Key Responsibilities
Design and implement real-time and batch data pipelines
Build and maintain scalable streaming systems
Develop and optimize stream processing jobs
Ensure reliable ingestion from multiple internal and external data sources
Design event schemas and data contracts
Implement data validation, transformation, and enrichment logic
Optimize storage layouts and lifecycle management strategies
Improve system observability (metrics, logging, alerting)
Troubleshoot and resolve performance bottlenecks in distributed systems
Implement retry, dead-letter, and replay mechanisms
Ensure data quality, consistency, and governance
Collaborate with Backend, DevOps, and Security teams
Your skills and experience
Must-Have
Proficiency in Java, Python, and SQL; strong software engineering fundamentals
Experience with distributed messaging systems (e.g., Apache Kafka) and stream processing frameworks (e.g., Apache Flink)
Knowledge of event-time processing, windowing, state management, and handling out-of-order events
Experience with cloud storage/data lakes, relational databases, and search/indexing engines (e.g., OpenSearch / Elasticsearch)

Multi-tenant system design
Cost optimization in large-scale cloud environments
Soft Skills
Strong problem-solving and debugging skills in distributed systems
Ownership mindset with attention to reliability and quality
Clear communication and documentation skills
Ability to work cross-functionally
Comfort working in fast-paced environments
Qualifications
Bachelor's degree in Computer Science or equivalent experience.
7+ years of experience in data engineering or distributed systems
