Qualifications: - 7+ years of software engineering experience. - Strong experience in Python, Scala, Java, or another JVM language. - Experience with Spark or another distributed data-processing framework. - Experience building or operating production data platforms, backend systems, or distributed systems. - Familiarity with at least 1 of these areas: Lakehouse architecture, Apache Iceberg, data quality, governance, lineage, metadata, query engines, or real-time OLAP. - Working knowledge of AWS services such as EC2, S3, Athena, and IAM. - Experience improving production reliability through monitoring, alerting, deployment automation, and incident response. - Strong analytical, communication, and collaboration skills. - Experience with Kubernetes, Terraform, Airflow, Trino, ClickHouse, Starrocks, or Pinot is a plus.
