• Coordinating with developers and operations teams to ensure system reliability.
• Participating in the lifecycle management of internal IT systems.
• Proactively identifying and mitigating potential risks in system architecture.
• Communicating technical progress and roadblocks to non-technical stakeholders.

You will often operate in a hybrid environment, balancing the need for rigorous, stable operations with the necessity of constant digital innovation.

Be prepared to talk about your past initiatives and how you solve problems in a team context.

Q: Is there a specific focus on technical versus behavioral questions? Expect a balanced mix. While you will be asked about your technical skills and background, the behavioral and competency-based questions are equally important in determining your long-term success at E.ON.
