Customer Success Manager (m/f/d)

About SimScale SimScale is the world's first cloud-based, AI-native engineering simulation platform. CFD, FEA, thermal and electromagnetics run together in a single browser-based environment, supported by Engineering AI that guides simulation setup, Physics AI that returns validated predictions in seconds, and agentic workflows that execute multi-step simulation pipelines at any scale. The conviction behind the platform is straightforward: every engineer should be free to explore thousands of design options, test them instantly and decide with confidence, not only the specialists who have traditionally held the CAE tools. Founded in Munich in 2012 by five engineers, SimScale is trusted today by more than 800,000 engineers worldwide, at companies including Johnson & Johnson, Mitsubishi, Magna, Toshiba, Bühler, AECOM and Zaha Hadid Architects. The role As a Customer Success Manager you own the lifetime value of a book of SimScale accounts: Commercial and High Potential customers, including some enterprise-sized names, from onboarding through renewal and expansion. You carry a renewal and expansion number, and you own it through to signature. Why this role matters The contribution of this role is crucial to SimScale's success. Every renewal protected and every expansion landed shows up directly in the company's growth, and the relationships you build determine how deeply simulation takes hold inside each customer's engineering organisation. This is also a role with room to shape things. Alongside owning your book, you will have the opportunity to help shape and continuously optimise how Customer Success works at SimScale: the customer journey, the playbooks, the segmentation and the tooling, in an international environment with a great deal of opportunity in it.
