You will join a team working on HELM’s global data platform and collaborate with internal IT teams, business stakeholders, and external partners. As you build experience, you will gradually take on broader ownership and responsibility.

Requirements

• A degree in Computer Science, Business Informatics, Data Science, or a similar field/qualification.
