What You'll Do:
- Own a portfolio of accounts end-to-end — retention, adoption, and expansion.
- Build relationships with day-to-day and decision-making stakeholders — understand their business, not just their product usage.
- Build success plans with your Account Executive and run regular business reviews that show value delivered and next steps.
- Go technically deep enough to solve real problems in the platform, and de-risk renewals long before they land.
- Multi-thread each account and orchestrate Product, Support, and Engineering around the customer.
- Drive your customers’ active participation in our scalable content formats — onsite events, webinars, roundtables — and get them contributing, including presenting their own story.
- Turn wins into repeatable plays and feed customer signal back into product and GTM.
What We're Looking For:
- 2-4 years in B2B-SaaS Customer Success, Consulting, Account Management, or other client-facing roles.
- A track record of managing client relationships with measurable results in retention and adoption.
- Comfort with technical concepts and a willingness to build technical fluency — you don't need to code, but you should be curious about how the product works and ready to grow your grasp of cloud architecture and data concepts over time.
- An appetite for learning a broad, complex product portfolio across many different user types and use cases.
- A proactive mindset — you notice opportunities for customers to get more value and know when to flag them.
- Ownership and reliability — you follow through on commitments and thrive in a fast-moving environment.
- A steady head under pressure — a tight deadline, a customer question you don't have the answer to yet, a first-time escalation.
- Fluency in English, plus professional proficiency in at least one of the following: German, French, Spanish, Dutch, or Italian.
Job Benefits:
Substance, not slogans 2,500+ customers on the platform. BlackRock, Goldman Sachs, and Armira as investors. A product that won the European market without a heavy sales machine. None of this is hypothetical, it is what the role is built on.
Real ownership You shape your book of accounts, your topic lane, and the success-plan logic. Your account signal feeds product, pricing, and GTM. Not as a token gesture, as the actual mechanism.
AI-native team Real budget for AI tooling and a mandate to set the frontier on AI-augmented enterprise CS. We don’t bolt AI on; AI is how the team operates.
Senior leadership access A structured CS organisation with senior leadership support, an Academy team for customer enablement, and Professional Services that own onboarding cleanly.
The practical bits
- Competitive base salary plus a CS performance component tied to retention, expansion, and adoption KPIs.
- You’re based either in the office (Munich or Madrid) or on-site with customers across Europe, with the flexibility to work up to 2 days per week from home.
- Career path into CS Team Lead, CS strategy, or strategic account roles in the broader commercial organisation.
