The opportunity

You are a reliable driver of client work, with a developing strategic mindset. You own and run projects independently, leading defined multiple workstreams, transitioning from delivering projects to managing them alongside peers. You align stakeholders, shape clear decision paths, and keep scope, schedule, and quality in balance, connecting great work with commercial performance.

What you’ll be doing

• Manage multiple client projects, making decisions about approach, investment, and who we involve
• Develop and present recommendations to clients, shaping what we propose rather than just executing someone else’s plan
• Identify where clients need more from us and bring growth opportunities to the business with a clear case for investment
• Run project delivery with rigour on scope, timeline, budget, and margins, managing through complexity and ambiguity
• Mentor and guide team members on your workstreams, setting standards and building their capability
• Work with senior team members to stress test thinking and refine your approach on bigger or newer challenges
• Lead cross‑discipline partners to deliver at pace and quality, taking responsibility for outcomes
• Anticipate client needs and navigate conversations proactively so we stay ahead of problems
• Proactively meet with discipline leads to understand new approaches, ways of working or offers to integrate and support this growth
• You ensure the work is underpinned by the Thinking & Making philosophy and introduces elements of the Three Lenses
• Manage outcomes and pressures thoughtfully for you and the team, by staying pragmatic and positive

What we’re looking for

Experience – Track record of running multiple projects with strong commercial outcomes.

You connect what’s happening in their world to opportunities for us to do meaningful work whether that’s within our agency or the broader Omnicom world.

You weigh complexity, investment, and return, and you’re confident making the case internally, knowing how to influence and negotiate.Communication – You present with clarity and confidence. You articulate strategic thinking in ways that move people to action and decision because you also chair and facilitate the decision‑making process.
