Media Strategy Director in London

Prospect are the fastest growing global media agency network of the last three years, accelerating brands who are shaping the future. We are proud to partner with some of the world’s biggest icons, such as Kering, BMW, Netflix, Salesforce, eBay, Ferrero, Carlsberg and more. We are always looking for brilliant talent to join our team and encourage you to reach out for a chat. A restless attitude and performance mindset is essential!

Purpose of the Role

A valued member of iProspect Global, this role is to steer the global strategy and planning of two large global clients. The first is a house of brands, (some of the world’s most prestigious household names), and the second is a branded house (a FTSE 100 tech company). Very different categories, clients, business contexts and audiences, but a simple mission across both - use your strategic clarity and media excellence to unlock growth.

Your job is to keep raising the bar of excellence, asking the right questions - where are we now? Where do we want to be? How are we going to get there? are we getting there? Where can we take this brand next to win?

In addition to these two primary client responsibilities, there will be opportunities to participate in new business pitching, craft programmes and agency life.

• Set the strategic direction across campaigns
• Ensure the media rationale aligns with strategic objectives, drives measurable outcomes, and leverages best-in‑class planning tools for accuracy and efficiency.

• Oversee best‑practice planning standards, ensuring seamless activation and continuous improvement across campaigns.
• Motivate specialists in strategy, digital, measurement, innovation, and reporting to collaborate effectively and deliver exceptional results.
• Drive insightful reporting that resonates with senior stakeholders, identify innovation opportunities using data‑driven insights, and enhance BAU performance.
• Maintain high standards in account management, serve as a role model for junior team members, and run processes that keep projects on track and efficient.

Qualifications + Skills

• Strong e‑commerce knowledge
• Extensive media planning experience with strong skills across all media channels, including multi‑market planning and/or B2B campaign experience.
• Proven ability to work collaboratively across teams and maintain strong client relationships in complex, multi‑stakeholder environments.
