With our core product Playtime Arcade, we've become the global leader in rewarded advertising, an ad unit built on a simple premise: users earn real in-app rewards for engaging with new apps. The result is one of the most effective value exchanges in adtech, connecting advertisers and publishers with over 770 million users annually.\nInvestigating 770 Million User Interactions Across a 100TB Data Lake\nWhen a platform serves 770 million users, every optimization from reward mechanics to SDK integrations needs to be grounded in data. The Rewarded Analytics team builds the internal dashboards, alerting systems, and data pipelines that monitor the user funnel, traffic engagement, and reward consistency.\nSQL and Python power deep-dive investigations and automated100 terabyte-sized data analyses queried through Trino. Using Tableau as the main visualization tool, stakeholders have access to real-time insights on the product performance. Airflow orchestrates the pipelines that keep everything up to date. This team provides the data that turns questions into answers: every A/B experiment the product team runs, every anomaly a publisher flags, and every new SDK integration. These answers guide all the business decisions.\nYour Mission & Who We Are Looking For:\nData analyst with a strong technical foundation. You have 5+ years as a Data Analyst and work fluently in both SQL and Python, writing complex queries, big data optimizations, and analysis pipelines to support product and growth initiatives.\n\nMaster of experimentation and A/B testing. You have deep experience designing experiments, calculating sample sizes, managing variance reduction techniques, and analyzing A/B/n tests to ensure statistically sound business decisions.\n\nStatistically grounded. You can reason confidently about core statistical concepts-hypothesis testing, confidence intervals, p-values, power analysis, and Bayesian vs. Frequentist approaches-and apply them to real-world product decisions.\n\nNot a stranger to anomaly detection. You have experience working with anomaly detection algorithms and approaches like distribution analysis and cross-population comparison to monitor test guardrail metrics and identify unexpected shifts in experiment data.\n\nYou own the systems, not just your slice. You understand the end-to-end telemetry and feature flagging systems that power experimentation. You can speak to data flows, event tracking pipelines, architecture tradeoffs, and why things were built the way they were.\n\nAutomation-minded across the stack. You think beyond one-off test analyses and build automated experiment reporting dashboards, reusable analytical frameworks, and data visibility solutions. Experience with dbt, Airflow, or experiment platforms (e.g., Optimizely, GrowthBook) is a strong plus.\n\nCollaborative and business-aware. You work closely with product managers, engineers, and growth leads to translate complex statistical results into clear, actionable recommendations that drive executive decision-making.\n\nWe welcome applications from talent worldwide and provide relocation support to Hamburg, Germany for those ready to join our team.\nWhat’s in It for You?\nAt adjoe, you’re not here to just close JIRA tickets, you’re helping build the infrastructure behind one of the most impactful platforms in adtech. The systems you work on will reach hundreds of millions of users and power billions of decisions every day.\nGo Big. Own projects with impact on 770M users and push adtech boundaries.\n\nMove Fast. Ship solutions multiple times a day, learn from results, and keep momentum.\n\nBe Direct. Solve problems openly and collaborate across teams.\n\nThrive Together. Grow with a diverse, global team of people from over 40 different countries that learn from each other.\n\nHave Fun. Celebrate wins, enjoy daily victories, and bring your energy.\n\nWe welcome applications from people who will contribute to the diversity of our company.","description_format":"text","description_chars":4020,"description_truncated":false,"requirements":{"experience_years_min":5,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"master","optional":false},"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[{"name":"Germany","iso":"DE","kind":"country"}],"hiring_excludes":[],"relocation_offered":true,"industries":["Advertising","Digital Marketing"],"lifecycle":[{"event":"open","at":"2026-08-14T12:05:42Z"},{"event":"close","at":"2026-10-07T16:34:33Z"},{"event":"reopen","at":"2026-10-09T18:25:26Z"}],"visa":[],"liveness":{"score":37,"band":"fade","label":"Fading","p_open":1,"p_active":0.848,"p_room":0.44,"age_days":77,"expected_fill_days":69,"reasons":["conf:2","velocity","win:tail","crowd:"],"computed_at":"2026-10-31T05:58:55Z"},"pay":null,"html_url":"https://alion.io/job/applike-group-senior-data-analyst-experimentation-ab-testing-fmd","json_url":"https://alion.io/job/applike-group-senior-data-analyst-experimentation-ab-testing-fmd.json","meta":{"generated_at":"2026-10-31T11:58:53Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","about":"Alion is a live layer of people, companies and AI agents: who they are, whether they are real and active right now, what they do and how to work with them, readable by people and by agents and paid per call.","catalog":"https://alion.io/catalog.json","usage":{"tier":"crawler_verified","counted_by":"address","units_charged":1,"used_today":18502,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-01T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.02,"usd":0.002,"plus_per_slice":{"credits":0.05,"usd":0.005}},"unit":"per company, plus each slice with data","note":"the employer in depth","call":{"mcp_tool":"get_company","arguments":{"id":51964},"rest":"https://alion.io/mcp/rest/get_company?id=51964"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fapplike-group-senior-data-analyst-experimentation-ab-testing-fmd"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":1,"usd":0.1},"unit":"per slice","note":"pay, demand and time to fill for this role and place","call":{"mcp_tool":"market_stats"},"human":"https://alion.io/catalog?offer=market.stats&for=job%2Fapplike-group-senior-data-analyst-experimentation-ab-testing-fmd"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.02,"usd":0.002},"unit":"per posting in a list","note":"similar open postings","call":{"mcp_tool":"search_jobs"},"human":"https://alion.io/catalog?offer=job.search&for=job%2Fapplike-group-senior-data-analyst-experimentation-ab-testing-fmd"},{"id":"company.verify","title":"Is this company real and active right now","status":"pilot","price":null,"unit":"per company","request":{"url":"https://alion.io/catalog/request","method":"POST","body":"{\"offer\": \"company.verify\", \"for\": \"job/applike-group-senior-data-analyst-experimentation-ab-testing-fmd\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fapplike-group-senior-data-analyst-experimentation-ab-testing-fmd"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":142721}},{"tool":"search_jobs","arguments":{"company":"applike-group.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":142721},"note":"people open to offers who fit this vacancy"}],"note":"The same data through MCP tools: https://alion.io/mcp/open needs no sign-in (compact searches, postings, people); https://alion.io/mcp with an Alion account has everything.
