials and due diligence. Another might go deep on operations or process optimization. That is the point. You will be where Marvel Fusion needs sharp, fast, hungry people the most.
