Join One Portal and Lead Data-Driven Decisions at Scale!

One Portal is a pan-European B2B eCommerce and self-care platform transforming how business customers interact with Deutsche Telekom across multiple markets. Behind the platform stands data — complex, cross-country, and rich with opportunities to drive real business impact.

We are looking for senior data professionals who want more than dashboards. In this role, you will shape how data is used across the product and markets: from defining metrics and analytical frameworks, through advanced analysis and experimentation, to influencing strategic product and business decisions.

As a Senior Data Analyst you will work at the intersection of product, technology, and business. You will collaborate with product owners, engineers, UX, and local market teams, helping them move from intuition to evidence-based decisions. Your insights will directly influence roadmap priorities, adoption strategy, customer experience, and platform scalability across Europe.

This is a role for someone who enjoys ownership and leadership — setting standards, mentoring others, and building a strong data culture in an international, agile environment. You will deal with large-scale, multi-market data, complex user journeys, and real-life business problems, not theoretical exercises.

If you are passionate about turning data into action, influencing decisions at scale, and building data maturity in a growing international product — One Portal is the place where your impact will be visible and meaningful.

Apply and help us build a truly data-driven B2B platform across Europe.

In our recruitment process, you can expect honesty and transparency. We consider each candidacy carefully and fairly, without any exceptions. We don’t look at your race, skin color, sexual orientation, gender identity, nationality, disability status, beliefs, appearance or religion. It’s your competencies that count.
