Role Summary

We're seeking a Google Tag Manager (GTM) Specialist to support the Digital Workplace Function, partnering with the Email and Microsoft Office product teams within Collaboration & Communication Services (C&CS). You'll own event tracking strategy, tagging, and data-layer quality to power reliable analytics and performance insights for internal digital services. You'll collaborate with a Senior Performance Analyst and a multidisciplinary team.

What you'll do

  • Own GTM implementation (web/app): plan, configure, and maintain tags, triggers, variables, and templates for robust, low-latency tracking.

  • Data layer & taxonomy: define/extend a scalable event schema and data-layer spec; document naming conventions and governance.

  • Consent & privacy: implement Consent Mode v2, CMP integrations, and tagging that respects privacy, security, and accessibility standards.

  • Server Side tagging (sGTM): design and/or maintain Server Side containers to improve data quality and control.

  • GA4 & BigQuery: ensure high-fidelity event collection, parameters, and user properties; validate exports to BigQuery for downstream analysis.

  • Debugging & QA: use Preview/Debugger, tag audits, and monitoring to detect regressions; create automated checks where feasible.

  • Stakeholder enablement: translate business questions into trackable events and KPIs; create clear implementation guides and runbooks.

  • Reporting enablement: collaborate on Looker Studio/Power BI dashboards by ensuring clean, trustworthy tracking inputs.

  • Performance & reliability: minimise tag bloat, resolve conflicts, and optimise loading strategies.

  • Change management: manage releases via versioning, environments, and rollback plans; integrate with agile delivery.

Essential skills & experience

  • 4-6+ years in GTM/GTM Server Side and GA4 implementation (web and/or app).

  • Strong data layer design, event modelling, and taxonomy governance.

  • Hands-on with Consent Mode v2, CMP integrations, PII controls, and privacy-by-design.

  • Comfortable with BigQuery (schemas, QA, basic SQL for validation).

  • Proficient in Looker Studio (for validation/health views; storytelling a plus).

  • Solid debugging across environments; familiarity with browser dev tools & network requests.

  • Clear communicator; can turn business needs into measurable tracking plans.

  • Experience working in agile, with version control and change management for tags.

Desirable

  • Server Side GTM in production (GA4, Ads, custom endpoints).

  • Power BI and/or Azure Data Services exposure.

  • Public-sector or large-scale internal service experience.

  • Basic JavaScript/TypeScript for custom templates and tag logic.

  • Understanding of accessibility implications for tagging and measurement.

Compliance & standards

  • Adheres to digital service standards, accessibility principles, and data governance.

  • Ensures tagging does not degrade user experience or expose sensitive data.
