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.

Tasks

• 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
