Digital Senior Account Manager in London

We are committed to diversity & inclusion and providing equal opportunities for everyone. We are dedicated to ensuring our processes are free from any form of discrimination or bias, right from the application process to life as part of the Mediaplus UK team.

The role involves reporting to a Digital Account Director and supporting the development of junior team members. You will own and drive digital planning and activation, spanning the digital channel mix with programmatic media (Display, CTV and YouTube) at its core alongside paid social across Meta and TikTok.

• End-to-end digital planning and activation, from brief through to launch, optimisation and reporting.
• Day-to-day optimisation, testing roadmaps and bringing new platforms and approaches to the account.
• Client status calls and presentations: walking the client through plans, performance and recommendations.
• Serve as the senior point of contact pre, during and post campaign, taking ownership of the client relationship and proactively shaping the strategic direction of the account.
• Lead cross-functional collaboration with our strategy, data, insights and client leadership teams, acting as the connective tissue between channel specialists and client leadership.
• Architect brand-led planning frameworks anchored to a measurement strategy that demonstrably connects activity to the clients business outcomes.
• Actively shapes the agency’s broader offering on the account, with a clear pathway toward Account Director.

What we're looking for:

• Hands-on experience: proven track record in digital planning and activation, with the confidence to lead complex, multi-channel programmes independently, and strength in programmatic alongside a strong working knowledge of paid social.
• Brand and performance balance: experience guiding clients through full-funnel investment, from upper-funnel brand-building to lower-funnel conversion (lead generation, CPA, sales).
• Innovation appetite: keeps pace with new platforms, tools and trends, then puts them to work to solve real client challenges.
• Platform experience: hands-on with key digital ad-serving and measurement platforms (DV360, Campaign Manager, Meta Ads Manager, TikTok Ads Manager).
• Exceptional organisation and prioritisation: able to manage competing demands at pace, set clear expectations with stakeholders, and keep multiple workstreams on track simultaneously.
• Leadership trajectory: a track record of mentoring peers or junior colleagues, paired with a clear ambition to step into an Account Director role.
• Strategic curiosity: actively seeks to understand the broader business context — not just the channel — and uses that knowledge to shape more effective, integrated recommendations.
• Attention to detail: high standards across data accuracy and written and verbal communication.
• Collaborative: works closely with our strategy, research and data teams to build campaigns that solve real business challenges.

Key responsibilities:

• Strategic planning and execution: own the clients digital plans across the funnel, bringing a senior perspective to channel investment decisions and funnel architecture, with programmatic at the core and paid social as part of the mix.
• Senior client relationship: serve as the primary point of trust for the client on all activation matters, proactively anticipating needs and elevating the conversation beyond day-to-day delivery.
• Full-funnel campaign operations: connect channel-level execution back to the clients commercial KPIs, calling out what’s working and what isn’t.
• Quality and innovation leadership: set the standard for campaign quality, champion a culture of test-and-learn, and ensure financial reconciliations are consistently accurate and on time.
