Measurement And Implementation Manager

Description:

Measurement and Implementation Manager owns the technical measurement architecture for ATG web and native app platforms. You will design and govern the data layer, implement GA4 event schemas and ecommerce tracking, run server-side Google Tag Manager deployments, and maintain app tracking and mobile attribution integrations. Your work makes sure reliable data reaches analytics, BigQuery and the ad platforms, so product, commercial and marketing teams work from numbers they trust.

This role brings work currently delivered by an external agency in-house. You will lead that handover, document what has not been documented before, and become the internal technical owner of the measurement stack. The remit of the team is expanding from insight generation to owning the measurement platform end to end, and this role sits at the centre of it.

You will be the main technical partner to Product, Engineering, Marketing and external vendors, accountable for measurement governance, tracking for new product releases and territory launches, data quality monitoring, and consent-aware measurement. Day to day you will run QA and anomaly detection, resolve discrepancies across GA4, mobile attribution and the ad platforms, and put monitoring in place so tracking failures surface in days rather than months.

We are looking for a pragmatic, hands-on measurement engineer. You pair technical execution with clear communication, explaining tracking problems to people who do not work in analytics, and you keep the tracking architecture current as privacy rules and platforms change.

This is a permanent, full-time role with hybrid working.
