Front-End Engineer

As a Front-End Engineer focused on tracking, you will implement and maintain accurate, event-driven tracking across modern front-end applications, ensuring that every user interaction, page event, API-driven event and marketing pixel fires correctly and consistently. You will collaborate with product, engineering, analytics, marketing and privacy teams to deliver clean, reliable and compliant data that powers analytics, optimization and customer experience.

Key responsibilities

• Implement front-end tracking across React, Angular and JavaScript applications.
• Build and maintain event instrumentation for page loads, clicks, product views, conversions and dynamic UI interactions.
• Integrate marketing pixels (TikTok, Meta, Pinterest, Symbiosis, etc.) using standardized event data.
• Validate and debug tracking using browser developer tools and tag management tools.
• Collaborate with engineering teams to ensure tracking is implemented correctly within front-end components.
• Ensure privacy compliance by integrating consent logic and preventing restricted data collection.
• Document tracking requirements, including event definitions, payload structures and implementation notes.

API-driven tracking

• Understand and interpret front-end API calls to determine when a request succeeds or fails.
• Extract the required data from successful API responses, such as order details, product lists, user state or transaction IDs.
• Trigger or update data layer events based on API success (e.g., Order Placed, Product Listing Displayed, User Authenticated).
• Map API response fields to event payloads for analytics, pixels and personalization systems.
• Ensure API-driven events fire only when the correct data is available and validated.

Required skills

• Strong JavaScript knowledge, including DOM events, async/await, promises and debugging.
• Good knowledge of AEM Cloud.
• Experience with React (components, hooks, lifecycle, event handling).
• Experience with Angular (components, services, observables, routing).
• Understanding of API calls, including response handling.
• Ability to extract and map API data into event payloads.
• Experience with tag managers such as Adobe Launch, GTM or Tealium.
• Knowledge of analytics platforms such as Adobe Analytics, GA4 or AEP.
• Attention to detail when validating event payloads and ensuring accuracy.
• Cross-functional communication with engineering, analytics, marketing and privacy teams.
