Postdoctoral Researcher in High-Performance Computing

Description:

Responsibilities Are you a highly motivated researcher with a burning interest in HPC (high-performance computing) and a drive to solve complex scientific challenges? Do you thrive in an R&D environment where your ideas and the software you develop have a direct impact on cutting-edge research? We are seeking postdoctoral researchers as HPC software researchers at the Scientific Software Unit at KTH Center for Scientific Computing (KCSC). The position is funded by SSF within the SEESSI initiative, which aims to adapt Sweden's leading software in molecular dynamics, computational fluid mechanics, and quantum chemistry for next-generation hardware. You will be part of a project team of HPC software researchers at KCSC that collaborates closely with and creates tangible impact for three of Sweden's leading HPC codes: GROMACS (one of the world's most widely used software packages for molecular dynamics), Neko (a highly scalable framework for computational fluid mechanics that was nominated for the ACM Gordon Bell Prize in 2023), and VeloxChem (a versatile open-source software for quantum chemical calculations). As a postdoctoral researcher, your focus will be on developing innovative, technology-aware algorithmic methods directed toward these strategic software projects. Our goal is to go beyond traditional performance optimization; through an interdisciplinary approach, we further develop or redesign core algorithms for modern HPC architectures, with energy efficiency as a central design criterion. Key research objectives include: Mixed-precision algorithms: Design and implement formulations for core domain-specific computational kernels to leverage low-precision hardware without compromising simulation accuracy. Data-centric optimization: Design and implement communication schemes and data access strategies tailored for systems beyond exascale, for example via GPU-centric communication techniques. Collaboration and impact: We encourage you to publish your research and participate in leading international conferences. This gives you the opportunity to contribute directly to the core codebases and reach a global user community. Qualifications Requirements Completed doctoral degree or foreign degree assessed as equivalent to a doctoral degree. This qualification requirement must be met by the time the employment decision is made. Very good practical experience with software development in modern C++ and/or Fortran. Experience with parallel programming for multi-core processors (CPUs), GPUs, and distributed systems using programming models such as OpenMP, CUDA, SYCL, MPI, and OpenSHMEM. Practical experience optimizing software for large-scale HPC systems, including advanced tracing and performance profiling on modern HPC platforms. Excellent communication skills in English and documented ability to communicate research results as required in daily work. Ability to independently work with technical solutions and research questions while contributing constructively as part of a team. We are seeking a candidate with solid experience in software development for scientific applications and high-performance computing, as well as deep expertise in performance optimization. Merits At the time of the application deadline, no more than three years since the doctoral degree or a foreign degree assessed as equivalent to a doctoral degree was awarded. Experience with performance modeling, performance analysis, and optimization for heterogeneous architectures. Experience with software development in any of the following areas: molecular dynamics, computational fluid mechanics, or quantum chemistry. Experience working with large-scale scientific software projects and research collaborations. Awareness of diversity and equal opportunity issues, with particular emphasis on gender equality. We will place great emphasis on personal qualities. Become Part of KTH KTH shapes the future through education, research, and innovation. As a leading international technical university, we play an active role in driving and contributing to the transition to a sustainable society. Here you have the opportunity to grow and develop at a creative and dynamic workplace with good working conditions and benefits. Gender equality, diversity, and equal opportunities are a quality issue and a natural part of KTH's values as a university and state agency.

Application You apply via KTH's recruitment system. As an applicant, you have primary responsibility for ensuring that your application is complete when submitted. Your application should contain: CV including relevant professional experience and knowledge. Copy of diploma and transcripts from your previous university studies. Translations into English or Swedish if the original documents are not issued in one of these languages. A brief statement of why you wish to conduct research, your academic interests, and how they relate to your previous studies and future goals. Maximum 2 pages. Your application must be received by KTH no later than the application deadline at midnight, CET/CEST (Central European Time/Central European Summer Time). About the Employment The employment is permanent, but for a maximum of two years. A postdoctoral position is a time-limited merit-based employment focused primarily on research, intended as a first career step after earning your doctorate. Other For information about the processing of personal data in connection with recruitment. It is possible that an employment at KTH is classified as security-sensitive. If so for this position, a security clearance of the applicant will be conducted in accordance with the Security Protection Act (2018:585) after consent. In these cases, approval following a security clearance is a prerequisite for employment.
