• Operating and improving internal data processing infrastructure

• Promoting the Lance format in open-source communities and at Big Data conferences

Requirements

• 5+ years of experience building high-performance databases, big data systems, or large-scale data services

• Deep understanding of internals of open-source Big Data or AI training systems (e.g., Hadoop, Spark, Flink, Ray, Iceberg, Delta Lake, Hudi, ClickHouse, Trino, Presto, PyTorch, or JAX)

• Strong experience with high-performance computing in Java or Scala

• Experience with Rust (or willingness to learn it)

• Proven ability to move fast, work independently, and collaborate with a high-caliber team

Nice to Have

• Contributor, committer, or PMC member in Apache or other large open-source projects

• Experience with Java, Rust, C++, Apache Arrow, DataFusion, Parquet, Iceberg, or Delta Lake

• Track record of driving large features or integrations in distributed systems

• Strong community presence and passion for open-source collaboration
