Entain NCE · Tallinn, EE ·
We’re looking for a Data Quality & BI QA Engineer to help us scale trusted reporting across the NCE region. You’ll ensure KPIs are consistent across reports, data values/types match requirements, and Power BI semantic models and dashboards remain reliable as our BI team. Our core stack is Power BI + Snowflake + ClickHouse, with automations in Python.
Job responsibilities:
Conduct manual testing of BI functionality and reporting requirements (functional/nonfunctional where relevant), including semantic model, KPI validation, measures (DAX), dashboards, and recurring reports.
Create, execute, and maintain test scenarios, test cases, and regression suites for KPIs, filters, drilldowns, and cross-report consistency.
Validate that data values and data types match requirements; ensure KPI definitions remain consistent across reports and releases: reconcile totals, drill-down logic, filters/slicers, time logic, rounding rules, segmentation consistency across reports.
Use SQL to reconcile results, identify mismatches, and support root-cause investigations in Snowflake/ClickHouse.
Gradually introduce automated data quality checks (SQL/Python), covering freshness, completeness, duplicates, schema changes, and threshold/anomaly detection.
Collaborate with BI developers and data engineering to clarify requirements, log defects, validate fixes, and improve overall data quality.
Maintain testing documentation and evidence (e.g., in Jira/TestRail) and support a clear release sign-off approach.
Our expectations:
2+ years of experience in QA/testing (software/functional) and strong interest in data/BI quality.
Strong SQL skills for reconciliation and investigation, ability to debug metric mismatches end- to-end (grouping, joins, window functions).
Hands-on understanding of BI/reporting logic and how KPIs can break (filters, granularity, semantic layer).
Power BI experience (testing semantic models, validating DAX measures, performance awareness).
Programming/scripting (Python) is an advantage; automation will be introduced gradually.
Experience with Snowflake / ClickHouse, dbt tests, GitHub, or data quality frameworks.
Great attention to detail, clear communication, ability to challenge inconsistencies constructively.
Required competencies:
Breaks down complex problems into clear, actionable tasks.
Proactive, resourceful, and takes ownership end-to-end.
Manages multiple priorities without sacrificing quality or deadlines.
Collaborative team player who elevates shared goals and outcomes.
Strong quality mindset and respect for delivery timelines.
We offer:
Great opportunity to take part in the development of a growth- and innovation-driven company and build its future.
Dynamic work in a rapidly growing international company with personal development possibilities.
Professional team with various international backgrounds to collaborate.
Opportunity for career development.
Wide benefits package: annual company performance bonus, extra day off on your birthday, dedicated days off for your physical and mental health, additional vacation days depending on the length of employment, health insurance policy, wellness and team-building events, dedicated budget for your training and development, paid online consultations with certified therapists and so much more!
