About the role:

This is a senior campaign management role sitting at the intersection of client partnership, media strategy, and performance delivery. You'll own the campaign calendar, manage media budgets across channels, coordinate media buying partners, and report on outcomes to senior stakeholders — all while maintaining the rigour and responsiveness that a high‐volume, always‐on media environment demands.

Success in this role looks like campaigns that consistently hit or exceed KPIs, a client that feels well‐informed and strategically supported, and a clear, data‐driven improvement in ROAS, traffic, and brand performance over time.

What you will be doing:

• Client Management: Act as the key liaison between the client's UK office, HQ, and agencies—ensuring seamless communication and strategic alignment across all campaign activity. Lead regular client meetings to review campaign goals, performance data, and feedback—presenting clearly and confidently to senior stakeholders. Provide timely reports on campaign progress and budget utilisation, making complex data accessible and actionable. Build long‐term client relationships and proactively identify new opportunities to deliver value.
• Market and Audience Analysis: Analyse target audience behaviour and media consumption patterns to inform channel and messaging strategy. Conduct competitor and category trend research to keep campaigns sharp and contextually relevant. Leverage tools including Google Analytics, Magento, and other data platforms to generate actionable insight.
• Media Strategy Development: Develop media strategies that balance brand awareness objectives with conversion and e‐commerce performance goals. Recommend optimal channel mixes and campaign timing based on business objectives and audience insight. Integrate market, consumer, and platform trends into strategic proposals— with a strong working knowledge of the UK media landscape.
• Budget Allocation and Optimisation: Manage media budgets across channels, allocating spend efficiently against reach, frequency, engagement and conversion objectives. Adjust allocations in response to live performance data, with clear data‐backed rationale for every budget decision. Oversee daily, weekly and monthly budget tracking—providing clients with detailed cost breakdowns and managing discrepancies through prompt, clear communication. Manage invoicing and payment processes with external vendors, ensuring financial accuracy throughout.
• Media Buying Coordination: Collaborate with internal teams and media buying partners to ensure campaigns are briefed clearly and executed to specification. Communicate briefs that include targets, KPIs, naming conventions, and deadlines—and provide execution guidelines that enable alignment and efficiency across all partners.
• Campaign Execution and Performance Optimisation: Manage and monitor campaigns across Google Ads (YouTube, PMax, GDN, Shopping, Demand Gen), Meta, Programmatic, SA360, Retail Media, GA, CM360 and other relevant platforms. Monitor real‐time performance daily and adjust targeting, bidding, creative and channel strategies as needed. Analyse creative formats, keyword performance and audience targeting to drive continuous optimisation across all active campaigns. Coordinate with designers, media partners and platform contacts to ensure flawless execution at every stage.
• Reporting and Insights: Deliver detailed performance reports covering impressions, clicks, conversions, ROAS and other relevant KPIs. Use performance data to refine live strategies and inform future planning cycles. Lead post‐campaign reviews that generate clear learnings and concrete optimisation recommendations.
• Cross‐Team Collaboration: Coordinate across creative, production, data and platform teams to keep internal delivery aligned with client expectations and campaign timelines. Ensure internal schedules, priorities and outputs remain in step with campaign requirements at all times.

What you need to be great in this role:

• Proven experience planning and executing end‐to‐end paid media campaigns across digital channels— including Google Ads, Meta, Programmatic, SA360, Retail Media and CM360.
• Track record of managing D2C media campaigns for brand‐owned online stores, with measurable improvements in ROAS, traffic and conversion performance.
• Strong understanding of the UK media landscape and how to apply audience and competitor insight to media strategy.
• Experience acting as a senior client liaison—managing expectations, leading performance reviews, and presenting to senior stakeholders with clarity and confidence.
• Demonstrated ability to build long‐term client relationships and identify strategic opportunities beyond the immediate brief.
• Proficiency with Google Analytics, Magento and data visualisation tools—able to combine multiple data sources into clear, decision‐ready insight.
• Strong working knowledge of Excel and data visualisation for budget tracking, performance reporting and variance analysis.
• Ability to translate complex performance data into straightforward strategic recommendations.
• Experience managing multi‐channel media budgets, including allocation decisions, real‐time optimisation, variance forecasting and detailed spend reporting to clients.
• Confident handling of vendor invoicing and payment processes with accuracy and clear communication.
• Demonstrated ability to manage multiple concurrent campaigns and workstreams—balancing competing priorities, timelines and stakeholder requirements without losing quality or detail.
• Experience working across cross‐functional teams including creative, production, analytics and agency partners.
• Professional proficiency in English is required; professional proficiency in Korean is an advantage.
• Advanced use of Gen AI tools relevant to campaign management and media planning—including tools that support insight generation, performance analysis, reporting automation, brief writing and workflow optimisation.
• Experience building personal AI‐assisted workflows that improve efficiency and the quality of campaign reporting and analysis.
• Ability to guide others on responsible and effective use of AI tools within a campaign and media context.
• Agentic approach to complex, multi‐platform campaign challenges—breaking problems down systematically, identifying the most efficient path to resolution, and executing with consistency.
• Rigorous human oversight of AI‐generated outputs—validating analysis and recommendations before sharing with clients or acting on them.
• Experience in consumer electronics, technology or retail media environments.
• Familiarity with Magento or equivalent e‐commerce platforms.
