Our social casino products operate on a virtual-coin economy with live ops, missions, and promotions. We are also developing mystery-box ecommerce brands where customers purchase boxes containing real physical products.<br \/>Data drives our product decisions: which players and buyers to acquire, which promotions to run, and how to keep each economy healthy. You&#x27;ll be responsible for making that data reliable and turning it into actionable insights.<\/p>\n<p>What You&#x27;ll Do<br \/>Build and Run the Pipelines<br \/>Own ingestion into ClickHouse and BigQuery from PostgreSQL and MongoDB change-data-capture, client and server events, payment providers, and AppsFlyer.<br \/>Run and extend the Airflow DAGs that build our bronze, silver, and gold layers. Make every job idempotent, backfillable, and monitored.<br \/>Add freshness and quality checks, and alert when a table is late or wrong.<br \/>Make ClickHouse our main analytics warehouse in place of BigQuery, starting with our mystery-box products.<br \/>Design ClickHouse schemas, sort keys, materialized views, and retention for events, orders, and wallet data.<br \/>Migrate pipelines, models, and dashboards, and run both warehouses side by side until the numbers match.<br \/>Keep BigQuery reliable and cost-controlled while the social casino products still run on it.<br \/>Build the Business Analytics<br \/>Maintain the KPI layer leadership uses to run the company: DAU, revenue, retention, LTV, ROAS, and economy health.<br \/>Move reporting off Tableau and older analytics tools onto our own AI dashboards, built in-house on the tables you create.<br \/>Answer ad hoc questions for product, live ops, marketing, and finance.<br \/>Design A\/B tests and promotion experiments, and interpret their results accurately.<br \/>Work with the Product Teams<br \/>Agree on event schemas and tracking with backend and client engineers before a feature ships.<br \/>Define metrics consistently and document every table so all teams and AI dashboards report the same numbers.<\/p>\n<p>Questions You&#x27;ll Answer<br \/>These are examples of the questions you&#x27;ll own, from the pipeline to the answer.<br \/>Social Casino<br \/>Which acquisition sources pay back, and by which day?<br \/>How do missions, promotions, and coinback change retention and spend?<br \/>Is the virtual-coin economy inflating?<br \/>Where do new players drop off in their first session?<br \/>Mystery-Box Ecommerce<br \/>Which boxes convert from view to purchase, and why?<br \/>How does the value of the products received compare with box prices across different tiers?<br \/>Do referrals and promotions bring repeat buyers or one-time discount hunters?<br \/>Which countries and devices grow fastest?<br \/>Company<br \/>What is one revenue and margin view across all products for the CEO and CFO?<br \/>Which metrics should every team report the same way?<br \/>Our Data Stack<br \/>Sources: PostgreSQL (transactions, wallets, payments), MongoDB (missions, segmentation, analytics projections), client and server events, AppsFlyer.<br \/>Ingestion: Change-data-capture mirrors of PostgreSQL and MongoDB into ClickHouse and BigQuery; Airflow for scheduled jobs.<br \/>Main Warehouse: ClickHouse, replacing BigQuery, with mystery-box products moving first. It also holds our telemetry through OpenTelemetry (ClickStack).<br \/>Legacy Warehouse: BigQuery, organized in bronze, silver, gold, and semantic layers until the migration is complete.<br \/>Cloud: Google Cloud and AWS.<br \/>Products: TypeScript backends, React web apps, native mobile apps.<br \/>Dashboards: In-house AI dashboards built on ClickHouse and BigQuery tables, replacing Tableau and older analytics tools.<\/p>\n<p>What You Bring<br \/>6+ years of experience in data engineering, analytics engineering, or a data analyst role where you built and owned production pipelines.<br \/>Expert SQL, including window functions, cohort queries, and query-plan tuning.<br \/>Production ClickHouse: MergeTree table engines, sort keys, materialized views, and TTLs. Having led a warehouse migration is a strong plus.<br \/>Production experience with BigQuery: partitioning, clustering, scheduled jobs, and cost control.<br \/>Python for pipelines, and an orchestrator such as Airflow. dbt or a similar modeling tool is a plus.<br \/>Change-data-capture or event streaming from operational databases (for example, Datastream, Debezium, Pub\/Sub, or Kafka).<br \/>Data modeling you can defend: layered or dimensional models, slowly changing dimensions, safe backfills.<br \/>Product analytics: retention cohorts, LTV, ARPDAU, funnels, and A\/B test design with a correct read of significance.<br \/>Analytics that go beyond a BI tool: you design the tables, metric definitions, and queries an AI dashboard can answer from correctly. Tableau experience helps with the migration.<br \/>English: Upper-Intermediate (B2) or higher.<\/p>\n<p>Nice to Have<br \/>Social casino, free-to-play, or mobile gaming analytics: virtual-currency economies, live ops, payer conversion.<br \/>Ecommerce or mystery-box analytics: conversion funnels, average order value, repeat purchase, box value versus price, promotion and referral attribution.<br \/>Mobile measurement partner data (AppsFlyer or similar), user acquisition, and ROAS modeling.<br \/>OpenTelemetry or ClickStack, and observability data at volume.<br \/>Infrastructure as code (Terraform) on Google Cloud or AWS.<br \/>Enough TypeScript to add or fix an event at the source.<br \/>Privacy-safe data handling: PII separation and account-deletion requests.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>We&#x27;re hiring a Senior Data Engineer \/ Data Analyst to&#8230;<\/p>\n","protected":false},"author":13890,"featured_media":0,"parent":0,"comment_status":"open","ping_status":"closed","template":"","meta":{"_mo_disable_npp":"","rwu_salary_min":0,"rwu_salary_max":0,"rwu_salary_currency":"","rwu_salary_period":"","rwu_english_level":"B2","rwu_experience_months":72,"rwu_candidate_countries":"","rwu_company_type":"\u041f\u0440\u043e\u0434\u0443\u043a\u0442\u043e\u0432\u0430 \u043a\u043e\u043c\u043f\u0430\u043d\u0456\u044f","rwu_industry":"gambling","rwu_part_time":false,"rwu_source_views":42,"rwu_source_applications":4,"rwu_source_category":"Data Analyst","rwu_source_name":"Djinni.co","rwu_source_url":"https:\/\/djinni.co\/jobs\/856585-senior-data-engineer-data-analyst\/","rwu_apply_url":""},"job_category":[57],"job_type":[54],"class_list":["post-4128371","job","type-job","status-publish","hentry","job_category-programuvannia","job_type-povna-zainiatist"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v28.8 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>Senior Data Engineer\/Data Analyst, (\u0432\u0456\u0434\u0434\u0430\u043b\u0435\u043d\u043e) | Remote Work Ukraine<\/title>\n<meta name=\"description\" content=\"\u0412\u0456\u0434\u0434\u0430\u043b\u0435\u043d\u0430 \u0432\u0430\u043a\u0430\u043d\u0441\u0456\u044f Senior Data Engineer\/Data Analyst \u0443 .
