- Operators of accelerator-based facilities
You will work in an English-speaking, international environment with direct exposure to global projects.
What We Offer
- Competitive salary
- A small, highly specialized international team
- Flexible working conditions with up to 70% remote work (home office)
- Opportunity to take technical ownership of projects and solutions
- Work on highly specialized, real-world applications in a global niche field
The Candidate
You have a background in radiation physics, medical physics, or health physics and apply Monte Carlo methods confidently in practical engineering contexts.
Required
- Strong, hands-on experience with MCNP6, particularly in radiation shielding applications
- Solid understanding of Monte Carlo methods for radiation transport
- Programming skills in Python (C++ or other languages are a plus)
- Ability to work independently and take responsibility for technical work packages
- Ability to communicate effectively with international clients
- Fluency in technical English (German is not required)
Advantages
