Becoming a Mentioneer means you’ll be joining a driven team, with big plans, at a genuinely exciting time for our business.

As an Enterprise Customer Success Manager , you will own the post-sale relationship with our most strategic accounts; large, complex, global organisations with multi-stakeholder buying committees, sophisticated technical environments, and six-figure-plus annual contracts. You will be the trusted advisor and executive sponsor these customers rely on to realise value, expand their use of the platform, and become champions of our product inside their organisations.

This role demands someone who is genuinely comfortable operating at the most senior levels of a large enterprise. You will spend the majority of your time on-site with customers, building relationships across the C-suite, challenging conventional thinking, and guiding large organisations through significant changes in how they approach marketing, customer acquisition, and advocacy.

This is not a remote-first, reactive role. It requires presence, gravitas, and the ability to navigate the complexity and politics that come with managing relationships inside large, matrixed organisations. You must be willing and able to travel 30% or more of your time to customer locations across the UK and internationally.

• Develop a deliberate executive engagement plan for each account, mapping influence, identifying champions, and building relationships that exist independently of any single point of contact.
• Lead and facilitate executive business reviews (EBRs) that speak the language of business outcomes, not product features. Connecting platform ROI to board-level priorities.

Navigating Large Enterprise Organisations

• Chair and lead complex, multi-workstream programmes within large enterprise accounts, coordinating across CRM, Marketing, Customer Experience, Data, and IT teams simultaneously.
• Navigate the internal politics, competing priorities, and slow decision-making cycles that characterise large organisations, building coalitions of support and maintaining momentum through change.
• Identify and develop internal champions at multiple levels of the organisation, ensuring adoption and advocacy is not reliant on a single sponsor.
• Manage complex stakeholder matrices with diplomacy, patience, and strategic intent, knowing when to elevate, when to push, and when to listen.

Account Growth & Revenue

• Own Net Revenue Retention (NRR) and Gross Revenue Retention (GRR) targets for your portfolio of enterprise accounts.
• Proactively identify and qualify expansion opportunities, including upsell, cross-sell, and new use cases.
• Lead commercial negotiations for renewals and multi-year contract expansions, building a compelling business case grounded in demonstrated value.
• Understand the procurement and budget cycles of large enterprises and plan your commercial engagement accordingly.

Value Realisation & Onboarding

• Lead the onboarding of new enterprise customers, orchestrating cross-functional internal teams (Operationss Support, Product) to deliver fast, measurable time-to-value.
• Co-develop…
