(Senior) Customer Success Manager (f/d/m)

A definitive shift is currently happening. Corporates across the globe are no longer just reporting on sustainability; they are actively investing in it as a core financial and strategic asset.

• Partner with Sales and Marketing to execute strategic client communication campaigns that keep complex corporate networks, suppliers, and subsidiaries engaged long-term.

What you need to succeed

• 2–7 years of experience in client-facing operations, enterprise account management, or B2B customer success, with a track record of driving flawless post-transaction execution.

• Exceptional project management capabilities and operational discipline, with the proven ability to structure complex deliverables and manage a broad, dynamic scope of responsibility.

• Highly analytical mindset with a strong command of data and reporting, capable of translating complex metrics into polished, reusable client-facing assets and frameworks.

• Polished verbal and written communication skills, with the executive presence required to confidently engage and align senior external stakeholders.

• Operational proficiency with Salesforce and modern CRM architecture to maintain rigorous data alignment across client management platforms.

• Fluency in German is a plus, alongside a foundational understanding of carbon markets, sustainability regulations, or evolving corporate climate frameworks.
