An independent, modern and agile B2B marketing agency is looking for a strategic, relationship-led Senior Account Director / Head of Client Services who loves the pitch process and thrives on shaping marketing strategy for clients. This role is perfect for someone who gets energised by inbound opportunities, enjoys thinking creatively about “how we win this,” and takes pride in being a trusted partner to clients.

Leading the pitch process for all new inbound opportunities—shaping the story, approach, and strategy to win work.

Building and growing strategic relationships across multiple client stakeholders.

Acting as a senior consultant—guiding clients through integrated marketing strategy across digital, content, comms, brand, campaigns and more.

Identifying upsell and cross-sell opportunities by understanding client challenges and recommending high-value programmes.

Providing clear strategic direction to the delivery team, who handle all execution.

Working closely with the senior leadership team on commercial planning, pipeline development, and quarterly objectives.

Translating insights, challenges and ambitions into actionable strategic recommendations.

Ensuring all client programmes drive measurable business outcomes, not just marketing outputs.

A relationship-first approach—comfortable partnering deeply with clients, not pushing for transactions.

Proven experience growing accounts through insight, creativity and value delivery—not cold sales.

Ability to brief, lead and influence internal teams with clarity and purpose.

Work in a modern, agile agency that partners deeply with clients across the full marketing mix.

Enjoy a steady flow of inbound opportunities—no cold hunting involved.

Become a key strategic partner shaping client success and agency growth.
