Senior Manager Media Strategy & Planning (f/m/d)

At IONOS, the leading European provider of cloud infrastructure, cloud services and hosting services, you will work together with a wide range of teams. We are characterized by open structures, a friendly working culture and flat hierarchies with a strong team spirit. We firmly believe that work and fun are compatible, and offer you the right environment for this. Our constant growth means that we are always looking for new colleagues. Become part of IONOS and grow with us.

You have spent the last years operating at the highest level of media strategy — cross-channel, data-driven, with real impact on brand growth and performance. Now you want the next step: not just optimising media planning, but rethinking media planning from the ground up.

 With us, you take strategic ownership of media strategy and performance optimisation — and at the same time you shape the build-out of a fully AI-powered media optimisation infrastructure. You are the person who defines how media investments will be planned, optimised, and measured in our organisation in the future.

• Develop the overarching media strategy and cross-channel media orchestration across all relevant channels (Linear TV, CTV, Online Video, Programmatic, Paid Social, Digital Audio, Display, Print).
• Optimise media investments across markets, channels, brands, and products with a clear brandformance mindset.
• Drive strategic planning and performance optimisation of TV campaigns (Linear & CTV), including tools such as XAD Spoteffects.
• Define, design, and build a fully AI-powered media optimisation infrastructure — spanning from planning and activation through to reporting.
• Select and integrate AI tools and agents into the media workflow, establishing the KPIs, guardrails, and optimisation logic they operate within.
• Evolve our attribution and measurement framework, including Media Mix Modelling (MMM), multi-touch attribution, and incrementality testing.
• Manage external media agencies and negotiate terms and campaign deals with agencies and ad sales partners.

Qualifications

• You have 6+ years of experience in strategic media planning, gained either agency-side or in-house.
• Proven experience in cross-channel media planning balancing brand building and performance in equal measure.
• Deep know-how in TV planning and TV performance optimisation (Linear & CTV), including hands-on familiarity with SpotEffects or comparable tools.
• Strong understanding of Programmatic, Paid Social, Online Video, and digital brand awareness channels.
• Solid experience with Media Mix Modelling (MMM) and modern attribution methodologies.
• Hands-on experience incorporating AI tools (such as Claude, Gemini, ChatGPT, Perplexity, n8n, or similar) into your strategic daily workflow, with clear ideas on how these technologies reshape media planning.
• Demonstrated experience managing media agencies and leading negotiations with ad sales partners.
• Strong strategic thinking combined with a hands-on, proactive mentality.
• Fluent in English; very good German is a strong plus
