Data Engineer role at focusing on streaming TV advertising infrastructure.

Обязанности

You'll join the Data Platform team, the group that owns 's entire data backbone: storage, batch compute, and the reporting stack that shows advertisers their performance in real time. You'll report to the Engineering Manager of Data Platform. This role exists because 's data volume has outgrown what most teams ever deal with: petabytes in storage and 500,000+ messages a second incoming, and it's still growing. That means the scaling problems here are real, not theoretical. You'll own systems end to end, from the first stakeholder conversation to the schema design to what happens when it breaks at 2am. And every dollar and millisecond you save shows up directly in the business, because data is the machinery runs on, not a support function bolted to the side.

Build the in-app reporting on an OLAP DB (ClickHouse).
Orchestrate jobs and move data around all the stack using batch or real-time approaches.
Identify and fix the pipelines or queries costing the most time or money
Instrument systems so cost and latency regressions get caught before they become incidents

Write and maintain the alerts and runbooks that keep the team ahead of problems
Build tooling, conventions, or data contracts that make the rest of the team faster

Push back on stakeholders when the right answer is "not yet" or "not this way"
Set the technical contract with the Front team for the reporting UI they build on top of your work
5+ years building and operating production data platforms at real scale, not analytics or BI-adjacent work
Deep lakehouse experience from both a storage angle (Iceberg, Delta, or Hudi) and a compute angle (Spark, DuckDB, or Trino)
Production experience with a modern orchestrator (Dagster, Airflow, or Prefect)
A specific, explainable story about a pipeline or query you made measurably faster or cheaper, and why it worked
On-call and incident response experience, including alerts or runbooks you actually wrote
Comfort adapting your communication for different audiences
