Ad Tech Consultant- Senior Manager in London

The purpose of this role is data analysis/guided deliverable development in support of assessment/strategic deliverables.

About Merkle & Dentsu

Merkle is a leading data-driven customer experience management (CXM) company that specialises in delivering unique, personalised customer experiences across platforms and devices. With a 30-year heritage as a data and analytics consultancy, Merkle became part of Dentsu in 2016—one of the world’s top five agency networks, with 60,000+ employees across 146 countries. Dentsu leads the region in digital media trading. We generate more data, drive more audience engagement, and track everything. We specialise in applying technology to deliver unmatched ROI for our clients. As a result, we take a laser-focused approach to implementing and integrating technology across our digital business.

The Role

Every year, a larger share of advertising and marketing is bought digitally, and companies are turning to advanced technologies to maximise their budgets. However, implementing adtech and martech is complex, challenging, and ever-changing—which is why specialist knowledge is essential to ensure it’s done correctly. Google Marketing Platform (GMP) is among the world’s most advanced platforms for buying, managing, and measuring digital advertising. Merkle is one of a select group of companies entrusted by Google to help global businesses set up their technologies the right way.

As an Ad-Tech Consultant, you will lead projects advising some of the world’s biggest companies on how to architect and implement advertising and marketing technologies—including GMP—to deliver best-in-class digital communications. You will also help companies measure the impact of their media activity using Google and other tracking technologies. Initially, the role will focus on consultancy services around Paid Search, notably SA360 and Google Ads, but will increasingly span multiple platforms. No two client engagements are the same, making this an exciting opportunity for a candidate looking to leverage their paid media expertise while gaining exposure to broader platforms, data, adtech, and martech.

Life as an Ad-Tech Consultant at Merkle

You will report to the Ad Tech Consulting Director, working across a portfolio of retained clients and project work.

Key responsibilities include:

• Leading client relationships across technology partner operations, assisting businesses with GMP implementation (notably SA360) and features to drive results.
• Conducting discovery sessions with clients to deeply understand their businesses and translate complex needs into clear technology requirements.
• Advising clients on how their advertising and marketing technologies should be set up and integrated.
• Training clients, their teams, and agency partners on the architecture and best practices you’ve defined.
• Contributing to consultancy projects, including auditing advertising technologies and creating recommendations to enhance tool and platform usage.
• Collaborating with vendor technology teams to co-deliver architecture projects and proactively suggest and test product improvements.

What You Will Bring to the Team

• 5+ years of experience in digital marketing, advertising, and/or analytics.
• Strong knowledge of the Google Marketing Platform stack, especially SA360. Experience with DV360, CM360, or Paid Social platforms (Meta, Snap Ads) is an advantage.
• Solid understanding of measurement technologies related to GMP (GA4, Floodlight, Enhanced Conversions, Consent Mode) and how conversion measurement impacts paid media optimisation.
• Expertise in performance optimisation strategies and platform features (particularly SA360).
• Significant experience working directly with clients and/or internal stakeholders, including leading meetings and presentations.
• Familiarity with platform integrations, data flows, and campaign taxonomies.
• Understanding of how to utilise client first-party data to optimise marketing activity within GMP.

A few of the benefits

• You’ll have a great compensation package, private health & dental insurance, corporate discounts and career development through Dentsu University, and free access to LinkedIn learning.
• 29+ days of annual leave (25 days of regular holidays, birthdays off and 3 additional wellness days).
• We also offer the opportunity to volunteer for up to 2 days per year and tend to close down the agency between Christmas and New Years.
• You’ll have a hybrid working schedule, with flexible start/end hours.
