Senior Data Engineer — Measurement & Experimentation | 5-month contract | Fully remote (Europe)
A major European streaming group is rolling out a new recommendation model across three of its platforms. The model is built and tested. What’s needed now is the measurement framework that proves it actually moves engagement.
That’s this role. Two senior data engineers, joining an existing team, working to a tight delivery window.
What you’ll own:
The A/B testing framework, operational across three separate platform environments
Audience segmentation and activation — getting the right viewers into the right tests
ETL pipelines in Databricks (SQL and Python) feeding the experimentation layer
Optimizely SDK and webhook integration for test setup and measurement
Real-time engagement metric collection, dashboards and automated alerting on test health
Fine-grained permissions with OpenFGA across the analytics architecture
What we’re looking for:
Strong Databricks (SQL and Python) and production ETL experience
Hands-on experimentation work — A/B test infrastructure, not just reading the results
Optimizely or comparable experimentation platforms
Analytics architecture and real-time metrics at consumer scale
Senior enough to be productive in week one. The window is short and the goal is shipped measurement, not onboarding
The non-negotiable: AI literacy at L3 or above:
This client assesses AI practice on an internal scale, and L1 and L2 won’t be considered. L3 means you run full workflows with skills, sub-agents and MCP servers, and you build reusable AI artifacts that other engineers actually adopt — not just agent-mode coding on your own machine.
Candidates who orchestrate several agents in parallel are especially welcome.
Be ready to show concrete evidence: the skills, sub-agents, MCP servers or agentic workflows you’ve built and used on real projects. It gets explored properly at interview.
