About the Role
We are looking for a Staff Software Engineer – Full Stack, based either in our offices in Paris, Barcelona or London, or remotely from France, Spain or the UK.
This role could sit within one of two teams: Session Analytics or Growth Ops, both currently looking for senior engineering talents.
- Session Analytics helps teams visually reconstruct user sessions and understand not just what users do, but why. The team powers key use cases across product, design, support, and engineering—surfacing friction points, reproducing bugs, and improving user experience. You’d join a cross-functional squad of 9 engineers (Front-end, full-stack and back-end), working closely with product managers and designers. In this role, you’ll help scale a system that processes millions of user sessions daily, combining high-throughput event ingestion, real-time processing, and smart replay rendering—all while maintaining strict privacy and compliance standards.
- Growth Ops supports and empowers other Growth Line (Acquisition, Activation, Retention, Referral, and Revenue) teams by coordinating cross-team efforts, building solutions for critical problems, and developing platform capabilities.
The team acts as a "glue", bridging gaps between Growth and other business areas, and ensuring systems are reliable, functional and performant. You'd join a cross-functional team of 6 engineers (full-stack and back-end), working closely with senior engineers and engineering managers. In this role, you'll work on best practice for fast-moving user interfaces, and bridging the gap between these and critical low-level services. You'll build strong relationships across the Growth teams, as well as the wider Engineering department, empowering individual contributors to solve problems and facilitate career growth opportunities.
