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)
