Associate/Manager, Zapp Media Services (Retail Media)

Vauxhall, London.

About Zapp

Zapp is London's leading premium convenience retail platform. Founded in 2020, our vision is to disrupt the multi-trillion dollar convenience retail market, currently dominated by major players, by developing best-in-class customer-centric technology and fulfilment solutions. Zapp partners with some of the world's leading brands to deliver an exclusive range of hand-picked products 24/7, delivered in minutes.

Job Summary

Zapp Media Services (ZMS) is Zapp's retail media business. We help premium brands reach London's most valuable grocery customers through in-app media, CRM, sampling, packaging, out-of-home and experiential activations, and we prove what that investment delivered.

Our Category Managers own each brand relationship and lead the Joint Business Plan (JBP). You will sit alongside them as the ZMS specialist: you shape the media section of the JBP, agree objectives and measures up front, then run every activation from brief to go-live to results. You will report performance back to brands, and to our senior leadership, in a way that earns the next, bigger plan. The brands we work with expect the quality of a global agency at the speed of a startup.

At this level, success is defined by flawless delivery: every booked activation lands on time, looks premium and is measured properly, and every brand leaves a campaign wanting to rebook. You will also help build ZMS as a function, turning what you learn on each campaign into better packages, processes and tools.

Key Responsibilities and Expectations

Shape the plan

• Join Category Managers in JBP conversations with brand partners and build the ZMS section of each plan: objectives, media mix, timings, investment and the measures we will report against.

• Build proposals from Zapp's rate card and media inventory, matching each activation to the brand's goal, whether that is trial, penetration, a new product launch or a seasonal sales moment.

• Turn brand briefs into clear internal briefs for Marketing, CRM, Creative, Supply Chain and Category teams, each with an owner and a deadline.
  

Deliver the activations

• Own end-to-end delivery of every campaign in your portfolio across multiple channels: in-app placements and sponsored listings, homepage and category takeovers, push and email CRM, sampling and gift-with-purchase, bag drops and inserts, social, experiential and out-of-home.

• Run the campaign calendar and media inventory so we never double-sell a placement, miss a go-live date or run a campaign without stock behind it.

• Work across Marketing, Supply Chain, Product, Legal, Finance and Operations to land each campaign seamlessly, including getting sampling and gift-with-purchase stock to the right fulfilment centres on time with clear picking instructions.

• Check every activation live in the app and on justzapp.com before confirming launch to the brand, and fix issues the same day.

• Manage creative and asset approvals with brands and their agencies, holding the line on Zapp's brand standards.
  

Prove the results

• Deliver post-campaign reports within agreed timelines, covering delivery (impressions, clicks, samples distributed), sales uplift, new-to-brand customers and repeat rate against the objectives set in the JBP.

• Pull your own data from Claude, and turn it into a clear story with a recommendation for the next campaign.

• Present campaign results and insights to brand partners and to Zapp's senior leadership.

• Keep a live campaign tracker so Category Managers, Finance and leadership can see what is booked, live, delivered and invoiced at any time.

• Raise the billing paperwork for each campaign with Finance, so every pound committed is invoiced and collected.
  
  Build ZMS

• Establish and document best practice for campaign delivery, so every brand gets the same standard whoever runs their campaign.

• Capture what worked and what did not after each campaign, and turn repeatable wins into standard packages on the rate card.

• Spot upsell opportunities in campaign results and hand them to the Category Manager with the data to support the conversation.

• Stay ahead of retail media and premium brand trends, and bring new activation ideas that keep ZMS ahead of the market.
  

Core Competencies and Skills

• 2–5 years in retail media, trade or shopper marketing, media agency account management, or partnerships at a retailer, marketplace or FMCG brand. At Manager (L5) level, you have run multi-channel brand campaigns on your own from brief to results.

• Proven experience executing marketing campaigns and improving their performance using data.

• Highly organised: you run many campaigns at once, each with different stakeholders and deadlines, and nothing slips.

• Data driven: confident in Excel, Google Sheets and AI tools, and able to turn campaign results into a clear, honest story.

• Builds strong relationships with brand partners and internal teams, and presents insights to senior audiences with confidence.

• High standards for detail and presentation: you notice the wrong pack shot before the brand does.

• Proactive, entrepreneurial and hands-on, willing to roll your sleeves up and seek solutions in a fast-paced environment.

• Experience with retail media platforms, sponsored listings or programmatic advertising.

• Experience delivering sampling, experiential or out-of-home campaigns with physical logistics behind them.

• Knowledge of premium food and drink, health and beauty, or household brands, and the UK grocery landscape.
