Customer Success Manager

The Customer Success Manager is responsible for driving customer value realisation, retention and expansion within Celerity’s growth segment customer base. You will own the customer lifecycle from onboarding through to advocacy, building and maintaining strong relationships that secure renewals, generate expansion opportunity and make a positive impact on Net Revenue Retention (NRR) and our Net Promoter Score (NPS).  Working closely with the Head of Customer Success, Sales, Account Management, Marketing, Technical and Delivery teams, you will manage a portfolio of 50-75 growth segment customers, ensuring they realise value from their investment and achieve their business objectives.

You will play a critical role in shaping Celerity’s evolving Customer Success function, driving process development, and contributing to the team’s positive image and reputation both within Celerity and externally.

The ideal candidate will have previous experience in a customer success, account management or customer-facing role within B2B software, technology or professional services, driving customer retention, expansion and Net Revenue Retention.  You should have a strong understanding of SaaS and subscription business models, including key metrics (NRR, GRR, churn, NPS), managing customer life cycles and use of CRM and sales tools (Salesforce, Hub Spot or similar).  

You will demonstrate commercial acumen and excellent relationship and stakeholder management alongside the ability to manage multiple priorities in a fast paced environment.

This is an excellent opportunity for a self-motivated, commercially-minded professional who thrives in a dynamic, fast-growing environment. You’ll be part of a small, high-performing Customer Success team with genuine autonomy, clear ownership and the chance to shape how customer success operates at Celerity as we scale. You’ll work closely with technical and commercial teams across the business, gaining exposure to cutting-edge technology and enterprise clients.
