You'll be joining the Digital Media team. We are a vibrant, data-driven function collaborating closely with creative, data science, and marketing technology teams to deliver innovative campaigns.

Here's what your day-to-day might look like:

• Manage end-to-end platform setup, activation, optimisation, and reporting for programmatic video and paid social across brand proposition and tactical campaigns.

• Respond to briefs in collaboration with internal planning teams, forecasting audience reach and recommending channel strategies to meet commercial goals.

• Build and manage ad-serving tags, trackers, and CM360 trafficking processes to ensure accurate performance measurement and conversion tracking.

• Design and run A/B tests and brand lift studies to strengthen channel insights and systematically improve campaign efficiency.

• Deliver weekly performance updates and post-campaign analysis, translating complex metrics into actionable learnings for key internal and external stakeholders.

Our ideal candidate will bring strong expertise in some of these areas and curiosity to grow in others:

• Direct expertise activating and optimising media via DV360, Meta, and Tik Tok within a high-growth consumer-facing or D2C brand.

• Strong knowledge of the display and video media ecosystem, including hands-on experience with CM360 trafficking and conversion tracking tools.

• Proven quantitative and analytical skills with demonstrated ability to synthesise complex data into actionable insights and structured reports.

• Excellent stakeholder management skills with a track record of building trust across internal teams, platform representatives, and external agencies.

• A self-starter mindset with strong problem-solving capabilities and the ability to adapt quickly in a fast-paced environment.
