Senior Account Manager – Brand & Packaging | London / Hybrid

The Opportunity

If you’re at your best when you’re close to your clients – understanding their business, spotting opportunities and becoming someone they genuinely trust – this could be a great next move.

We’re working with a leading global creative agency looking for a Senior Account Manager to join their Client Services team, working across a portfolio of well-known food and snacking brands.

You’ll take a leading role in developing client relationships and growing accounts, while helping turn commercial and brand challenges into brilliant creative work across branding & packaging, eCommerce and lifestyle photography.

It’s a great opportunity for someone who wants to be more than a day-to-day account handler – you’ll have the scope to influence the direction of your accounts, identify opportunities for growth and become a true extension of your clients’ teams.

The Role

As Senior Account Manager, you’ll be responsible for:

• Building and developing strong, long-term client relationships.
• Identifying opportunities to grow accounts across the agency’s wider capabilities.
• Taking ownership of revenue targets and supporting account growth.
• Leading client conversations, presentations and workshops.
• Understanding clients’ business and brand challenges and translating them into clear, actionable briefs.
• Partnering closely with Creative, Project Management and Resource teams.
• Ensuring projects are delivered on time, on budget and to a high standard.
• Overseeing project plans, status reports, cost estimates and trackers.
• Managing forecasting, invoicing and overall account financial performance.
• Supporting and mentoring junior members of the Client Services team.

About You

We’re looking for someone who has:

• 4–5+ years’ experience in Client Services or Account Management within a branding, packaging or design agency.
• A strong understanding of branding, packaging and the creative development process.
• Strong commercial awareness and a track record of developing and growing client relationships.
• Experience managing project finances, forecasting and budgets.
• Excellent communication, presentation and stakeholder management skills.
• The confidence to navigate challenging conversations and drive positive outcomes.
• Strong organisational and project management skills.
• A proactive, collaborative and solutions-focused approach.
• A genuine interest in consumer brands, FMCG, food or snacking categories.

If you’re a commercially minded Senior Account Manager who loves building strong client relationships, spotting opportunities and helping great creative work happen, we’d love to hear from you.
