Senior Web Tracking Engineer (Product Analytics)

Job Description

EcoVadis Tech team, led by our Chief Product & Technology Officer, is responsible for overseeing the Product & Tech strategy, solution roadmap, and cross-company coordination to drive commercial success of our product. The Tech team develops scalable client solutions that enable all companies to effectively measure, manage and continuously improve their sustainable business practices. We provide industry-leading solutions for sustainability ratings, by evaluating & providing recommendations to improve environmental, social, ethical and procurement practices, while building a suite of solutions to help decarbonize supply chains around the world.

To further support the product growth and experimentation strategy, we are strengthening our Product Analytics team through the recruitment of a Web Tracking Engineer. As a member of the Product Analytics team, you will hold a key role by being the hands-on integration owner of the end-to-end digital tracking strategy to capture quantitative data across the EcoVadis customer platforms.

What you’ll be doing every day:

• Collaborate: with Product Managers & engineering teams to understand new feature implementation specificities and implement the HTML, CSS, and JavaScript tagging required to track user interactions, including measuring adoption and usage of the AI-powered features we ship.

• Integrate: and work closely with our engineering teams to ensure that relevant customer dimensions and demographics are accurately passed to our product analytics tool (Pendo) to allow for robust customer segmentation.

• Govern: Define and implement digital metrics frameworks and data layer specifications across both client-side (frontend) and server-side (backend) tracking setups. Keep schemas strictly validated, version-controlled and documented clearly enough that both people and AI tools can use the data correctly, and ensure personal data never flows where it shouldn't.

• Experiment & Deliver: Partner with Product Managers, analysts and engineering teams to configure, QA, and deploy front-end A/B tests and feature flags using tools like Experimentation/AB testing tools. Ensure rock-solid variant assignment, exposure tracking and conversion measurement without introducing flicker or layout shifts, and make sure experiment data lands reliably in our data platform.

• Support & Automate: act as a technical point of reference on web analytics, identifying and suggesting new technical solutions to solve challenges. This includes building workflows where AI agents speed up tracking work: drafting tracking specs from product requirements, driving headless browsers (e.g. Playwright) to run synthetic regression tests for tracking QA, and monitoring event volumes for anomalies.

• Troubleshoot: Actively debug, test, and troubleshoot tag firing, network payloads, and integration errors to safeguard data collection health.

• Orchestrate: the flow of data between key systems (product analytics tool, CDP, experimentation tooling, data platform), monitoring integration health and troubleshooting issues to ensure a reliable system integration. As more usage happens through APIs and agents rather than the UI, you'll make sure our server-side tracking captures it.

• Be: who you are and bring your true-self at work to add your uniqueness to a fun crew of data lovers. Ability to communicate in poignant gifs is a big plus.

Who you are:

• A professional who is comfortable working in both front-end code and data architecture.

• An empathetic communicator that thrives in collaborative environments and wants to set your peers up for success.

• A strong problem-solver with the diagnostic skills to debug complex, multi-system data flow issues.

• An initiative-taker that likes environments with responsibilities, and the space to express & act on your own ideas.

• A meticulous, detail-oriented individual with a deep-seated commitment to ensuring data integrity from the point of capture.

• Someone who uses agentic tools in your daily work and stays critical of them: you know when to rely on their output and when to check it.

Qualifications

• Strong proficiency in JavaScript / TypeScript, HTML, CSS and the DOM, including tracking in single-page applications.

• Hands-on experience with a product or web analytics platform (Pendo preferably, though relevant experience with competitors like Amplitude, Mixpanel, Hotjar or Google Analytics is valuable), and familiarity with tag management systems (e.g. Google Tag Manager or Adobe Launch) and CDPs.

• Practical experience configuring and deploying client-side A/B tests or feature flags, including debugging flicker and validating variant bucketing.

• Experience implementing server-side tracking and a solid understanding of APIs for troubleshooting system integrations.

• Technical Debugging: Strong diagnostic and troubleshooting skills using browser developer tools and network proxies to inspect tracking payloads.

• A strong understanding of data privacy regulations (e.g., GDPR, CNIL) and their practical implementation in data collection.

• Practical experience with AI coding assistants and agentic tools (e.g. Claude Code, or equivalent) to write, review, test and debug code faster, plus the judgment to validate what they produce. Experience building your own agentic workflows or MCP integrations is a plus.

• The ability to act as a technical consultant to non-technical stakeholders (e.g., Product, Marketing).

• Be fluent in English (as our primary working language).

Even if you don't 100% meet all of the points above, we'd love for you to get in touch! We're always looking for a diverse set of talents who can bring their unique perspective to the team!
