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.

About the Job

We are looking for a highly capable Mechanical/ Optomechanical Engineer to join our team and take the lead in designing and optimizing large, ultra-stable optical mounts for high-energy, ultra-short-pulse laser systems. This role requires expertise in mechanical design, vibration and thermal analysis and precision kinematics. You will collaborate closely with optical physicists and systems engineers to ensure the structural stability and adjustability of critical laser components under demanding operating conditions.

Role & Responsibilities

  • ● Design and optimize large optical mounts capable of maintaining micron/sub micron positioning and high angular stability under thermal loads, mechanical vibrations and environmental changes
  • ● Perform and interpret modal, harmonic, and random-vibration/PSD analyses to identify structural resonances and predict optical displacement and angular stability under realistic environmental excitation
  • ● Translate thermal results into optomechanical performance, evaluating how temperature changes and gradients influence mirror displacement, tip/tilt, surface deformation, optical alignment, and wavefront quality
  • ● Optimize structures for high eigenfrequencies and low vibration sensitivity while maintaining appropriate mass, manufacturability, accessibility, and adjustment capability
  • ● Select appropriate materials based not only on mechanical strength but also on CTE, thermal conductivity, stiffness-to-mass ratio, dimensional stability, vacuum compatibility, and optical-system requirements
  • ● Select and integrate precision adjustment components including thin-film coatings, optical contacting, and precision mechanics

Benefits

  • ● 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
