About the role

Junior Customer Success Manager for Activation in DACH responsible for onboarding and activating German-speaking customers, setting up AI assistants, testing, and going live with customer setups. Onsite role in Vienna with strong emphasis on hands-on onboarding, configuration, and ensuring customers move from signing to active use.

Responsibilities

  • Run onboarding calls with new DACH customers and set up their AI assistant together with them
  • Translate each customer’s business into a working setup: prompt, knowledge base, call transfers, notifications and integrations
  • Test and fine-tune assistants until they’re ready to go live, so customers don’t get stuck in “almost done”
  • Help customers connect their phone system and get call forwarding running
  • Follow up with customers who signed but aren’t active yet, and get them over the line
  • Become a power user of the platform: learn how each feature works and which setup fits which use case
  • Bring patterns and friction points from onboardings back to Product and CS to improve templates, guides and the product
  • Hand activated customers over to Customer Success with a clean setup and clear notes
  • Track your onboardings and activation results in HubSpot

Qualifications

  • 0–2 years of experience in a customer-facing role (onboarding, support, CS, sales, hospitality or customer service) or a strong graduate profile. Internships count.
  • Native or C2 German, fluent English
  • Basic technical skills and real curiosity about how things work. You enjoy clicking through a platform until you understand it, and you’re not scared of webhooks, APIs or phone settings.
  • You like solving puzzles: “How do I build this for this customer?”
  • You explain things simply and stay patient with non-technical customers, by phone or video
  • Structured: you can run several onboardings in parallel without dropping anything
  • Hands-on and quick to learn. You take initiative and don’t wait to be told what to do.
  • Willing to relocate to Vienna
