Lead Data Engineer Role: Lead Data Engineer Experience: 68 years Location: Bengaluru / Hybrid Employment: Full-time Role Summary We are looking for a Lead Data Engineer with strong hands-on experience in real-time data streaming, event processing, CDC, data integration, and modern data engineering.

The Lead Data

Engineer will be responsible for designing, developing, and maintaining high performance data pipelines using Apache Flink, Apache Kafka, Debezium, CDC, ClickHouse, and Apache Airflow. This is a hands-on engineering role requiring strong practical experience in building production grade streaming applications, developing data pipelines, troubleshooting distributed systems, and optimizing data processing workloads. The ideal candidate should be comfortable working across the full data pipelinefrom source systems and CDC ingestion through Kafka and Flink processing to analytical storage, APIs, dashboards, and downstream integrations.

Key Responsibilities Real-Time Data Engineering • Design, develop, and maintain real-time data pipelines using Apache Flink and Apache Kafka.

- Develop production-grade streaming applications for high-volume and low-latency workloads.
- Implement data transformation, filtering, enrichment, aggregation, and event processing.
- Build reliable event-processing pipelines with appropriate error handling and recovery mechanisms.
- Consume and publish events across Kafka topics.
- Implement appropriate partitioning, consumer groups, offsets, and delivery mechanisms.
- Troubleshoot streaming pipeline failures and performance issues.

- Troubleshoot CDC failures and source-to-target data issues. Data Orchestration • Develop and maintain data workflows using Apache Airflow or equivalent orchestration frameworks.
- Build reusable DAGs for: o Data ingestion o CDC workflows o Data validation o Flink job execution o Data transformation o ClickHouse loading o Downstream integrations • Implement workflow dependencies, scheduling, retries, backfills, SLAs, and alerting.
- Integrate Airflow workflows with Kafka, Flink, Debezium, ClickHouse, APIs, and cloud services.
- Monitor workflow execution and troubleshoot failures.
- Develop reusable operators, sensors, and workflow components where appropriate.
- Use event-driven triggers where real-time workflows require them. ClickHouse &
- Analytical Data • Integrate streaming data pipelines with ClickHouse.
- Design efficient analytical data models.
- Develop and optimize SQL queries.
- Implement appropriate partitioning, sorting, indexing, and retention strategies.
- Optimize data ingestion and query performance.
- Support downstream analytical use cases, dashboards, and reporting requirements. Data Quality &
- Reliability • Implement data validation and quality checks throughout the pipeline.
- Build reconciliation mechanisms between source and target systems.
- Monitor data freshness, completeness, accuracy, and consistency.
- Implement error handling, retry, replay, and recovery mechanisms.
- Establish logging and observability for critical pipelines.
- Support incident investigation and root-cause analysis. Integration &
- APIs • Integrate streaming and analytical data with APIs, endpoints, dashboards, and downstream applications.




- Develop data interfaces and integration components.
- Work with application teams to define data contracts and integration requirements.
- Support future integrations and additional data consumers.

Engineering

Practices • Follow modern software engineering practices around: o Git o Code reviews o Unit testing o Integration testing o CI/CD o Logging o Monitoring o Documentation • Develop reusable and maintainable data engineering components.
