About the Role:

We're hiring an exceptional Senior Data Engineer with deep data engineering expertise and strong, hands-on AI skills. You'll build scalable data infrastructure across ingestion, transformation, orchestration, and delivery — collaborating with backend, BI, and ML teams — while actively using AI tooling (Claude, Cursor, and beyond) as a core part of how you engineer and ship. Strong ownership mindset, data quality focus, on-call reliability, and a genuine drive to adopt modern AI tooling are a must.

Responsibilities:

• Design, build, and maintain scalable data ingestion and processing pipelines using SQL , Spark, Hadoop, Airflow, SnapLogic, or similar tools
• Optimize existing ETL/ELT workflows and resolve bottlenecks in production jobs
• Integrate multiple structured and unstructured data sources from internal and external systems

• Gather functional requirements, develop technical specifications, and own project and test planning
• Work in Agile/Scrum environments; help align team priorities across the organization
• Leverage AI-assisted dev tools (Claude, Cursor .. etc) to accelerate delivery and code quality

Required Skills :

• Strong Python, Advanced SQL, PySpark or Scala, Unix scripting
• Data orchestration: Airflow, SnapLogic, DBT, or equivalent
• Event bus & streaming: Kafka, AWS EventBridge, SNS/SQS, Kinesis, or similar
• Data lake & warehouse: Snowflake, Delta Lake, Redshift, BigQuery
• CI/CD tooling: Git, Jenkins / GitHub Actions, Docker
• Experience with APIs for data exchange and integration
• Data quality mindset, ownership, and SLA awareness
• NoSQL, Neo4j, GraphQL is plus

Preferred / Nice to Have :

• Experience with AI/ML models and feature pipelines
• Exposure to BI platforms (Tableau, Power BI) or data serving for dashboards
• Spark Streaming or Flink for stateful stream processing
