Ad Tech & Data Manager

If you love turning complex ad tech ecosystems into elegant, scalable solutions — and you get a buzz from building foundations that power smarter marketing — this role has your name on it.

We’re looking for an Ad Tech & Data Manager to lead Ad Technology and Audience Strategy across a diverse portfolio of global clients spanning luxury, hospitality, travel, and FMCG sectors. You’ll sit at the intersection of technology, data, and activation, helping teams unlock performance today while building future-proofed capabilities for tomorrow. This is a hands-on, delivery-focused role for someone who enjoys owning the detail and the bigger picture — from platform setup and governance to audience strategy and roadmap leadership.

Owning the Ad Tech foundation

• You’ll take the lead on ad tech strategy and operations, ensuring platforms, tagging, identity, and verification are robust, consistent, and ready to scale across markets and channels.
• Own and evolve the ad tech roadmap, prioritising initiatives that unlock performance, efficiency, and governance.
• Translate ambiguity into clear plans — defining workstreams, timelines, owners, risks, and trade-offs.
• Build and maintain tagging and asset inventories, with strong QA and documentation standards.
• Set and govern verification standards, from partner setup to ongoing benchmarking.
• Support DSP and ad tech consolidation programmes.
• Oversee correct setup and governance across ad servers, DSPs, and social platforms.
• Lead vendor assessments, pilots, and rollouts, creating enablement materials that drive adoption.
• Develop playbooks, run training sessions, and empower activation teams with repeatable best practice.

Driving smarter data and audience activation

• You’ll help teams move beyond one-off targeting to scalable, reusable audience strategies by:
• Defining clear audience management standards, including taxonomy and segmentation principles.
• Providing guidance on the use of 1st, 2nd, and 3rd-party data across platforms and use cases.
• Supporting teams to build, activate, and optimise audience segments in-platform.
• Contributing to CDP and first-party data activation workstreams.

What you’ll bring

• You’re confident navigating the digital advertising ecosystem and understand how the pieces fit together.
• Strong knowledge of ad servers, DSPs, search, identity, and measurement platforms.
• Hands-on experience with ad serving or activation platforms, ideally within Google Marketing Platform (e.g. CM360, DV360).
• Solid experience with tagging, tracking QA, and data quality governance.
• Proven project management skills across multiple workstreams and senior stakeholders.
• The ability to clearly communicate recommendations and progress through decks, docs, and working sessions.
• Confidence producing runbooks, governance frameworks, and stakeholder-ready updates.
• Familiarity with identity and privacy-safe data activation solutions.
• Experience working across multiple markets or within global-local operating models.

If you’re excited by the idea of leading ad tech and data strategy, partnering with brilliant teams, and shaping how modern marketing works — we’d love to hear from you. Apply now and let’s start the conversation.
