GA4, GTM, JavaScript, HTML/CSS, Data Layer, DOM, Custom Events, Consent Management, APIs, JSON, CORS and browser debugging

Job Description

4–8 years of overall experience, with strong hands-on experience in web development and digital analytics implementation

This is not a GA4 reporting or GTM configuration-only role. The candidate should be comfortable working at the application-code level, including JavaScript development, dataLayer implementation, DOM/event handling, API integrations, browser/network debugging, CORS troubleshooting, consent management, and complex analytics implementations.

The candidate will work closely with development, eCommerce, marketing, analytics, QA, consent/privacy, and other MarTech teams.

Key Responsibilities

  • Design, develop, implement, and maintain GTM and GA4 tracking solutions across websites and digital platforms.
  • Design and develop scalable dataLayer implementations using JavaScript.
  • Implement GA4 events, parameters, custom dimensions/metrics, user properties, key events/conversions, and eCommerce tracking.
  • Develop custom GTM tags, triggers, variables, and JavaScript solutions where standard configurations are insufficient.
  • Implement end-to-end eCommerce tracking, including:
  • Product impressions/views
  • Product selection
  • Add/remove from cart
  • Checkout journey
  • Purchases/transactions
  • Promotions and campaign interactions
  • Work with DOM elements and browser events to capture dynamic user interactions.
  • Implement tracking for Single Page Applications (SPA) and dynamically rendered content.
  • Translate business and marketing measurement requirements into technical tracking specifications and implementation designs.
  • Work directly with front-end/eCommerce development teams to integrate tracking requirements into application code.
  • Diagnose and resolve JavaScript, DOM, API, CORS, network, dataLayer, and tag-firing issues.
  • Troubleshoot using browser Developer Tools, including Console, Network, Elements, Application/Storage, and debugging capabilities.
  • Implement and troubleshoot GA4 Measurement Protocol/API-based integrations where required. GA4 Measurement Protocol supports sending events to Analytics through HTTP requests and complements standard tagging approaches.
  • Implement cross-domain tracking and support complex multi-domain customer journeys.
  • Work with Consent Management Platforms (CMP) and implement consent-aware tracking.
  • Support integrations between GTM/GA4 and other advertising, personalization, eCommerce, and MarTech platforms.
  • Perform implementation QA and ensure tracking accuracy across development, test, acceptance, and production environments.
  • Create and maintain tracking specifications, dataLayer documentation, naming standards, and technical documentation.
