## Description (the employer's text)

### 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
