SUMMER TRAINEE 2026: HPC for Digital Twins of Earth/Climate

Just an office job? Only if you ignore the impact.

Are you looking for a summer job that offers more than just a desk and a screen? At CSC, we have dozens of summer positions open for students from various fields who want their work to make a real difference. With us, you’ll get to build your career, work on meaningful projects that impact society, and gain valuable experience with cutting-edge technology and expert services. Our Summer Xperience program connects trainees through networking events and shared activities, helping you build contacts that last.

We are looking for a Summer Trainee to join the Digital Twin Technologies (DTT) group in Espoo. Our team develops Digital Twins of Earth to tackle some of the grand challenges our planet is facing, such as climate change. The digital twins that we develop consist of climate models and other software that utilize state-of-the-art supercomputing platforms, including the LUMI supercomputer hosted by CSC in Kajaani (https://www.lumi-supercomputer.eu).

As a summer trainee, you will participate in Digital Twin projects that aim to produce actionable information on climate change, linked to the EU’s Destination Earth initiative (https://destination-earth.eu). One of these projects is TerraDT (https://terradt.eu), which develops new Digital Twin components to improve the description of land surface, cryosphere, and aerosol particles in the Destination Earth Digital Twins.

In this role you will:

• Contribute to optimization and testing of different model and application codes as part of CSC's Digital Twin projects

• Perform performance analysis and optimize numerical model components and supporting applications on the LUMI supercomputer

• Set up and implement component-level tests for different models and applications

• Document your work and contribute to project reports

What we expect:

• Basic knowledge of Linux and programming experience (at minimum Python, other languages are an asset)

• Fluency in English, both written and spoken

• Experience in climate or other physical modeling is considered an asset

• Most importantly, we value your curiosity and enthusiasm to learn!

• A suitable candidate would be a student close to finishing their M.Sc. in natural sciences (e.g., computer science, physics, geosciences)

What we offer?

At CSC, you’ll be part of something that matters. You’ll work on projects that support research, education, and the digital future of society – and you’ll learn a lot along the way.

Our Summer Xperience program brings trainees together for networking and fun activities, helping you build contacts that last beyond the summer. You’ll also enjoy flexible working hours, the option for remote work, and inspiring workspaces in Keilaniemi, Espoo, and Renforsin Ranta, Kajaani. Employees can also take advantage of a lunch benefit during the workday.

Our summer trainees usually work from May to August, but other dates are also possible. The duration is usually 3–4 months.

Traineeship is paid. The salary depends on the stage of studies but is at least 2100 €/month.

Please send your application by 15.2.2026. Apply as soon as possible – we start interviewing already during the application period and selections will be done right after we have found suitable persons. We aim to inform all applicants about the progress of the recruitment by the end of March 2026 at the latest. Reviewing applications takes time, so there is no need to worry if you do not hear from us immediately.
