Customer Success SMB (Internship)

At Ezus, we’re building a scalable Customer Success model for hundreds of travel agencies. Your mission will be to help us design it.
To do that, you’ll first spend time with customers, understand what drives adoption and retention, and then transform those learnings into automated journeys, programs and playbooks that scale.

This end-of-studies internship is designed as a long-term opportunity: you’ll start by learning Customer Success fundamentals on the ground, before progressively taking ownership of scalable programs and automation initiatives. If things go well, the ambition is to grow the role together beyond the internship.

Your missions

Phase 1 — Learn from customers (first 4-6 months)

• Own the onboarding of new clients and ensure their activation on the platform

• Manage a portfolio of Small and Low-Touch accounts: usage tracking, satisfaction, renewals

• Identify recurring friction points and critical moments in the customer journey

• Contribute to documentation: Help Center, guides, educational content

Phase 2 — Build for scale (as you grow) ⚙️

• Design automated customer journeys (onboarding, adoption, retention, expansion) grounded in what you’ve learned on the ground

• Build and run segmented communication campaigns based on customer behavior and usage

• Host webinars and create educational content to accelerate product adoption

• Define and monitor customer health signals to prioritize high-impact actions

• Structure playbooks so that best practices scale across the team

This is a newly created role and a unique opportunity for an end-of-studies intern to help shape how Customer Success scales at Ezus. Nothing is fully built yet. You’ll have the opportunity to shape how Customer Success scales at Ezus and leave a lasting impact on the way we support our customers.
