About You

• Significant professional experience building production data systems and pipelines. We level on scope and judgment rather than years.

• Proficient in Python and SQL for large-scale data processing.

• Proficient in Kubernetes-native batch orchestration and modern data lake technologies (Argo Workflows, Metaflow, EKS, Glue, Athena, Apache Iceberg, Parquet, DuckDB, Terraform). Airflow or Dagster experience transfers fine.

• Demonstrated experience designing stable identifiers for a large, changing corpus, and building validation that gates a publish rather than reporting on it after the fact.

• Experience putting an LLM or agent component into a production data path, including the eval loop, the gold set, and cost per record.

• Daily use of AI coding tools, paired with healthy skepticism about their output on questions of production data correctness.

• A track record of owning work through to a running, validated system, including the unglamorous parts: fixing the malformed dataset, writing the backfill, debugging last night's bad publish.

• Comfort with messy scientific formats and toolchains (mzML, RDKit, ProteoWizard or similar). Engineering depth is the requirement.

• A passion for contributing to an early-stage startup where autonomy, eagerness to learn, and enthusiasm for solving novel scientific challenges prevail over rigid processes and egos.
