The Jülich Supercomputing Centre (JSC) operates supercomputers of the highest performance class, enabling scientists and engineers in Germany and Europe to tackle some of the most complex and challenging problems of our time. Whether unlocking the secrets of fundamental particle physics or cosmology, designing advanced nanomaterials, exploring laser-based x-ray microscopes, or accelerating the development of sustainable energy technologies, a key element of these endeavours is the ability to model their underlying physical processes in finer detail and at realistic scales. Within the framework of the pan-European infrastructure project PRACE (“Partnership for Advanced Computing in Europe”), JSC has acquired funding with the 6IP Programme “Forward Looking Software Solutions” to develop community codes capable of running efficiently on advanced supercomputer architectures.

To pursue this new initiative, we are seeking as soon as possible a

Computational Research Scientist

Your Job:

  • Redesigning and tuning the popular EPOCH particle-in-cell code in order to fully exploit contemporary and future supercomputing architectures. This will involve a wide range of activities, from basic performance analysis, to conceptual design and implementation of key algorithmic components.
  • Facilitating the exascale readiness of kinetic plasma physics applications in cooperation with leading developer teams, thereby enabling groups from this community to tackle new ‘real-world’ simulation challenges
  • Participation in collaborative projects involving the Plasma Physics Simulation Laboratory at JSC. This is an established team with a unique research and support mandate – actively linking the laser-plasma and fusion communities to the rapidly evolving high-performance computing landscape
  • Close cooperation and interaction with leading EU plasma physics institutes such as ELI and ITER


Your Profile:

  • University degree in applied mathematics, computer science, physics or computational sciences
  • Experience or specialisation in kinetic plasma modelling, ideally particle-in-cell codes would be advantageous
  • Good programming skills with high-level languages (for example FORTRAN and/or C/C++) and ideally also Python
  • High performance parallel computing with MPI, OpenMP or pthreads
  • Experience with modern performance analysis tools is an advantage
  • Ability to work independently as well as collaboratively in an international, interdisciplinary working environment
  • Very good communication and organisational skills
  • Fluent in spoken and written English; good written and spoken German an advantage



Our Offer:

  • Development of your personal strengths through a wide spectrum of advanced training and professional development programs
  • Exciting working environment on an attractive research campus with excellent infrastructure, located between the cities of Cologne, Düsseldorf, and Aachen
  • International and interdisciplinary working atmosphere
  • A comprehensive further training programme
  • Flexible working hours and various opportunities to reconcile work and private life
  • Limited for 2 years with possible longer-term prospects
  • Full-time position with the option of slightly reduced working hours
  • Salary and social benefits in conformity with the provisions of the Collective Agreement for the Civil Service (TVöD)


Forschungszentrum Jülich aims to employ more women in this area and therefore particularly welcomes applications from women.

We also welcome applications from disabled persons.
