* Lead regular business reviews, presenting insights with clarity and confidence
* Identify upsell and expansion opportunities across accounts
* Collaborate cross-functionally with Sales, Product, and Marketing to maximise outcomes
What We’re Looking For
* Several years of SaaS customer success experience (essential)
* Proven track record in a start-up or scale-up environment
* Deep understanding of CSM frameworks, metrics, and best practices
* Commercially astute, with direct experience driving adoption, renewals, and expansion
* Excellent stakeholder management and presentation skills
* Structured, data-driven, and comfortable talking in terms of KPIs and ROI
* Ambitious and proactive, with the drive to succeed in a high-growth environment
Why You’ll Love This Role
* Join a high-performing, fast-moving SaaS team with real growth ambitions
* Autonomy and influence in how you manage and grow your accounts
* Hybrid working (1 day a week in London office)
* Competitive package with commission, pension, and wellbeing support
* Clear progression opportunities as the company continues to scale
If you’re a metrics-driven SaaS CSM with the experience, ambition, and credibility to make an impact—we’d love to hear from you.
