Baselayer is building the most comprehensive, accurate, and current identity graph of US businesses and consumers. Every entity, officer, address, relationship, and public record we source is ingested, normalized, linked, and refreshed. This graph powers fraud detection, KYB onboarding, portfolio monitoring, sanctions screening, and a growing set of customer-facing API products. We are hiring a Senior Software Engineer to own features across that surface end-to-end: schema design, data ingestion, entity resolution, API endpoints, scope and multi-tenancy, and performance under real customer load.

What you'll do: - Ingest and normalize heterogeneous public records into the graph, owning the full pipeline: ingestion to normalizer to repository to API surface. - Build and maintain entity resolution and linking systems to match the same business or person across sources where keys don't line up, names are misspelled, or addresses are formatted differently. - Design and ship customer-facing APIs for search, lookup, monitoring, and webhook delivery—built for engineers who'll be live in production quickly. - Own schema design and zero-downtime migrations on a database that runs 24/7. - Optimize performance and scale: handle high-volume query patterns, ensure ingestion pipelines finish before the next batch, and keep API latencies stable as the graph grows. - Build multi-tenancy and access control: ensure each query is scoped by org/user/permission at the data layer.

Minimum requirements: - Shipped end-to-end product features from ingestion to storage to API to customer in product
