• Build advanced GTM and sGTM templates (clients, tags, variables), including sandboxed JavaScript logic, permissions, and data transformations.
• Design event ingestion workflows, transformation layers, and commerce analytics mappings (GA4 eCommerce, Measurement Protocol, etc.).
• Implement and optimize server‑side data routing, caching, and identity management.
• Integrate with external APIs (GA4, Ads, third‑party vendors) to support complex tracking setups.
• Lead complex technical initiatives that span across product and infra boundaries.

You Bring

• 5+ years of engineering experience, ideally with strong backend exposure.
• Deep hands‑on expertise with GTM and sGTM, including: Client templates, Tag templates, Variable templates, Permissions & sandboxed script restrictions.
• Strong proficiency in JavaScript, Node.js, and TypeScript.
• Solid grounding in API/service design & security.
• Strong understanding of GA4, e‑commerce schemas, Measurement Protocol, and cross‑platform data mapping.
• Experience with CDNs (e.g. Cloudflare, Akamai, GCP) for caching, edge execution, and traffic routing.
• Hands‑on experience with cloud‑native infrastructure (GCP is a plus).
• Ability to lead system design discussions and influence architectural direction.

Nice to Have

• Experience running Kubernetes clusters and container‑based tagging pipelines.
• Background from web analytics, digital measurement, or marketing engineering.
• Understanding of consent management, privacy enforcement, and compliance‑aware data flows.
• Experience integrating with Meta, TikTok, or other ads platforms.
