Customer Success Manager (m/f/d)

We're looking for a Customer Success Manager to ensure our clients are not only successful in deploying atmio but are also empowered, engaged, and expanding their use of our platform. You'll take the lead on relationship management, retention, and upsell opportunities, working closely with our software and sales teams to deliver exceptional service and surface critical feedback. You'll join a small but growing team — this is our second hire in Customer Success — and help define the playbook, structure, and processes that will scale with us. Key Responsibilities 🎯

• Relationship & retention: Build strong, trust-based relationships with key customer stakeholders, monitor account health, and drive renewals and expansions

• Voice of the customer: Gather insights and feedback, helping product and software teams prioritise improvements based on real customer needs
• Operational excellence: Contribute to internal CS tooling, documentation, and scalable processes (including health monitoring and onboarding flows)

• Thrive on building trust with senior B2B customers and turning great relationships into long-term successstories
• Love digging into data and processes to drive retention, identify upsell opportunities, and improve the customer journey
• Enjoy taking ownership, moving fast, and creating structure where there is none — especially in a growing startup environment
• Get energy from cross-functional collaboration and turning customer feedback into actionable improvements
• Communicate clearly, handle tough conversations with empathy, and stay calm under pressure
• Want your work to directly support climate impact and be part of a mission-driven, high-performance team 🌍
