Serve as a technical leader and mentor—conduct design reviews, guide junior engineers, and influence the team's technical roadmap. Collaborate closely with data scientists, ML engineers, and product managers to translate business requirements into robust data models and pipeline specifications. Champion data governance, lineage tracking, and privacy-by-design principles across all data assets. Troubleshoot and resolve production incidents, perform root-cause analysis, and drive preventive improvements. Contribute to architecture decision records (ADRs) and technical documentation. What You Bring to the Team Required 8+ years of professional software or data engineering experience, with at least 4 years focused on cloud data platforms. Deep expertise with AWS data services: S3 (lifecycle policies, event notifications, encryption), AWS Glue (ETL jobs, Crawlers, Data Catalog, Glue Studio), and Amazon Athena (query optimization, workgroups, federated queries). Strong Python programming skills; proficiency writing production-grade PySpark or Spark (Scala) for large-scale data transformation. Solid SQL fundamentals—ability to write and tune complex analytical queries. Excellent communication skills—able to present technical trade-offs clearly to both engineering and non-engineering stakeholders. Proven experience mentoring engineers and leading technical design discussions. Bachelor's degree in Computer Science, Engineering, or a related technical field (or equivalent practical experience). Nice to Have Experience with real-time / streaming data processing using Apache Kafka, Amazon Kinesis, or AWS Glue Streaming ETL. Familiarity with AWS Lake Formation for fine-grained access control and data governance. Knowledge of Amazon Redshift or other cloud data warehouses.
