Your Role
As Junior Customer Success Manager for Activation in DACH, you make sure every new German-speaking customer goes from “just signed” to “fonio picks up our calls every day”. You own the first weeks of the customer journey: setting up their AI assistant, testing and fine-tuning it, and getting it live on their phone line.
You’ll spend most of your time in onboarding calls with customers and inside the fonio platform. You learn how every feature works and figure out the best setup for each customer, whether that’s a dental practice in Munich, a law firm in Vienna or a car workshop in Zurich.
What to expect
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
Who We're Looking For
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 level in at least two of Spanish, Italian and French, and at least B2 in the third. Fluent English is required.
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?” excites you
First experience with no-code/automation tools (n8n, make.com, Zapier), writing prompts for AI, or a technical study background is a plus
You explain things simply and stay patient with non-technical customers, by phone or video
Structured: you can run several onboardings in parallel, across three markets, without dropping anything
Hands-on and quick to learn. You take initiative and don’t wait to be told what to do.
German is a plus, but not required
