Granica is hiring a Senior Software Engineer to build foundational lakehouse systems for AI. You will work on the core infrastructure behind Crunch , Granica’s continuous optimization product for enterprise lakehouse data.

- Production experience with modern data lake or lakehouse technologies such as Iceberg, Delta Lake, Hudi, Spark, Trino, Presto, Flink, Hive Metastore, Unity Catalog, or similar systems
- Hands-on experience with columnar formats such as Parquet or ORC
- Understanding of metadata-driven architectures, table formats, transaction semantics, query planning, and physical data layout
- Experience with table maintenance, compaction, clustering, file sizing, metadata pruning, snapshot expiration, or garbage collection
- Familiarity with cloud object storage systems such as S3, GCS, or ADLS and the performance tradeoffs of building lakehouse systems on top of them
