Tasks

In Sales Controlling – part of the Corporate Cost Controlling team – you can expect a dynamic, open-minded environment: We analyze sales and marketing KPIs group-wide across all IONOS Group brands and ensure that month-end closing tasks are handled reliably.

  • Analyze sales, marketing, and customer KPIs group-wide and prepare them for management and the sales team.
  • Handle month-end closing tasks within Sales Controlling – such as reconciling revenue data, performing target-vs-actual comparisons, and contributing to the timely completion of financial statements.
  • Support sales reporting, forecasting, and sales planning – group-wide across all IONOS brands.
  • Gain hands-on experience with AI-powered tools live in action and actively contribute to their further development.
  • Collaborate with colleagues from Sales and Finance across various locations and gain experience in an international corporate environment.

Qualifications

  • Ongoing studies in Economics, Business Administration, Business Informatics, or a related field – ideally with a focus on Controlling or Finance.
  • Proficiency in Excel; initial experience with Power BI, SQL, or AI-powered tools is a plus, but not required.
  • Analytical thinking, an affinity for numbers, and a structured, reliable way of working – especially for recurring month-end closing tasks.
  • Business-fluent German skills and good English skills for working within an international team.

To process your application, we require an up-to-date transcript of records from your university.
