About the Role We’re looking for a Senior Data Engineer to help design and build scalable, cloud-native data platforms on AWS. This is a hands-on engineering role where you’ll work on modern lakehouse architectures, open table formats (Iceberg), and compute environments running on EKS/Argo Workflows. You’ll have the opportunity to make a big impact—shaping architecture that sets the standard for the next five years. If you thrive in fast-paced, collaborative environments and love solving complex data challenges, we want to hear from you. Key Responsibilities + Design and implement AWS lakehouse architectures using services like S3, Glue, Athena, Lake Formation, and more. + Build ETL pipelines and production-grade data workflows. + Develop modular, testable Python code for data engineering tasks. + Implement open table formats (Apache Iceberg preferred) with features like time travel and schema evolution. + Apply Medallion architecture (Bronze → Silver → Gold layers). + Handle Slowly Changing Dimensions (SCD Type 2) in distributed systems. + Collaborate with tech leads, architects, and product managers. What We’re Looking For + 4–5+ years in data engineering with AWS. + Advanced Python engineering skills (not SQL-heavy DBA or analyst roles). + Expertise in AWS services (S3, Glue, Athena, Lake Formation, etc.). + Experience with ETL pipelines and orchestration (bonus: EMR on EKS or Argo Workflows). + Familiarity with open table formats (Iceberg, Delta Lake, or Hudi). + Strong communication and documentation skills. Nice to Have: + DataOps practices, CI/CD for data pipelines. + Terraform or CloudFormation experience. + Data quality frameworks (Deequ, Great Expectations). Why You’ll Love This Role: You’ll be part of a collaborative, fast-paced team running SAFe Agile, with ownership and initiative at the core of the culture.
