Senior Social Media Manager (f/m/d) AI-first

We are rebuilding our brand marketing AI-first: campaign, content and social in one team, with AI as the standard tool from brief to finished asset. You run the social media work for one or more of our brands (IONOS, STRATO, home.pl, Fasthosts, Arsys, World4You, Piensa): platform strategy, channel mix, formats, community. Formats and AI adaptations originate with you, and you bring agencies and creator partnerships in when volume or complexity calls for it.

Tasks

• You own the organic channels from strategy to post: platform mix, editorial plan, formats, community, for one or more brands and markets. Paid social sits with Media and Performance Marketing.
• You make campaigns and content platform-native and hold the brand together across all platforms and markets: tone of voice, claim, design.
• You build creator and influencer formats and decide which continue, which get rebuilt and which get retired.
• You do it yourself where tools, rights and quality allow it: shoot and cut a short, build a carousel, pull a language version, set up a format. Concept, format and mechanic originate with you, not with the vendor.
• You own community management including the escalation logic (when Social answers, when Support, PR or Product does), spot trends early and ship within hours.
• You work with Media and Performance Marketing every day: joint test plans, organic-to-paid, social listening, brand tracking, pre-tests. You read the results yourself and decide which hypothesis goes into the next wave.
• You build and run your own workflows and agents (platform formats, localisation, versioning, reporting), set the guardrails with Legal and Design and decide which new tools go into the standard process.
• You think in a flywheel and help build the asset library, prompt library and test history, so the team gets faster with every cycle.

Qualifications

• At least 6 years in social media, in-house, agency-side or as a creator, with at least two channels or formats you built yourself and whose numbers you know.
• Hands-on mindset: your first question is whether you can do it yourself, not who can do it for you. You have examples of taking over something that used to run externally.
• You know the platforms from practice at senior level and decide which brand shows up how on which platform.
• You judge a format on the idea and on the result, and you argue both, in front of the agency and in front of the performance team. You plan tests instead of only reading results: hook tests, organic-to-paid setups, creative rotation.
• You already work AI-first and can prove it: which tools, what output, what it saved in time or production cost. Examples from your daily work count more than certificates.
• Practice with generative image and video production (e.g. Midjourney, Flux, Firefly, Veo, Runway, Sora) and with language models (e.g. Claude, ChatGPT, Gemini). You build automations yourself, at least at the level of n8n or Make.
• You understand the logic of Media and Performance Marketing: funnel, frequency, creative wear-out, paid and organic. Several brands or markets in parallel, creator and influencer programmes, social listening and DAM systems are welcome.
• Fluent German and English.

Benefits

• Hybrid working model.
• Flexible working hours through trust-based working hours.
• At some locations a subsidized canteen and various free drinks.
• Modern office space with very good transport connections.
• Various employee discounts for activities and products.
• Employee events such as summer and winter parties, as well as workshops.
• Numerous training and development opportunities.
• Various health offers, such as sports and health courses.
