EMEA Customer Success Manager

Gravitee is a 2025 Gartner® Magic Quadrant™ Leader, on a mission to govern the world’s intelligence.

We deliver the industry’s most advanced platform for Any API, Any Event, and Any AI Agent, trusted by global leaders like Michelin, Roche, and Blue Yonder.

  • The Mission: We are bridging the gap between traditional tech and the new frontier of AI Security.

  • The DNA: We hire "Hold Nothing Back" individuals - passionate professionals who want to redefine how the world interacts with technology.

This is a fixed-term position covering a maternity leave, offering a unique opportunity to manage some of our most prestigious enterprise accounts during a period of rapid AI-driven expansion

The Role

AI is rewriting the rules of business, and Gravitee is at the center of that transformation. As our Customer Success Manager (12-Month FTC), you will step into a high-impact role, acting as the strategic advisor and project lead for an established portfolio of enterprise accounts.

You’ll guide customers from their initial launch through to long-term success and renewal. Given the technical nature of our platform and the complexity of enterprise environments,, we’re looking for a partner who blends technical curiosity with disciplined project management to ensure every milestone is met and every goal is realised.

What You’ll Be Doing

At Gravitee, impact isn’t abstract - it’s visible and global. In this role, you will:

  • Strategic Account Management: Own the long-term success and retention of a diverse portfolio of enterprise customers across EMEA, ensuring a seamless transition and consistent high-level service.

  • Project-Led Onboarding & Success Planning: Lead customer "Success Projects" by executing clear milestones, technical requirements, and timelines to ensure rapid time-to-value.

  • Risk Management & Mitigation: Proactively identify project "blockers." Use established project management frameworks to track, escalate, and resolve risks before they impact customer health.

  • Cross-Functional Orchestration: Act as the project lead between the customer and Gravitee’s internal teams (Product, Engineering, and Support) to deliver on custom requirements or complex migrations.

  • Value Realization & QBRs: Conduct regular Quarterly Business Reviews (QBRs) that demonstrate ROI through data-driven reporting and project status updates.

  • Renewal Management: Partner with Account Executives to ensure a seamless renewal process, maintaining our commitment to low churn.

Your impact will be visible, measurable, and global.

Essential Skills

  • 3+ years in a CSM or Account Management role within a B2B SaaS environment (API, DevOps, or Infrastructure space preferred).

  • Proven experience managing complex technical projects. Familiarity with methodologies such as Agile, Waterfall, or Prince2 is highly desirable.

  • Ability to confidently discuss technical concepts (APIs, JSON, Cloud Infrastructure) with developers and architects.

  • Exceptional presentation and negotiation skills; able to translate complex technical milestones into business value for C-level stakeholders.

  • Comfort working in a fast-paced, high-growth environment where you can quickly adopt evolving processes and tools.

Who Thrives Here

Our growth is powered by people who bring passion to their craft, professionalism to their execution, and a commitment to excellence. You’ll thrive here if you:

  • Care deeply about high-quality output and brand clarity.

  • Are curious, adaptable, and energized by the fast-moving AI landscape.

  • Take full ownership of your projects from concept to completion.

  • Value a culture of openness, collaboration, and constant evolution.

Bonus Points: Experience in SaaS, AI-enabled systems, or open-source communities, but a "growth mindset" and curiosity matter most.
