We're looking for a Data Infrastructure Engineer to build and maintain high-performance data lakehouse infrastructure. You'll develop reliable data maintenance workflows for Apache Iceberg, covering compaction, snapshot expiry, manifest rewriting, and orphan file cleanup, with a strong focus on data integrity and correctness.
This role combines distributed data systems with open-source development. You'll also contribute to a Rust-based, multi-engine SQL query router, maintaining connectors, reviewing community contributions, and shaping the product roadmap.
