## Job description

## Who we are

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.

## Why Marvel Fusion

By joining us, you will be:

- Solving one of the most complex technological challenges known to humanity, harnessing Fusion on Earth

- 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.

## About Marvel Fusion

## Core Business
- **Primary industry**: Electric Power Generation / Fusion Energy
- **Target customers**: B2B – utilities, grid operators, and industrial energy consumers
- **Mission**: “Enable humankind to access clean, safe & reliable energy by developing a laser-driven fusion power plant”

## Products & Services
- **Laser-Driven Fusion Power Plant**: An advanced inertial fusion energy concept combining a proprietary fast ignitor with innovations in laser technology, target design, and energy extraction. The approach builds on the validated physics demonstrated at the National Ignition Facility in 2022 and aims to eliminate the need for tritium through alternative fuel cycles.

## Market Standing
- **Valuation/Market Cap**: Not disclosed
- **Key Metric**: Total funding exceeds **USD 400 million** (public + private) per the company website; LinkedIn reports **USD 187.2 million** in tracked funding rounds – the difference likely reflects additional public grants and undisclosed investments.
- **Notable Investors/Partners**: EQT Ventures, Siemens Energy, European Innovation Council (EIC) Fund, Tengelmann Ventures, and a network of leading industrial suppliers.
- **Growth Signals**:
  - Headcount of **81 employees** (42.9% YoY growth)
  - Inauguration of new experimental chamber “LION 2” at CALA in Garching, Munich (July 2025)
  - Awarded U.S. DOE grant to advance laser fusion (September 2025)
  - Public-private partnership with Colorado State University and infrastructure program in Fort Collins, Colorado
  - Selected for EIC STEP Scale Up Program with potential investment up to EUR 30 million

## Competitive Advantages
- **Validated physics**: Approach is based on the fusion ignition gain demonstrated at the National Ignition Facility (2022), reducing technical risk.
- **Proprietary fast ignitor concept** that could lower costs and increase efficiency compared to other inertial fusion designs.
- **Alternative fuel cycles**: Potential to operate without tritium, simplifying fuel supply and waste management.
- **Strong industrial partnerships**: Strategic collaboration with Siemens Energy and deep ties to European and U.S. supply chains.

## Strategic Focus
- Scaling laser-driven fusion toward commercial deployment by advancing laser optics (FusioTile project), target manufacturing, and power plant engineering.
- Expanding U.S. operations: appointment of Puja Gupta as EVP to lead U.S. activities and a major infrastructure hub in Fort Collins, Colorado.
- Securing additional public and private funding to bridge from demonstration to pilot plant.

## Why Work Here
- **Culture**: Values include ownership, empowerment, clarity & trust, diversity of thought, and collaboration. Decisions happen close to the work, and transparency is emphasized.
- **Work model**: Hybrid – offices in Munich (Germany) and Fort Collins, Colorado (U.S.). Some roles may be on-site due to lab and experimental work.
- **Engineering focus**: Opportunities across experimental physics, laser science, controls, IT infrastructure, and data engineering. Active job postings: 11 (as of mid-2026).
- **Perks**: Not publicly detailed, but the company emphasizes impact – working on a breakthrough energy technology with a mission-driven team.
- **Employee sentiment**: LinkedIn rating 3.0/5.0 (7 reviews) with lower scores in compensation (2.3) and career (2.1), but higher in work-life balance (3.4). Small sample size.
