Senior Software Engineer - TAG team

Mission 🚀

• The Tag group develops a TypeScript tracker collecting anonymous data to feed Contentsquare SAAS products. It respects privacy, personal user information, internet security protocols and regulations. It collects all the user interactions (pageviews, clicks, mouse movements, scrolling, ...) of the web visitors of our thousands of enterprise-grade clients (i.e. Microsoft, Verizon, Wallmart, HSBC, Disney, Ikea, ...) and millions of small and medium businesses (through the acquisition of Hotjar and Heap).
• As the tracker is loaded and executed on millions of user sessions a day, the Tag group is driven by three main pillars: code quality, security, and performance.
• We pay a lot of attention to performance, compatibility with all available browsers and versions, support for the diversity of front-end frameworks, anticipation of new rules and regulations to foresee future developments that could break the functioning of our data collection.
• The data flow that powers Contentsquare Products naturally starts with the tracker, giving it a critical role in the construction of our product portfolio. We are proud to continuously enrich our product functionalities linked to session replay recordings, tag configurator capabilities, error tracking, merchandising data collection and so on, while guaranteeing the leanest impact on customer websites.
• In the last years and even more so with Project One, the Tag group has embarked on an ambitious mission: Deliver the best-in-class Tag, recognized as such by our customers, the analytics market and our competitors! 🚀

What's in the DNA of this team?

• Quality! Since the first days at CS, the Tag team has developed a high level of code quality, respecting the SOLID principles, adopting Clean Architecture and test automations.
• Web expertise! We sit at the forefront of web development, solving uniquely hard problems and pushing back the limits of the possible.
• Continuous improvement! We truly want to stand best in the industry and leave the competition behind, by fostering a continuous & data-driven improvement approach.


• The Tag group is organized in two Units:
• Tag Core, whose mission is to consolidate the technical foundations of the tracker (Architecture, Performance, Scalability, CI/CD)
• Tag Functions, whose mission is to develop all the product functionalities to feed the whole system.
This job posting is for a Senior Software Engineer role within the Tag Core Unit.
