LanceDB is the AI-native Multimodal Lakehouse: one system where a researcher curates petabytes of video, audio, and every signal derived from them with a few lines of Python, and the next training run starts as fast as the next idea. Customers like Runway, Midjourney, and Netflix build the future of AI on LanceDB, from frontier and world models to robots and autonomous vehicles.\nAbout the Role\nWe're looking for a Senior Software Engineer to help expand the reach of Lance and LanceDB within the broader data infrastructure ecosystem. You'll work at the intersection of high-performance computing, big data, and open-source systems. You will contribute scale and performance improvements, integrations with the wider data and AI ecosystem, simplifying distributed operations, and usability and maintainability enhancements.\nWhat You'll Do\nDesigning and maintaining efficient distributed Lance dataset operations\n\nBuilding efficient indices to enable predicate pushdown and accelerate queries in Spark, Ray, or Trino\n\nWorking on table formats, data encodings, and various aspects of the Lance format in Rust\n\nDriving open-source community efforts to integrate the Lance format with Spark, Hive Metastore, Presto, Trino, Ray, and other data infrastructure systems\n\nOperating and improving internal data processing infrastructure\n\nPromoting the Lance format in open-source communities and at Big Data conferences\n\nWhat We're Looking For\n10+ years of experience building high-performance databases, big data systems, or large-scale data services\n\nDeep 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)\n\nStrong experience with high-performance computing in C++, Java, and/or Scala\n\nExperience with Rust (or willingness to learn it)\n\nProven ability to move fast, work independently, and collaborate with a high-caliber team\n\nNice to Have\nContributor, committer, or PMC member in Apache or other large open-source projects\n\nExperience with Apache Arrow, DataFusion, Parquet, Iceberg, or Delta Lake\n\nTrack record of driving large features or integrations in distributed systems\n\nStrong community presence and passion for open-source collaboration","description_format":"text","description_chars":2371,"description_truncated":false,"requirements":{"experience_years_min":10,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Data Warehouses & Lakehouses","Databases & DBMS","Vector Search & RAG"],"lifecycle":[{"event":"open","at":"2025-10-25T11:10:55Z"},{"event":"open","at":"2026-09-26T11:36:55Z"}],"liveness":{"score":8,"band":"cold","label":"Long shot","p_open":1,"p_active":0.277,"p_room":0.28,"age_days":340,"expected_fill_days":42,"reasons":["conf:1","win:tail","crowd:"],"computed_at":"2026-10-01T05:45:00Z"},"pay":{"stated_usd_annual":250000,"is_top_pay":true},"html_url":"https://alion.io/job/lancedb-senior-software-engineer","json_url":"https://alion.io/job/lancedb-senior-software-engineer.json","meta":{"generated_at":"2026-10-01T10:35:03Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","usage":{"tier":"crawler","counted_by":"address","units_charged":1,"used_today":1684,"day_limit":5000,"remaining_today":3316,"minute_limit":60,"resets_at":"2026-10-02T00:00:00Z"}}}
