Responsibilities

• Measurement architecture and implementation - Audit GA4 properties end to end — data streams, key events, custom dimensions and metrics, channel groupings, cross-domain configuration, internal and staging traffic exclusion, attribution settings and data retention. - Rebuild and configure GA4 to a documented standard, including e-commerce and enhanced measurement. - Own GTM web containers: audit, restructure, naming conventions and governance, trigger and variable design, and disciplined version control and publishing. - Design and implement server-side GTM — hosting via Stape, Addingwell or GCP, custom clients and tag transports, and phased migration from client-side without breaking data continuity. - Diagnose measurement failures: duplicate transactions, inflated user counts, misfiring tags, attribution gaps and cross-platform discrepancies, using live debugging, BigQuery and platform interfaces.
• Consent and compliance - Audit, configure and rebuild consent management platforms – OneTrust, Cookiebot, Civic and similar – including cookie catalogues, categorisation and blocking behaviour. - Implement and validate Google Consent Mode v2 across both client-side and server-side environments. - Manually audit hard-coded tags across client sites to confirm they genuinely respect consent. This is the work most audits skip, and it is where the real exposure sits. - Maintain cookie and tag registers, and support clients on PECR and UK GDPR obligations alongside their legal and compliance teams.
• Paid media measurement - Audit, build and validate conversion tracking and pixels across Google Ads, Meta, TikTok, LinkedIn, Microsoft Ads and affiliate platforms. - Implement enhanced conversions, Meta Conversions API, TikTok Events API and equivalent server-side event flows. - Resolve deduplication, event match quality and consent-driven signal loss so that automated bidding is working from data we trust. - Work directly with our paid media teams to translate measurement problems into campaign decisions, and vice versa.
• Data and CRM integration - Integrate Salesforce with Google Ads and GA4 for offline conversion import and closed-loop reporting. - Extend the same approach to Microsoft Ads, LinkedIn and other platforms using Zapier, native connectors or custom endpoints. - Configure and use BigQuery exports for validation, reconciliation and reporting.
• App measurement - Audit and implement app tracking across Firebase and GA4, including event taxonomy and parameter design. - Handle App Tracking Transparency and in-app consent, and audit SDK behaviour against the consent state. - Work with mobile measurement partners on attribution setup, SKAdNetwork and deduplication against web activity.
• Specification, QA and documentation - Write bespoke data layer specifications that development teams can build from without coming back with questions. - Run structured QA before and after every release, with a documented test plan rather than a spot check. - Produce audit reports and implementation documentation that clients keep and actually use. - Set and maintain the internal standards, templates and naming conventions the wider team works to.

Requirements

• Hands-on implementation experience with GA4 and Google Tag Manager, in an agency, consultancy or complex in-house environment.
• Demonstrable server-side tagging experience.
• Strong working knowledge of consent management and Consent Mode v2, and the confidence to audit tag behaviour manually rather than trusting a vendor dashboard.
• Conversion tracking experience across major ad platforms.
• Ability to write clear technical specifications a developer can build from.
• Able to own a project plan, hold a timeline and flag risk early.
• CRM-to-ad-platform integration, particularly Salesforce, and familiarity with tools like Zapier for the platforms without native connectors.
• App measurement: Firebase, GA4 for apps, and any of the major MMPs (Branch, AppsFlyer, Adjust).
• Experience running training sessions or workshops for non-technical audiences.
