Job Description

GAIN is a creative-led, insight-driven company that blends data, tech and creativity. We believe the best ideas emerge where intelligence and creativity unite, where insight sparks imagination, and where innovation turns possibility into progress.

We are explorers of new frontiers, shaping bold strategies that move people, brands, and businesses forward. Individually and together, our specialist teams provide the vision, data, and confidence brands and organisations need to make braver, more impactful decisions.

Today as GAIN, we work as a united force, using data to fuel creativity, and technology to unlock new possibilities. As imagineers we don’t just embrace innovation – we engineer it, transforming information into action, and ideas into breakthroughs.

This is where rebel thinking, smart technology, and data-driven creativity shape the future.

Through our five specialist teams: Creative Studio, Conversion, Customer Science, Experience and Performance. Individually, and together, we work to fuel your growth, and deliver measurable impact.

THE ROLE:

As a Media Strategist / Media Planner, you will support the development and delivery of integrated media plans across traditional and offline channels for GAIN’s growing client accounts. Working closely with senior account leads, planning teams and media specialists, you will help shape media recommendations that balance brand awareness, audience reach and commercial performance.

You will contribute to the planning, coordination and optimisation of campaigns across channels such as TV, radio, print, out-of-home (OOH), cinema and audio, while also collaborating with digital and performance teams where required. This role is designed for a developing media professional looking to build strong planning fundamentals, commercial awareness and cross-channel understanding within a fast-paced agency environment.

You will play an important role in campaign planning, audience analysis, reporting and day-to-day client servicing, ensuring media activity is well organised, insight-led and aligned to client objectives.

THE TEAM:

GAIN Media Strategy is a small team today. We are built from Customer Science strategists by trade, with 10+ years each running client relationships at agencies, effectively acting as the agency-side CMO for the brands we look after. We know audiences, planning and how to land work with senior clients. What we want to enhance now is our media proposition that we can scale, properly grounded in customer understanding rather than channel habit.

That means this isn’t a role where you slot into a big media machine and follow the process. There is no defined machine yet albeit a strong foundation of pre-existing media client retainers & project work. There is a real client book, two experienced strategists, the wider weight of GAIN behind us, and a genuine opportunity to help shape what “media at GAIN” looks like.

If you’re after an easy ride inside a big network agency, this won’t be it. If you want to build something, this is unusually fertile ground.

WHAT WE’RE LOOKING FOR:
Amid-weight media strategist or planner who’s entrepreneurial by instinct, proactive by default, and who actively wants to be challenged, and to challenge us back. We don’t want a yes-person; we want someone who’ll push our thinking, bring fresh industry perspective, and help us make the most of what we already have while we build.

You’ll likely have around three to five years in a media agency or planning role, with strong fundamentals across traditional and offline channels. More important than the years is the mindset: comfortable with ambiguity, hungry to learn, willing to own things, and confident enough to say “I think we should approach this differently” when you mean it.
