Job description

One Day Agency is an integrated advertising and marketing agency with offices in Manchester, London, Paris, and Warsaw.

In just seven years, we’ve built a team of 20 specialists delivering campaigns for brands of all sizes across the globe, from fast-growing e-commerce brands to Formula 1 teams. We specialise in strategic media planning and buying across OOH, TV, Radio, Digital and wider ATL channels, helping brands grow through smart, commercially focused advertising. Our model is different from traditional agencies. We work fast, stay hands-on, and give people real ownership early.

The Role

We’re looking for a Senior Growth Manager to join our fast-paced Growth Team.

This is not a traditional siloed agency role. You’ll be involved across strategy, pitching, media planning, buying, client management, campaign delivery, and commercial growth, working directly with both clients and media partners across UK and international markets.

You’ll take ownership of projects from brief through to delivery, managing multiple campaigns and priorities at once across OOH, TV, Radio, Digital and wider ATL media channels. This role is ideal for someone who enjoys variety, likes responsibility, and wants exposure to all areas of agency life rather than being confined to a narrow role.

Key Responsibilities

• Manage and convert inbound client opportunities (no cold calling)
• Build media plans and campaign recommendations across multiple channels
• Plan and buy media across OOH, TV, Radio and Digital channels globally
• Lead client communication and build strong long-term relationships
• Manage campaigns end-to-end from briefing through to execution
• Work directly with media owners and external partners
• Lead pitches, proposals and wider growth initiatives
• Collaborate closely with internal teams to deliver campaigns successfully

What We’re Looking For

• 3+ years experience within an agency or advertising sales environment
• Must have direct experience with planning and buying OOH campaigns
• Experience managing campaigns or clients end-to-end
• Strong organisation skills and ability to juggle multiple priorities
• Confident communicator comfortable dealing directly with clients and partners
• Commercial mindset with strong attention to detail
• Ability to work independently and take ownership
• Positive attitude, resilience, and willingness to learn quickly
• Interest in OOH, TV, Radio, Digital and wider media strategy

This role suits someone who thrives in fast-paced environments, enjoys problem solving, and wants to accelerate their learning and career progression.

Salary & Benefits

Salary: £37,000 to £45,000 base + uncapped commissions (+£50,000 potential, avg. £15,000 first year)

WFH every Friday + 20 additional WFH days per year.

Up to 30 days annual leave

Doctor Care Anywhere, access to GP and Advanced Clinical Practitioner appointments, available 24/7, 365 days a year.
