  • Harness the latest breakthroughs in numerical optimization, artificial intelligence, and computational hardware to enhance the predictive capabilities of simulations and identify optimal configurations for stellarator operation.
  • Identify key parameters and constraints for optimization and respond in an agile and proactive way to changes in design requirements.
  • Harmonize the designs with requirements from other departments.
  • Take part in establishing a comprehensive solver for coupled equilibria involving plasma, liquid walls, coil winding surface and coils.
  • Participate and assist the definition and realization of intermediate milestones, by designing prototypes, establishing experimental procedures and processing measurement data by means of customized computational tools and analysis.
  • Validate mathematical models through comparison with experimental data and contribute to the continuous improvement of computational tools for stellarator design and operation.
  • Contribute to the development of new methodologies and means to push the boundaries of stellarator performance.

• Scientific outcome
  • Prepare scientific reports, presentations, posters, etc., and represent Renaissance Fusion to scientific conferences, workshops, dedicated panels and/or the general public.
  • Proactively propose and/or contribute to the writing of patent filings and scientific papers.
  • Put forward proposals for collaborations and grants.
  • Remain on the forefront of scientific developments in his/her field of expertise.

Requirements

Do not hesitate to apply if you don’t meet all the requirements. Superheroes don’t exist, but people with talent and passion do!
