• Integrate diverse data sources (CRM, payment gateways, affiliates, game providers, and marketing platforms).
• Implement data quality, monitoring, and governance standards across the data stack.
• Collaborate with BI, Product, and Marketing teams to deliver clean and trusted data models.
• Support performance tuning, cost optimization, and security within the AWS data ecosystem.
• Mentor junior engineers and participate in data architecture discussions.

• AWS: Redshift, Glue, Lambda, S3, Athena, Step Functions, EMR, DMS
• Data Modeling / Transformation: dbt, SQL, Python
• Warehousing: Snowflake, Redshift

• Competitive salary and performance-based bonus
• Opportunity to build and scale a modern AWS data stack from the ground up.
• Access to cutting-edge tools, training, and certifications.
• Dynamic, international team culture within a fast-growing iGaming organization.

We are continuously improving our data architecture and are looking for someone who can lead these initiatives:

• Reduce Data Lag:
  Migrate to real-time data replication using DMS, Fivetran CDC, Debezium + Kafka, or AWS DMS to achieve low latency.
• Optimize Data Modeling:
  Leverage dbt to transform raw Snowflake data into analytics-ready models, improving maintainability and reducing BI layer load.
• Tune BI Layer(Quick Suite):
  Use SPICE for summaries (with incremental refresh) and Direct Query for real-time dashboards. Implement visual refresh intervals and dataset partitioning for optimal QuickSight performance.
