• Monitor and troubleshoot issues in live systems and continuously improve their robustness.
• Work cross-functionally to ensure data is accessible, well-modeled, and easy to consume by other teams.

Requirements

• Strong programming experience in at least one of the following: C++, Java, Rust, .NET, or Python.
• Experience working with python data analytics libraries (such as numpy, pandas, polars).
• Experience working on backend services or data-intensive applications.
• Understanding of distributed systems, data pipelines, and production monitoring.
• Experience in hybrid infrastructure environments (on-prem + cloud).
• An open-minded technologist with a willingness to learn and adopt new technologies and best practices.

Nice to Have

• Familiarity with Apache Iceberg or other table/data format technologies (e.g., Delta Lake, Hudi, Parquet, ORC).
• Familiarity with Streaming technologies – Kafka, Flink.
• Experience with orchestration tools like Airflow or Argo.
• Exposure to analytics engines (e.g., Spark, DuckDB, Trino).
• Knowledge of Kubernetes and containerized deployments.
• Experience in MLOps or supporting machine learning pipelines.
