Senior Software Engineer — Lakehouse Systems

Granica is hiring a Senior Software Engineer to build foundational lakehouse systems for AI. This includes systems for metadata management, transaction semantics, table maintenance, object-store-backed storage layouts, file optimization, and lakehouse cost/performance across petabyte- and exabyte-scale environments. You will own core systems that directly affect customer infrastructure cost, query performance, table reliability, and the operational health of large lakehouse environments.

Deep engineering experience in distributed systems, storage systems, databases, or data infrastructure. Production experience building, extending, or deeply optimizing lakehouse or table-format systems such as Iceberg, Delta Lake, Hudi, or similar technologies. Strong understanding of metadata architectures, transaction semantics, snapshots, manifests, schema evolution, and physical data layout.
