Software Engineer in the area of Machine LearningThe Swiss National Supercomputing Centre (CSCS) develops and operates a high-performance computing and data research infrastructure that supports world-class science in Switzerland. Its user laboratory is available to domestic and international researchers in academia, industry, and the business sector. The centre is operated by ETH Zurich and has offices at its data centre in Lugano and in Zurich.For this position the preferred work location is Zurich, but it could also be Lugano.Project backgroundWe are seeking a driven software engineer to work at the intersection of machine learning and high-performance computing, tackling complex, open-ended challenges to deliver scalable solutions. You will design and optimize a software-defined infrastructure that enables cutting-edge AI/ML projects in a high-performance and data-intensive environment.We value technical excellence, curiosity, and the ability to learn and grow, rather than a initial perfect match of a skills checklist. If you are motivated to make an impact in this space but do not meet all requirements, we still strongly encourage you to apply.We are offering a contract initially limited to two years, which will provide theopportunity to contribute to a fast-evolving AI landscape in which CSCS plays a key role and to support high-impact initiatives both nationally and internationally. This includes contributions to the Swiss AI Initiative and similar programs, such as lending support for the development and release of the Apertus models.The initial two-year contract could potentially be extended or even become permanent.Collaborate with researchers and users to understand and solve complex, real-world problemsContribute to AI/ML projects, including large language model training, inference, fine-tuning, and HPC-accelerated workflowsDevelop, maintain, and optimise software and systems, from core libraries programming to scripting and automationTake ownership of high-impact tasks and see them through to completion while maintaining effective communication with stakeholdersJump into ill-defined problems, explore solutions, and learn along the wayProfileWe welcome engineers with diverse backgrounds who are eager to contribute to our mission. We are primarily looking for strong technical foundations, sound engineering judgement, and the ability to bridge gaps across domains. Curiosity, adaptability, willingness to learn on the job, and potential for growth matter more to us than a perfect initial match of technical requirements.The technologies listed below illustrate the breadth of our stack and areas of interest.
