About One Day Agency

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 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.

Office Manager

📍 Manchester, office-based, Monday-Thursday

Flexible working schedule | Full-time and part-time arrangements considered

About One Day

One Day is an integrated advertising and marketing agency built around one collaborative team. We work across creative, media and digital for ambitious brands in the UK and around the world, without unnecessary departments or barriers. Our day-to-day environment is informal, supportive and fast-paced, but we care deeply about professionalism and delivering brilliant work.

The Role

We’re looking for a brilliant organiser to take ownership of the day-to-day running of our Manchester office. You’ll create a welcoming, well-organised environment for our team and visitors while keeping the practical details moving behind the scenes. This is a hands-on role at the heart of the agency. You’ll be the person who notices what is needed, solves problems early and makes it easier for everyone else to do their best work.

Key Responsibilities

Office and Workplace Operations

• Act as the first point of contact for the Manchester office, welcoming visitors and helping the team with day-to-day office needs.

• Manage the main office phone and shared inbox, responding promptly and directing enquiries to the right person.

• Keep the office well stocked and ready for the week, including stationery, kitchen supplies, food, drinks and snacks.

• Coordinate third-party suppliers, including cleaners, maintenance teams, building management, couriers and other workplace partners.

• Manage meeting rooms, deliveries, office access, equipment and practical arrangements for client and team meetings.

• Identify problems before they become distractions and take ownership of getting them resolved.

Administration and Project Support

• Track routine office spending against agreed budgets and help the team make sensible, cost-conscious purchasing decisions.

• Support the practical side of staff onboarding and off-boarding, including office access, workspace set-up and essential information.

• Provide reliable ad hoc administrative support to the leadership and operations teams when needed.

Team and Client Experience

• Organise team socials, lunches, celebrations, off-sites and other moments that bring people together.

• Coordinate thoughtful staff and client gifts for birthdays, milestones, campaign launches and special occasions.

• Help meetings and agency events run smoothly, including room preparation, catering, refreshments and guest logistics.

• Suggest and introduce ideas that make the office more welcoming, efficient and enjoyable for everyone.

What We’re Looking For

• Previous experience in office management, office coordination, administration, team assistance, reception or a similar hands-on role.

• An exceptional organiser who can manage several priorities without losing attention to detail.

• A warm and confident communicator who is comfortable speaking with colleagues, clients and suppliers.

• A proactive and practical approach. You won’t wait to be told when something clearly needs attention.

• Reliability, good judgement and discretion when handling supplier information or sensitive internal details.

• Confidence using Google Workspace. Experience with invoice or accounting systems such as Xero would be helpful but is not essential.

• A genuine team player who enjoys helping people and takes pride in creating a brilliant place to work.

What Success Looks Like

• The office is consistently organised, stocked and ready for the team.

• Calls, inbox enquiries, visitors and supplier requests are handled quickly and professionally.

• Office and invoice administration is accurate, timely and easy for others to follow.

• Team events and thoughtful details are well planned and genuinely enjoyed.

• Your colleagues trust you to take ownership and get things done.

Salary and Benefits

💰 Competitive salary based on experience and the agreed working pattern.

📍A four-day working week, Monday to Thursday, based in our Manchester office. Full-time or part-time hours can be considered.

🌴 Up to 30 days of annual leave, pro rata for part-time employees.
