Sr. Engineer - Martech (Data Capture)

You will own the measurement and data capture layer across Redbubble and TeePublic. That means server-side tagging, pixel infrastructure, CDP event pipelines, and the consent and governance layer that sits under all of it. You will work closely with marketing, product, and the data engineering team to ensure events are accurate, governed, and activated reliably. This is a hands-on IC role. You will not just maintain existing infrastructure. You will design it, document it, and set the bar for how data flows from user action to platform.
The core responsibilities for the job include the following:
Server-side tagging and pixel infrastructure:
Own server-side GTM configuration across both brands, including container setup, tag templates, and routing logic
Maintain and extend client-side and server-side pixel implementations for Google, Meta, and other ad platforms
Manage tag governance: naming conventions, versioning, deprecation, and audit trails
Debug measurement gaps and signal loss across funnel
CDP event pipelines:
Build and maintain RudderStack source configurations, transformations, and destination routing.
Own the event schema: instrumentation specs, validation rules, and data dictionary.
Triage and resolve event quality issues across web, app, and backend sources.
Support consent management integration with the tagging layer (OneTrust or equivalent).
Third-party data ingestion:
Build and maintain ingestion pipelines using Funnel.io, Fivetran, or equivalent tools for external marketing datasets (spend data, platform reporting, and offline data).
Ensure ingested data land in the warehouse with a consistent schema, provenance tagging, and refresh cadence documentation.
Measurement and reporting support:
Support campaign attribution and funnel reporting by ensuring upstream data quality.
Partner with analytics on event taxonomy and metric definitions.
Requirements:
5-7 years in measurement engineering, MarTech data capture, or a closely related role.
Hands-on server-side GTM: container management, custom tag templates, routing to downstream endpoints.
RudderStack or equivalent CDP: source config, transformations, destination management.
Strong understanding of consent signal handling and its effect on measurement (GDPR, CCPA).
SQL proficiency and Python for pipeline logic, transformations, and debugging.
Experience integrating third-party data via tools like Fivetran, Funnel.io, or direct APIs.
Preferred:
Experience with both Google and Meta pixels and Conversion API implementations.
Familiarity with identity resolution concepts and how they intersect with server-side measurement.
Exposure to Airflow or another orchestration tool for scheduling ingestion jobs in e-commerce or marketplace backends.
