Задачи:

You own a business domain — the numbers in it, the events behind them, the pipelines that build them, and the experiments that change them. This is not a reporting role with a ticket queue. Be the analytics counterpart for a product domain: 1:1 chat, content packs, negotiations, live streaming — you become the person PMs and engineers come to for any number in that area, and the person accountable when it's wrong. Run A/B tests on product features, end to end: Turn a product hypothesis into a test: primary and secondary metrics, the minimum effect worth detecting, and the audience. Confirm the population split and assignment events are genuinely correct before trusting the readout. Monitor it while it runs, then deliver a clear ship / don't-ship call and the reasoning behind it. This is a large part of the job, not an occasional project. Build and maintain the datasets behind your domain: Write production transformations as SQL and YAML pipeline config, with freshness, uniqueness and validity checks. Your work goes through code review like any engineer's. Specify instrumentation before it's built: Write the BI event spec for new features across Android, iOS and Web; then verify after release that events actually fire the way the spec said, and chase the gaps when they don't.

Требования:

Advanced SQL, including window functions and multi-source joins — and the ability to reason about what a query costs , not only whether it returns. A strong experimentation background. Hypothesis testing, confidence intervals, power and minimum detectable effect — and the failure modes: peeking at a running test, multiple comparisons, hunting for a segment where the result works. You should also be the kind of person who checks that the experiment itself is sound before trusting its numbers. 3+ years as a product or data analyst on consumer products, with real exposure to both mobile and web. Critical use of AI analytics tooling. We use an internal Claude-based layer over BigQuery heavily. We want someone who checks what it produces before passing it on. Comfort shipping code: git, merge requests, reading and reviewing someone else's SQL. You'll write production pipeline code, not only notebooks and queries. Working knowledge of product event tracking: what a well-specified event looks like, and why the same event behaves differently across platforms. English at B1 or above. You'll write specifications that engineers build from and present findings to product stakeholders, so clear written English matters more than fluent speech. Будет плюсом: BigQuery specifically — partitioned tables, clustering, slot-based pricing; Airflow, dbt, or another orchestrated transformation framework; Having been the analyst on a production incident, not only in the post-mortem; Python with the usual statistical libraries — pandas, scipy, statsmodels; A BI tool such as Looker, Tableau or Power BI — having built the models and dashboards, not only read them. We use Looker today but are moving off it, so the particular tool matters much less than having done the work in one; Data quality tooling such as Soda or Great Expectations; Experience in social, live-streaming, gaming or another engagement-driven consumer product
