Commercial Analytics Engineer (4-6 months contract)

• Contract (4–6 months, duration negotiable)

• Option to convert to a full-time role by mutual agreement.

You will own the data platform that powers ZOE's commercial decision-making:

• Own how we design high-quality website data layers, feed clean conversion signals into ad platforms, and inform our experimentation on top of that data.

• Design and manage the GTM/sGTM containers and marketing platform conversion signals to ensure the resulting warehouse data quality powers experimentation and bidding decisions.

• Join a team that prizes high technical velocity and sits between marketing, engineering, and data. We use short feedback loops to keep our tracking accurate and our experiments trustworthy.

This is a hands-on build role. We expect you to write JavaScript, deploy infrastructure, define the data model, and wire it into BigQuery. Not just spec it for someone else.

💻 Our cutting-edge stack - a taste of what you'll use!

• Data & Infrastructure: GCP (Cloud Run / Docker), BigQuery, dbt, Dagster

• Tracking & Experimentation: GTM / sGTM (Server-side), Optimizely

• Marketing Platform Tools: Meta CAPI, Google Enhanced Conversions, TikTok Events API

• Tools & CI/CD: Braze, Mixpanel, Terraform, GitHub Action, HEX

We move fast, and this 4–6 month contract (duration negotiable), is designed for an architect who wants to build several high-stakes wins from the ground up. At the end of this engagement, there is an option to move to a permanent role by mutual agreement. Success looks like:

• Server-side GTM running in production with MetaCAPI / Google Enhanced Conversions / Mixpanel Server-side ensuring data accuracy and reliability.

• A governed event / data-layer spec used consistently across the web and ad platforms, driving informed decisions for our experimentation pipeline and marketing initiatives.

• Clear documentation and strategy on the infrastructure that’s built so others can build on top of it.

• Full-stack Google Tag Manager ownership: Strategy, governance, deployment and auditing tag configurations across both client-side ****and server-side GTM web containers.

• Robust event tracking & data layer quality: Own the direction and partner with front-end engineers to ship custom events that inform onsite experimentation, user journeys and analytical models.

• High-quality data pipelines for Marketing platforms: Build, maintain and improve data pipelines that send signals to Meta, Google, AppsFlyer and other platforms, troubleshooting discrepancies and ensuring data consistency across the marketing stack.

• Data platform for commercial: Build, maintain and improve the end-to-end ELT pipeline within BigQuery and dbt, from raw event ingestion through to analyst-ready data models.

• Privacy & consent: Manage the CMP integration with GTM Consent Mode; ensure no tags fire pre-consent and no PII leaks downstream.

Must-haves

• Production experience with GTM and sGTM, including data layer design, event schema implementation, writing custom GTM templates and sGTM client / transform logic.

• Strong JavaScript skills writing custom GTM tags and templates, implementing client-side event schemas, and debugging tracking instrumentation in the browser.

• Experience integrating conversion and value signals with advertising and attribution tools such as MetaCAPI / Google Enhanced Conversions / server-side event APIs in production.

• Proven experience with dbt and analytics-engineering practices to build best-in-class data models.

• Experience in creating a website data layer that informs marketing, commercial and product teams.

• Working knowledge of cookie consent management (e.g. OneTrust) and familiarity with multi-region / GDPR + CCPA.

Nice-to-have

• Experience with Mixpanel, Optimizely and/or Braze.

• Healthcare, D2C subscription, or other regulated-industry experience.

• Website experimentation literacy and what makes an A/B readout trustworthy.
