We are part of IDHL, one of the UK’s largest digital marketing agencies. Together, we partner with an enviable roster of international clients.

Your role as Social Media Manager 

You’ll manage the social presence of our client partners — overseeing content, community engagement, and strategic delivery in collaboration with the wider social and paid teams.

Main Accountabilities

You’ll play a key role in shaping and activating bold social media strategies that elevate our clients’ brands. Working closely with the social team, you’ll ensure every campaign delivers exceptional creative and measurable impact — always looking for new ways to push the boundaries of what great social looks like.

You’ll develop strategies that drive awareness, engagement, and growth, and regularly analyse performance to make informed recommendations to senior stakeholders. Collaboration is at the heart of this role: you’ll work hand-in-hand with creatives, strategists, and other departments to ensure our work is cohesive, effective, and truly integrated.

As a trusted partner to our clients, you’ll build strong relationships across multiple industries, overseeing content development, approvals, scheduling, and community management. You’ll combine creativity and data to craft compelling campaigns, keep on top of trends, and turn insights into standout social moments that connect with audiences.

You’ll be an advocate for social excellence across the agency — sharing ideas, contributing to proposals, and helping teams across disciplines bring client goals to life. You’ll measure success through clear KPIs and ROI reporting, while keeping an eye on budgets to ensure projects are delivered efficiently and profitably.

Finally, you’ll continue to grow your expertise, representing the agency with professionalism at all times and supporting events or initiatives that showcase our work and culture.
