## About the role

Baselayer is building the most comprehensive, accurate, and continuously-current identity graph of US businesses and consumers. Every entity, officer, address, relationship, and public record we can responsibly source - ingested, normalized, linked, and kept fresh. That graph powers fraud detection, KYB onboarding, portfolio monitoring, sanctions screening, and a growing surface of customer-facing API products.

## What they're looking for

- Shipped product features that touched ingestion to storage to API to customer, end-to-end, in production
- Owned a Postgres schema that real money or real decisions depended on, and stayed on top of its evolution
- Strong async Python with experience running async services at scale
- Deep Postgres expertise: schema design under live load, EXPLAIN ANALYZE as a reflex, zero-downtime migration tooling
- FastAPI (or close equivalent): shipped real APIs with auth dependencies, OpenAPI contracts, and structured response models
- Built multi-tenant APIs where access control is load-bearing and scoped correctly at the data layer
