Overview

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.

Why this role?

This is a chance to play a pivotal role in shaping how world-class brands across luxury, hospitality, travel, and FMCG activate data and technology at scale. You'll have real ownership, real influence, and the opportunity to build systems and standards that make a lasting impact.

Responsibilities

What you'll be doing

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. You'll:

• 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

Qualifications

What you'll bring

You're confident navigating the digital advertising ecosystem and understand how the pieces fit together. You likely have:

• 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

Ready to build what's next?
