Cloud data warehouses have no on-premise equivalent, so this is a ground-up engine design, not a re-point. It is the single longest-lead technical track in the program, and the decisions you make on catalog, engine placement, and pipeline redesign gate everything downstream: transforms, serving, and reporting.\nA Day in the Life\nOwn the lakehouse reference architecture: Iceberg table design, Trino cluster topology, catalog service, Spark transform compute, and object-storage layout. \nDesign on-premise replacements for cloud-managed warehouse capabilities that have no direct equivalent: change-data-capture streams, scheduled tasks, and write-back paths into operational stores. \nRun proof-of-concept validation of the catalog and query engine at expected data volumes, and define evidence-based triggers for placement decisions (VM-based versus Kubernetes-native operators). \nSet platform-wide standards for table layout, partitioning, file sizing, and Iceberg maintenance: compaction, snapshot expiry, and orphan-file cleanup. \nLead the SQL dialect strategy for porting existing warehouse workloads to Trino and Spark SQL. \nMentor senior engineers across data workstreams, review designs, and raise the bar on engineering quality. \nPartner with platform engineering on storage sizing, resource isolation, and capacity planning for the lakehouse footprint. \nWhat You Need\nB.E., B.Tech., M.Sc. degree in Computer Science or a related technical field. \n12+ years of industry experience building and operating large-scale data platforms or distributed systems. \nDeep, hands-on expertise with distributed SQL engines: Trino/Presto or Spark SQL internals, query planning, and performance engineering. \nProduction experience with Apache Iceberg (or Delta Lake/Hudi with willingness to go deep on Iceberg): table spec, merge-on-read versus copy-on-write, and table maintenance at scale. \nWorking knowledge of Iceberg catalog services (REST catalogs such as Polaris or Nessie, or Hive Metastore) and S3 compatible object storage. \nStrong understanding of cloud warehouse internals (Snowflake, BigQuery, or Redshift) sufficient to design functional equivalents on open-source infrastructure. \nProfessional software development experience with Java and/or Python. \nExperience delivering data platforms in on-premise, regulated, or air-gapped \nenvironments is a strong plus; healthcare data experience is a plus.\nWe offer competitive benefits to set you up for success in and outside of work.\nHere’s What We Offer\nGenerous Paid Time Off: Recharge and relax with 20 days of fixed time off per year, in addition to company holidays-because we believe work-life balance fuels performance.\nBest-in-Class Parental Leave: Spend quality time with your growing family. We offer one of the industry’s most generous parental leave policies to support you during life’s most important moments.\nRecognition & Rewards: We celebrate wins-big and small. Get rewarded with monetary incentives and company-wide recognition for your impact and dedication. Your hard work won’t go unnoticed.\nComprehensive Insurance Coverage: Stay covered with medical, dental, and vision insurance, plus 100% company-paid short- and long-term disability and basic life insurance. Optional perks include discounted legal aid and pet insurance.\nInnovaccer Inc. is an equal opportunity employer.
