About the role

EcoVadis, a provider of business sustainability ratings, is strengthening its Product Analytics team in Barcelona with a Web Tracking Engineer. You will be the hands-on integration owner of the end-to-end digital tracking strategy that captures quantitative data across EcoVadis customer platforms.

Key responsibilities

• Collaborate with Product Managers and engineering teams to implement HTML, CSS and JavaScript tagging for user interactions, including adoption and usage of AI-powered features.
• Integrate with engineering teams so that customer dimensions and demographics are passed accurately to the product analytics tool (Pendo) for segmentation.
• Define and implement digital metrics frameworks and data layer specifications across frontend and backend tracking, keeping schemas validated, version-controlled and documented, and protecting personal data.
• Configure, QA and deploy front-end A/B tests and feature flags, ensuring reliable variant assignment, exposure tracking and conversion measurement.
• Build workflows where AI agents draft tracking specs, run synthetic regression tests with headless browsers (e.g. Playwright) and monitor event volumes for anomalies.
• Debug tag firing, network payloads and integration errors, and orchestrate data flow between the analytics tool, CDP, experimentation tools and the data platform.

Required profile

• Comfortable working in both front-end code and data architecture.
• Empathetic communicator who thrives in collaborative environments and acts as a technical consultant to non-technical stakeholders.
• Meticulous, with a strong commitment to data integrity and data privacy (GDPR, CNIL).
• Fluent in English; the position is open only to candidates eligible to work and live in Spain.

Required skills

• Strong JavaScript / TypeScript, HTML, CSS and the DOM, including tracking in single-page applications.
• Hands-on experience with a product or web analytics platform (Pendo preferred; Amplitude, Mixpanel, Hotjar or Google Analytics also valued).
• Familiarity with tag management systems (Google Tag Manager, Adobe Launch) and CDPs.
• Experience configuring client-side A/B tests and feature flags, and implementing server-side tracking.
• Use of AI coding assistants and agentic tools; experience building agentic workflows or MCP integrations is a plus.
