- Create a Storage Operations Agent for incident triage, slow-query investigation, and remediation workflows

WHAT WE'RE LOOKING FOR

- Deep experience with data stores: Aurora RDS, Clickhouse, Kafka / AWS MSK, and Postgres

- Experience with table formats and lakehouse patterns, including Iceberg

- Strong coding in Python and Golang

- Infrastructure-as-code skills with Terraform

- 3-6 years at a successful tech company (Senior, Staff+)

BONUS POINTS

- 1-2 years at a data-focused startup (Databricks, Snowflake)

- Object and analytical storage experience: S3, GCS, Google BigQuery, AWS Athena, Presto, Parquet

- Vector and graph stores: VectorDB, Turbopuffer, Puppygraph

- A secondary spike in Observability Infrastructure
