We push the limits to bring our app from “one of the top” to “the leader”.\nThe best way to describe Tango's work style is not to use the word “impossible”. We believe that success is a thorny path that runs on sleepless nights, corporate parties, tough releases, and of course our users' smiles (and as we are a LIVE app, we truly get to see our users all around the world smiling right in front of us in real-time!).\nDo you want to join the party?\nResponsibilities\nYou 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.\nBe the analytics counterpart for a product domain:\n1:1 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.\nRun A/B tests on product features, end to end:\nTurn 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.\nBuild and maintain the datasets behind your domain:\nWrite production transformations as SQL and YAML pipeline config, with freshness, uniqueness and validity checks. Your work goes through code review like any engineer's.\nSpecify instrumentation before it's built:\nWrite 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.\nRequirements\nAdvanced SQL, including window functions and multi-source joins - and the ability to reason about what a query costs, not only whether it returns.\nA 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.\n3+ years as a product or data analyst on consumer products, with real exposure to both mobile and web.\nCritical 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.\nComfort shipping code: git, merge requests, reading and reviewing someone else's SQL. You'll write production pipeline code, not only notebooks and queries.\nWorking knowledge of product event tracking: what a well-specified event looks like, and why the same event behaves differently across platforms.\nEnglish 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.\nStrong advantage\nBigQuery specifically - partitioned tables, clustering, slot-based pricing.\nAirflow, dbt, or another orchestrated transformation framework.\nHaving been the analyst on a production incident, not only in the post-mortem.\nNice to have\nPython with the usual statistical libraries - pandas, scipy, statsmodels.\nA 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.\nData quality tooling such as Soda or Great Expectations.\nExperience in social, live-streaming, gaming or another engagement-driven consumer product.\nWhat we offer:\nStock options grant (we’re a Silicon Valley Company)\nCompetitive salary\nMedical insurance for you and 75% off for your relatives\nOn-site position with 4 days at the office and 1 day WFH\nBudget for lunch\nParking\nMultisport card\nCheerful team spirit and fun office atmosphere\nIf this sounds like you, apply and help empower live entertainers and creators to build independent businesses around their live talents.","description_format":"text","description_chars":4804,"description_truncated":false,"requirements":{"experience_years_min":3,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[{"language":"English","level":"Intermediate (B1)","optional":false}]},"benefits":["Health insurance","Stock options"],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Streaming & OTT Platforms"],"lifecycle":[{"event":"open","at":"2026-09-26T15:13:26Z"}],"visa":[],"liveness":{"score":90,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.903,"p_room":1,"age_days":10,"expected_fill_days":46,"reasons":["conf:10","velocity","win:early"],"computed_at":"2026-10-03T05:45:00Z"},"pay":null,"html_url":"https://alion.io/job/tango-senior-data-analyst","json_url":"https://alion.io/job/tango-senior-data-analyst.json","meta":{"generated_at":"2026-10-04T02:16:49Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","usage":{"tier":"crawler","counted_by":"address","units_charged":1,"used_today":3199,"day_limit":5000,"remaining_today":1801,"minute_limit":60,"resets_at":"2026-10-05T00:00:00Z"}}}
