Senior Marketing Manager SEA (m/w/d)

• You own our SEA accounts end to end, from strategy and budget planning across Google Ads and Microsoft Ads through to day-to-day optimisation
• You continuously develop account structure, keyword sets and ad copy, and keep testing assets, bidding strategies and landing pages
• You manage Smart Bidding, Performance Max and Demand Gen based on data, with a clear focus on lead quality rather than raw lead volume
• You build out our measurement foundation: GA4, Google Tag Manager (including server-side), Consent Mode v2 and offline conversion imports from the CRM
• You produce forecasts, reporting and clear recommendations, making the channel's contribution to revenue transparent
• You work closely with Sales, Content/SEO and Product, covering everything from audience definition to landing pages and lead handover
• Your success will show in: CPA/CPL and lead quality throughout the funnel, ROAS and channel contribution to new business, plus budget and forecast accuracy

• Several years' experience in SEA or performance marketing, ideally in-house in a platform or SaaS environment, or agency-side with a B2B focus
• A proven track record of independently managing substantial monthly budgets
• Confident with Google Ads, Microsoft Ads, GA4, Google Tag Manager and reporting tools such as Looker Studio
• A solid grasp of conversion tracking, attribution and data quality — experience with server-side tracking, Consent Mode v2 or offline conversions is a real plus
• The ability to pull, combine and analyse data from different sources (Google Ads, GA4, CRM exports) on your own, even without ready-made reporting pipelines
• Experience with offline conversion tracking via CRM systems (e.g. HubSpot), from data modelling through to uploading into Google Ads
• An analytical, hypothesis-driven way of working and a genuine enjoyment of backing decisions with numbers
• An interest in bringing AI and automation into campaign management and marketing processes
• Fluent German and good English

• A role with real responsibility and direct impact on our growth
• Full ownership of the channel, the budget and the setup — quick decisions instead of endless approval loops
• Flexible hybrid working
