## 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
- 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

The impact you will make

As Optomechanical Engineer, you will design and deliver precision optical-mechanical assemblies for high-power laser facilities, with particular emphasis on beam transport and vacuum-compatible systems.

You will take ownership from concept and mechanical analysis through drawings, manufacturing, assembly, alignment, integration and commissioning, working closely with laser, optics, vacuum and controls specialists.

## Your responsibilities

- Design precision optomechanical assemblies including mirror mounts, positioning stages, optical supports and beam transport structures for high-power laser systems.
- Develop vacuum-compatible mechanical designs, selecting suitable materials, seals, feedthroughs and motion mechanisms while considering cleanliness, outgassing and thermal performance.
- Produce 3D CAD models, detailed manufacturing drawings, GD&T, tolerance analyses, bills of materials and controlled engineering documentation.
- Perform or coordinate structural, modal, vibration and thermal analyses to ensure optical alignment, mechanical stability and positioning accuracy.
- Coordinate fabrication and supplier activities; support precision assembly, optical alignment, installation, integration, troubleshooting and commissioning.

## What you bring

- Bachelor's or Master's degree in Mechanical Engineering, Optomechanics, Precision Engineering, Mechatronics or a related field.
- Proven experience designing precision optomechanical devices and mechanisms, ideally for high-power lasers or scientific instrumentation.
- Practical experience with vacuum-compatible mechanical systems and beam transport assemblies, including mechanical interfaces and alignment concepts.
- Strong skills in 3D CAD, manufacturing drawings, GD&T, material selection, precision machining and mechanical tolerance management.
- Hands-on experience with manufacturing follow-up, assembly, alignment, testing and commissioning in multidisciplinary technical environments.

What sets you apart

- Experience with high-energy laser beamlines, large optics, laser compressors or complex scientific facilities.
- Knowledge of high-vacuum or ultra-high-vacuum practices, vacuum cleanliness, motion feedthroughs and pumping-system interfaces.
- Experience with structural and thermal FEA, modal analysis, vibration isolation and stability-sensitive optical systems.
- Familiarity with motorized positioning stages, actuators, encoders and precision alignment methods.
- Independent problem-solving, practical engineering judgment and effective collaboration with optics, laser, vacuum and controls teams.

## What we offer

Our mission is motivation enough for many. But we also support our team with benefits that foster wellbeing and growth:

- Public Transport Subsidy
- Employee Incentive Program
- Phone Bill Reimbursement
- Wellpass or Complimentary Private Health Insurance
- Professional Learning & Development Budget
- Relocation Support
- Company Pension Plan
- 30 Days of Vacation plus additional half day on 24. & 31.Dec.
- Modern Office in the center of Munich
- Healthy office snacks
- Regular Team Events

## 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.
