The team and your role

We are looking for a highly motivated individual to join the Publisher Activation team based in Ghent.

The Publisher Activation team is dedicated to creating new integrations and tools that assist our customers, the publishers, in using our measurement technologies. To gather the necessary metrics for our measurement services, we directly integrate with the native browser APIs on the client-side. On the server side, we have multiple components that further process the requests initiated by our client-side scripts.

Our technology stack is built for scale and reliability. We use GitLab for version control and collaboration, with CI/CD and Infrastructure as Code (Terraform) powering our deployment pipeline. Grafana and Prometheus give us real-time visibility into our systems, while Google Cloud Platform and Cloudflare provide our serverless infrastructure. We store our data in BigQuery and rely on tools like Ox, Jest, and Playwright for testing and security. We also make heavy use of AI coding agents like Claude, Copilot, and Cursor to accelerate our development.
