Senior GTM/GA4 Analytics Specialist (Hourly Contract)

We are seeking a Senior GTM & GA4 Specialist to support advanced tracking implementations and product feed optimization across global paid media initiatives for one of our largest clients in the marketing industry.

This role requires hands-on technical expertise, strong troubleshooting capabilities, and the ability to work autonomously in complex performance marketing environments. Above all, we are looking for someone who owns tracking problems end-to-end: you dig into a discrepancy, chase it to root cause, and drive the fix to a trustworthy resolution rather than flagging it and moving on.

Key Responsibilities

• Google Tag Manager (Advanced Implementation)
• Own end-to-end GTM implementations across multiple accounts.
• Configure advanced event tracking, custom variables, and complex triggers.
• Diagnose and resolve tracking discrepancies independently, driving each one to closure rather than leaving it as a known issue.
• Ensure tracking consistency across paid media and analytics platforms.

Data Feed Strategy & Optimization

• Lead product feed optimization using DataFeedWatch or similar platforms.
• Develop advanced feed rules, segmentation logic, and performance-based optimizations.
• Partner with paid media teams to improve Shopping campaign performance through feed structure enhancements.
• Troubleshoot feed disapprovals, mismatches, and data inconsistencies, seeing each resolution through to the end.

Analytics & Validation

• Configure and validate GA4 tracking frameworks.
• Audit tracking setups proactively and surface gaps before they become client-facing problems.
• Support attribution accuracy and conversion tracking alignment.

We're looking for:

• 3+ years of hands-on experience implementing Google Tag Manager. (Required)
• Advanced experience configuring custom events and debugging GTM containers. (Required)
• 2+ years managing product feeds for Google Shopping campaigns.
• Experience using DataFeedWatch or equivalent feed management platform.
• Direct experience supporting paid search campaigns.
• Strong troubleshooting skills, with a methodical, hypothesis-driven approach to resolving tracking discrepancies.
• A proven track record of chasing hard technical problems to root cause and validating that a fix actually holds, not just goes quiet.
• The autonomy to operate in complex, multi-account environments without heavy direction.
• Experience working in a performance marketing agency environment.
• Clear, concise communication in English, including the ability to explain complex tracking and feed logic to non-technical stakeholders.
• Experience in eCommerce environments. (Advantage)
• Experience working with large-scale paid media accounts. (Advantage)
• Google Ads certification. (Advantage)
