- Secure & govern: Apply best practices for IAM, data masking, encryption, and compliance with NDPR and company policies.
- Collaborate & enable: Partner with our business units to define datasets, publish documentation, and enable self-service.
- Automate the platform: Use CI/CD and Infrastructure-as-Code to provision and maintain data infrastructure reliably and use tools for workflow orchestration.
- Continuously improve: Profile workloads, tune jobs, and reduce costs while improving reliability and performance.

- Database Management: Strong SQL and hands-on experience with both relational (e.g., Postgres, MySQL, SQL Server) and NoSQL stores (e.g., MongoDB, Cassandra, DynamoDB).
- ETL/ELT Processes: Proven experience designing and operating Extract–Transform–Load workflows (batch and streaming).
- Data Modelling: Solid grasp of data modelling concepts and techniques (OLTP vs. OLAP, dimensional modelling, normalization).
- Automation: experience in creating automation with scripting and Microsoft Power Apps.
- Cloud Computing: Working knowledge of AWS, Azure, or Google Cloud services for data engineering (e.g., S3/ADLS/GCS, EMR/Databricks/Synapse/BigQuery, MSK/Kinesis/Pub/Sub).

- BI exposure (Power BI, Looker, Tableau, Qlik Sense) and ML feature pipelines (Feast, Tecton) a plus.
- Domain experience in automotive, aftermarket, logistics, or multi-site service networks.
