Designing and improving our lakehouse architecture using technologies like Apache Hudi . Working with query engines such as Presto / Trino for large-scale analytical workloads. Building and maintaining orchestration workflows using Apache Airflow . Creating reusable data models, curated datasets, and reliable data marts for analytics and product teams. Improving data platform reliability, observability, SLA tracking, lineage, and data quality checks. Optimizing storage, compute, query performance, and pipeline costs. Partnering with product, analytics, ML, and backend engineering teams to understand data needs and convert them into scalable platform solutions. Driving engineering standards around data modeling, schema evolution, partitioning, deduplication, backfills, replayability, and pipeline ownership. Mentoring data engineers and influencing architecture decisions across teams. What We’re Looking For Must Have Strong experience in data engineering , preferably at scale. Hands-on experience with Apache Airflow or similar orchestration systems. Strong knowledge of Presto / Trino or other distributed query engines.
