Senior Customer Success Manager (Enterprise)

Effectory is Europe's leading employee feedback solution. With our platform, HR and management collect employee feedback throughout the employee journey. This feedback is transformed into people analytics that informs strategies to boost productivity, engagement and retention. Built on 25 years' experience, our 200 specialists in Amsterdam and Munich support more than 800 organisations in 70+ countries. Now more than ever, HR is an integral part of business strategy – which is why our feedback solution is tailor‑made for strategic HR.

Our mission: to improve the working world by giving employees a voice and making sure their feedback has an impact.

As an Enterprise Customer Success Manager, you are the ultimate value owner and strategic partner for Effectory's highest‑tier, most complex accounts. You move beyond tactical management to become a trusted advisor, ensuring that Effectory is deeply embedded in each customer's long‑term business strategy and digital ecosystem.

Your mission is to architect success for your portfolio – adoption to measurable results and advocacy – by translating complex business challenges into measurable product value. You are responsible for driving high‑impact adoption and securing long‑term retention through multi‑threaded partnerships and a deep understanding of the HR and people analytics landscape.

• Effectory's Enterprise Customer Success team partners with our largest customers across Corporate (e.g. IKEA, AS Watson, PostNL), Healthcare, and Education. From the moment onboarding wraps up, you build the foundation for long‑term adoption – establishing multi‑level relationships that secure strategic buy‑in early and keep it strong. Proactively translate technical usage data into compelling ROI narratives, demonstrating how Effectory drives impact across the full HR and engagement funnel – from adoption to long‑term advocacy.
• Achieve a high Net Renewal Rate (NRR) by maintaining customer health, addressing risks proactively, and identifying opportunities to expand customer usage.
