Job description:
Your Job:
In this position, you will be an active member of the SDL “Fluids & Solids Engineering” with the following tasks:
- You will work together with international partners in EU-funded projects
- You will invent, implement, and benchmark novel AI tools (reinforcement learning, physics-informed neural networks, graph neural networks, transformers, etc.) for the integration in multi-physics simulation codes
- You will work on analyzing the accuracy and scalability of such methods, and will improve the performance of AI models with Hyperparameter Optimization (HPO) methods
- You will develop code for and run large-scale multi-physics / CFD simulations in the context of biofluid-mechanical applications, and will evaluate and document the results in the form of open-source software, open-access publications, and project reports
- You will join the development of itwinai, a Python library that streamlines AI workflows
- In all of these activities, you will make use of JSC’s cutting-edge HPC- and Quantum-hardware
Your Profile:
- Master`s and preferably subsequent PhD degree in Engineering, Physics, Computer Science or other related fields
- Experience in the development of numerical methods for CFD application, specifically lattice-Boltzmann and finite volume methods
- Experience in programming in Python and C++, and in using scripting languages commonly used on Unix systems. Additional languages or experience with libraries for utilizing GPU hardware efficiently, e.g., CUDA, are a plus.
- Experience in AI programming with, e.g., PyTorch(-DDP), Horovod, or DeepSpeed, and in HPO
- Experience in running large-scale simulations on HPC systems with heterogeneous hardware, using CPUs/GPUs
- A generalist with an interest to solve challenges using a large set of diverse software tools and applications
- Excellent written and spoken English
- Ability and willingness to work in an international, interdisciplinary, and distributed team; willingness to travel (also for short stays at partner institutions) for, e.g., scientific exchange and or intense project hackathons.
Note that it is not necessary to fulfil all of these requirements in order to be considered for the position. We want you to fit in with us as a person, not just your profile.
Our Offer:
We work on the very latest issues that impact our society and are offering you the chance to actively help in shaping the change! We support you in your work with:
- A diverse range of activities in an engaged and experienced team
- Work on frontiers of scientific and technological challenges with access to cutting-edge and unique supercomputing systems including the upcoming first Exascale computer in Europe
- Comprehensive training courses and individual opportunities for personal and professional further development
- Extensive company health management
- Ideal conditions for balancing work and private life, as well as a family-friendly corporate policy
- Flexible work (location) arrangements, e.g. remote work in accordance with the tasks
- Flexible working hours in a full-time position (39 hours/week) with the option of slightly reduced working hours
- 30 days of annual leave and provision for days off between public holidays and weekends (e.g. between Christmas and New Year)
In addition to exciting tasks and a collaborative working atmosphere at Jülich, we have a lot more to offer: go.fzj.de/Benefits
The position is initially for a fixed term of 2 years, with possible long-term prospects. Salary and social benefits will conform to the provisions of the Collective Agreement for the Public Service (TVöD-Bund), pay group 13, depending on the applicant’s qualifications and the precise nature of the tasks assigned to them.
We welcome applications from people with diverse backgrounds, e.g. in terms of age, gender, disability, sexual orientation / identity, and social, ethnic and religious origin. A diverse and inclusive working environment with equal opportunities in which everyone can realize their potential is important to us.
This research center is part of the Helmholtz Association of German Research Centers. With more than 42,000 employees and an annual budget of over € 5 billion, the Helmholtz Association is Germany's largest scientific organisation.
Company
The Helmholtz Association contributes to solving major challenges to assure the future of our society. With more than 39,000 people on staff in 18 national research centres, the Helmholtz Association is Germany’s largest scientific organization. The name Helmholtz stands for concerted research in which networks form the key principle behind inquiring thought and action. Concerted research is efficient and flexible.
The profile of the Helmholtz Association
The Helmholtz Association performs cutting-edge research which contributes substantially to solving the grand challenges of science, society and industry. To succeed in meeting these responsibilities, Helmholtz concentrates its work in six research fields: Energy, Earth and Environment, Health, Key Technologies, Matter, as well as Aeronautics, Space and Transport. Within each of these fields, research programs are developed by our scientists and regularly evaluated by renowned international experts. Their evaluation forms the basis for the programme-oriented funding that is allocated to Helmholtz research. Within the six research fields, Helmholtz scientists cooperate with each other and with external partners – working across disciplinary, organizational and national borders.
Promoting young academics
Helmholtz scientists, a high-performance infrastructure and modern and efficient research management are the ingredients to the Helmholtz Association‘s success and global impact.
Promoting young researchers is a major priority for the Helmholtz Association. Its qualification schemes for young researchers are geared mainly towards PhD students, postdocs and young managers. The Helmholtz Association has set high standards for its talent management. Its strategy begins with targeted recruitment of highly qualified staff at all levels, followed by comprehensive support aimed at further developing their potential. Ensuring equal opportunities is an essential element in all talent management activities undertaken by the Helmholtz Association.
The Helmholtz Graduate Schools and Research Schools at almost all Helmholtz Centres provide doctoral students with the general and specific skills and training they need, as well as ample opportunity to network with other working groups. The period following a doctorate is decisive in determining the direction and success of a scientific career. For this reason, we are about to establish Career Centers for postdoctoral researchers in the Helmholtz centres and a mentoring programme for especially gifted PostDocs in order to foster career orientation. This equips young researchers with the skills they need to go on to head a Helmholtz Young Investigators Group, for example. As a Young Investigator Group leader, junior scientists can independently set up their own group to conduct research in their specialist field.
Within its talent management strategy, the Helmholtz Association pays special attention to the increased recruitment of talented female scientists both from Germany and abroad. To this end, there are currently two funding programs supporting this policy ‘Funding of first-time appointments of excellent women scientists (W2/W3)’ and ‘Funding to recruit top-level international women scientists (W3)’.
The increasing complexity of the content, structures and framework conditions of scientific work today requires researchers to organise their projects, their employees and, of course, themselves in a highly professional and effective way. In response to these demands, we have set up the Helmholtz Management Academy to provide junior leaders in science with professional management training. Furthermore, the Helmholtz network provides a platform for the alumni of the Helmholtz Management Academy and Mentoring programme to come together and share their experiences of leadership, career development and lifelong learning.
