Group Account Director (Portfolio Lead), any UK in London

This is a senior portfolio leadership role responsible for leading, growing and managing a complex multi-client, multi-market portfolio across the Technology sector.

Reporting to a SVP Client Engagement, the role will act as the senior lead for a client portfolio in Europe, providing client continuity, commercial ownership and regional leadership. The position is UK based, reflecting the concentration of the portfolio's highest client spend and the need to provide direct leadership to our teams, strengthen market presence, drive growth across emerging sector opportunities, and ensure effective development of our creative proposition within the UK market.

The role carries accountability for client strategy, commercial performance, growth delivery, senior stakeholder engagement and leadership of senior account teams across the region. You will bring significant experience managing large-scale, multi-market client portfolios, ideally with exposure to $75m+ annual revenue or equivalent commercial complexity.

This is a senior leadership role, but it requires a hands-on operator. You'll need to be comfortable moving between strategy and execution, working directly with account leads, clients, finance, operations and delivery teams to remove blockers, protect performance and convert opportunities into growth. The position offers a rare opportunity to take senior ownership of a Technology portfolio at a pivotal stage of HH Global’s growth.

This UK-based role will provide the regional leadership required to protect and grow key client relationships, strengthen commercial performance, and support the next phase of Technology sector expansion.
