Senior Account Manager

Senior Account Manager

Kingston Upon Thames £100,000 OTE

We're working with an established B2B marketing/tech business that are looking for 2 Senior Account Managers to take ownership of a portfolio of their most valuable, high-spend enterprise accounts.

This isn't a role to grow into - it's a role for someone who can walk in and immediately start protecting and growing revenue across complex, senior-level client relationships.

Why this role, why now

The business has recently restructured its Account Management and Customer Success functions, splitting commercial ownership from day-to-day delivery. That means this role is free from operational drag - no ticket-chasing, no reactive admin - just commercial ownership, strategic growth, and senior stakeholder relationships. A dedicated Customer Success team handles execution, so you can focus entirely on revenue.

The opportunity

This is a business that is moving quickly, with significant revenue currently sitting across high-spend accounts that need proactive, senior ownership. They're looking to make a fast decision for the right person - someone who can start adding impact from week one, not month six.

What you'll own

• Renewal strategy, negotiation, and risk management - no unplanned losses
• Proactive upsell, cross-sell, and growth conversations, backed by strong commercial cases
• Senior/exec-level client relationships - positioning as a strategic partner, not a supplier
• Key partner relationships leveraged to unlock client value and revenue
• Commercial rollout and adoption of new products, tools, and AI solutions across your portfolio

What good looks like

• You'll always know the status of every account: risk, growth, next move
• You'll run structured, planned conversations - not reactive servicing
• You'll know how to delegate delivery to a CS team without losing control of the account
• You're comfortable in the room with senior stakeholders - including face-to-face and client entertainment settings

What you need to be successful as the Customer Success Manager

• Experience as a Senior Account Manager or, Account Director working within client services, or commercial client-facing roles - ideally media, recruitment, advertising, or B2B agency
• A track record of owning enterprise relationships and hitting retention and growth targets
• Strong commercial acumen - pricing, margin, and business case-building, independently
• Confidence running and controlling renewal negotiations with senior stakeholders
• Experience working alongside a dedicated CS/delivery function, and knowing how to let it do its job
