Machine Learning Engineer (LUMI AI Factory)

Would you like to develop software for the highest level of AI supercomputing?

LUMI AI Factory powers the most ambitious development projects ranging from sensor fusion of physical AI system to large public collaborations to develop the next generation of European large language models.

At CSC, we offer unparalleled growth opportunities, a supportive and inclusive environment, and the chance to work on the future of research and learning. Join us today!

We are now looking for a Machine Learning Engineer to develop and maintain containerised AI software environments, providing LUMI AI Factory customers access to all the tools they need for running demanding AI workloads. You track user needs and the development of core AI libraries in order to gain a strong understanding of the AI software ecosystem. Based on this understanding, you work to deliver a comprehensive environment optimized for the LUMI supercomputer and, in the future, LUMI-AI supercomputer.

You will be part of a small technical team focused on developing and providing a relevant tool offering. The current software environment is comprised of a collection of PyTorch-based AI containers for the LUMI supercomputer. As a Machine Learning Engineer, you extend the coverage of the environment to additional deep learning frameworks, such as TensorFlow and JAX, as well as mixed workflows involving both deep learning as well as computational simulation libraries. The work will also include creating and implementing maintenance practices for these tools. A major part of the work is debugging issues resulting from a mix of quickly evolving AI libraries and a unique supercomputing environment. Part of your duties will also be interacting with the user support team as well as the technical teams in other international AI Factory partner organizations.

You also participate in designing containerised workflows to streamline the use of AI on supercomputing systems. Containerised workflows combine pre-built container images, custom software, documentation and pre-tested models and examples. As a Machine Learning Engineer, you develop containerized workflows for specific tasks in fields like natural language processing and computer vision.

Additionally, you contribute to the development of a testing framework for the containerized software environment. This involves designing and running multi-node tests to validate updates to the AI stack, ensuring compatibility with real-world use cases, and increasing overall test coverage. Experience with training models at multi-node scales is considered a strong merit.

This is a fixed-term, project-based role until February 29, 2028.

What we expect

We expect you to have experience in technical work involving software installations and containerized applications, as well as a strong interest in problem solving. Knowledge of supercomputers, deep learning as well as container runtimes and orchestration is appreciated. Good communication skills in English are essential for working in an international multi-partner project.

To be successful in the role, you need:

• Experience of building containerized applications

• Knowledge of running software on supercomputers

• Understanding of AI training and inference

• Software maintenance experience

We also value:

• MLOps knowledge

• Specific technologies used on LUMI (e.g., Singularity containers, ROCm, Slurm, HPC communication libraries)

• Master's degree in a relevant field (e.g. machine learning/data science, computer science)

What we offer

At CSC, our employees enjoy a wide range of benefits designed to support both their professional and personal lives. We offer flexible working hours and the option for remote work, making it easier to balance work and daily life. Our comfortable workspaces in Keilaniemi, Espoo, and Renforsin Ranta, Kajaani, are designed to facilitate both teamwork and tasks that require quiet concentration.
