Integration Engineer

Who we are

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

In this role, you will shape how complex, facility-scale technical systems come together and perform within high-power laser facilities for laser-driven fusion. You will ensure that high-power laser systems and their supporting technologies (vacuum systems, large optics, precision mechanics, and facility infrastructure) are coherently defined, compatible, and ready for operation. 

Your work will directly influence system performance, facility reliability, and technical risk. By defining requirements, managing interfaces, guiding technical decisions, and leading structured design and integration activities, you will enable complex laser-driven fusion systems to progress smoothly from concept through commissioning. Your contributions will help ensure that the facility meets its technical objectives and operates as intended.

Your responsibilities

• Define and manage system and subsystem requirements for laser-driven fusion facility integration 


• Establish and maintain interfaces between lasers, vacuum systems, optics, mechanics, and facility infrastructure 


• Develop and manage system performance budgets 


• Plan, prepare, and participate in formal design reviews (e.g. PCR, CDR) 


• Ensure traceability between requirements, design, verification, and acceptance 


• Identify, assess, and mitigate technical risks across the project lifecycle 


• Coordinate integration activities across multiple engineering disciplines 


• Produce and maintain integration plans, interface control documents (ICDs), and technical documentation 

This role is primarily based in Munich, with occasional travel to research facilities worldwide.

What you bring

• Bachelor’s or master’s degree in engineering (Optical, Mechanical, Electrical, or related field) 


• More than 5 years of experience integrating complex technical systems in large-scale facilities 


• Experience participating in PCR, CDR, or equivalent structured design reviews 


• Solid understanding of vacuum systems, large optics, and precision mechanics 


• Strong system-level thinking and structured problem-solving skills 


• Strong interpersonal and technical communication skills, with the ability to proactively engage and communicate with diverse stakeholders 


• Excellent writing and oral communication skills in English 

What sets you apart

• Background in high-power laser systems, ideally in a fusion or high-energy-density physics context 


• Experience with defining and integrating facility-wide safety and interlock systems (e.g. radiation safety)
