• Build scalable systems across Spark, BigQuery, Airflow, and Postgres that process and enrich billions of daily events with low latency and high reliability
• Optimize the performance and cost of data workflows across Kafka, BigQuery, Aerospike, and other distributed systems
• Debug production issues, participate in code reviews, and write clean, testable, and maintainable code
• Work cross-functionally with Product, Data Science, and Engineering teams to solve business-critical problems

What we're looking for

• 5+ years of experience as a Data Engineer or Backend Software Engineer working on distributed systems or large-scale data pipelines
• Proficiency in Python or Java, with strong software engineering fundamentals and clean coding practices
• Experience with streaming frameworks such as Apache Beam, Flink, or Spark, and messaging systems like Kafka
• Comfortable working with SQL, nested data, and analytics platforms like BigQuery
• Familiarity with cloud infrastructure (GCP preferred), Docker or Kubernetes, and CI/CD workflows
• Strong debugging and system optimization skills
• A self-starter who thrives in a collabo
