Job DescriptionThe Opportunity: We're hiring a Data Engineer II to own the analytics backbone for our growing mobile free-to-play portfolio. You'll design and operate the pipelines, data models, and quality systems that turn raw telemetry into trustworthy, analyst-ready datasets - so studio teams can make sharper decisions about retention, monetization, and engagement across titles. This is a build-while-running role: you'll keep existing pipelines healthy, migrate legacy infrastructure onto our partner-managed ETL platform, and stand up new capabilities alongside it.
What Your Impact Will Be: Run & Optimize - Live Data ETL Framework - Configure and operate the partner-managed ETL framework for mobile game telemetry ingestion and transformation
- Maintain silver/gold transformation layers in BigQuery using SQL and orchestration tooling, applying schemas optimized for analytical queries
- Optimize BigQuery performance and cost through partitioning, clustering, materialized views, and query tuning
- Design curated data marts as data products - with clear owners, documentation, and SLAs - that power Mixpanel dashboards and enable analysts to self-serve on retention, monetization, and engagement metrics
Migrate & Extend - Migrate legacy Airflow pipelines to the partner platform for existing and licensed titles without disrupting live reporting
- Partner with game studios and Data Analysts on tracking plans - defining events, properties, validation rules, and data contracts that keep downstream consumers insulated from upstream change
- Build data quality and observability systems that reduce time-to-detect and time-to-recover for telemetry issues before they reach reporting
- Contribute to team engineering practices - code review, documentation standards, onboarding - and pragmatically apply AI and LLM tooling to accelerate SQL authoring, validation, and documentation
QualificationsWhat We're Looking For:- 4+ years as a Data Engineer or Analytics Engineer shipping production data pipelines
- Expert SQL and strong Python, with hands-on experience in BigQuery and Airflow / Cloud Composer
- Demonstrated expertise in medallion architecture, dimensional modeling and data warehouse optimization
- Mobile F2P analytics experience - fluency with event telemetry, player lifecycle metrics (retention, LTV, ARPDAU), and game economy KPIs
- Hands-on working knowledge of GCP-native tooling
- Track record of building data quality and observability systems: validation, anomaly detection, SLAs, and operational hygiene
- Solid production engineering practices - version control, code review, CI/CD, and environment management for data pipelines
- Comfort operating within a partner-managed ETL framework and coordinating across studio, analytics, and infrastructure teams
- Strong collaboration and communication skills; high-ownership working style with comfort in ambiguous problem spaces
- Working knowledge of privacy and compliance fundamentals
- Bachelor's degree in Computer Science, Engineering, Information Systems, or a related field
Nice to Have:- Experience with dbt (data build tool) for transformation orchestration
- Familiarity with mobile attribution SDKs (Adjust, AppsFlyer, Kochava) and attribution modeling
- Familiarity with mobile game revenue data - in-app purchases and ad monetization
- Experience with data observability platforms
- Fluency with Mixpanel as a downstream consumer of the data you build; exposure to Tableau or Looker
