Key Responsibilities

• Design, build, and evolve scalable data warehouse architecture and data models, including raw, staging, core/conformed, and mart layers.
• Develop and maintain reliable batch and/or streaming data pipelines, ensuring scalability, performance, and data quality.
• Drive the migration and consolidation of legacy data pipelines and platforms, including validation, reconciliation, cutover, and decommissioning.
• Establish consistent data definitions, metrics, and modelling standards across business domains.
• Build data quality frameworks covering automated testing, freshness monitoring, anomaly detection, and reconciliation.
• Partner closely with Analytics, BI, Product, Engineering, and business teams to translate data requirements into scalable solutions and enable self-service analytics.
• Improve data discoverability and usability through certified datasets, documentation, semantic models, and reusable data assets.
• Contribute to engineering best practices through architecture/design reviews, technical standards, and mentoring of other Data Engineers.

Requirements

• Minimum 7+ years of Data Engineering experience, building and operating large-scale data systems.
• Expert knowledge of data warehousing methodologies (Dimensional Modeling, Star/Snowflake Schema, Data Vault).
• Hands-on experience with modern big data stacks: Hive, Spark, Flink, Kafka.
• Deep familiarity with cutting-edge OLAP engines and lakehouse technologies: ClickHouse, StarRocks, Greenplum, Iceberg, or Hudi.
• Strong proficiency in advanced SQL, query performance tuning, and complex ETL/ELT pipeline optimization.
• Proficiency in modern workflow orchestration and transformation tools, specifically Airflow and dbt (Data Build Tool), to manage, schedule, and test complex data pipelines.
• Proven ability to solve complex data problems and partner effectively with Engineering, Analytics/BI, Product, and business stakeholders.

Preferred Qualifications

• Experience in data migration projects, dependency mapping, cutover strategy, dual-running, reconciliation, and decommissioning.
• Experienced in developing cost-saving strategies for AWS Databricks, GCP BigQuery and Tableau
• Experience in OTA, travel tech, e-commerce, marketplace, fintech, or other high-volume transactional environments.
• Experience in one or more of: data warehouse architecture, large-scale data migration/pipeline consolidation, or analytics enablement.
• Exposure to CDC, streaming, semantic/metrics layers, or advanced data modelling.
• Experience leading technical designs, setting engineering standards, or mentoring other Data Engineers.
