Performance Marketing Expert (Customer Success)🇨🇭

About the job

Location: Zurich

💚 About us

Our mission is to help marketing teams unlock their full growth potential with AI. Our AI-powered attribution creates genuine transparency and shows how digital advertising investments impact across various channels. Based on this, we optimise budgets so our clients can sustainably increase their profits. We support leading European brands from e-commerce, telecommunications, banking, insurance & energy, as well as many other sectors, in making their marketing smarter, more efficient, and more effective.

🚀 Your mission

As a Customer Success Manager, you are the central contact person for our German-speaking clients and empower them to fully exploit the potential of our AI-based platform. You guide them away from manual, Excel-based processes towards a new, data- and AI-driven way of working. You build strong relationships, provide competent advice, and ensure that digital marketing teams exceed their performance goals with the power of our AI platform.

🧑💻 Your tasks

• Independent management of customer accounts (from onboarding through optimisation to contract renewal)
• Analysis of cross-channel performance data together with the client (Google Ads, Meta, TikTok, Snap, etc.)
• Identification of optimisation potentials and concrete recommendations for action
• Advising our clients on performance marketing topics and best practices for AI implementation
• Close collaboration with account managers for the strategic development of customer accounts
• Close collaboration with our product & ML teams to further develop our platform

🎯 What you bring

• Several years of experience (>3 years) in performance marketing (agency or advertiser side); initial experience in a small company/startup or scale-up is an advantage
• Strong communication skills and genuine enjoyment of customer contact
• A proactive mindset and drive to advise clients with high-quality solutions
• Curiosity about AI and automation. You don’t have to be a developer but should be eager to work smarter with AI
• Very strong analytical skills and confidence in handling data. Experience with incrementality testing, causal impact analysis, A/B testing or econometrics/MMM is an advantage
• German at native level and business fluent English
• Willingness to travel occasionally (client meetings, team events)
