Full Job Description
ABOUT BASELAYER Every day, financial institutions make consequential decisions about which businesses to onboard, extend credit to, and trust. Baselayer exists to make those decisions faster and more accurately. Our AI business identity platform is trusted by more than 2,200 financial institutions to verify any business, automate KYB, and monitor real-time risk. Our mission is to eliminate business fraud and lower the cost of trust across the financial system. ABOUT THE TEAM The team at Baselayer is built around people who care about getting things done right. We work closely with customers who have real compliance requirements and a limited tolerance for error, which means we move deliberately, communicate directly, and hold ourselves to a high standard. If you're someone who loves to take ownership and cares about the quality of what ships, let's chat! 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. We're hiring a senior engineer to own product 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 - matching the same business or person across sources where keys don't line up, names are misspelled, and addresses are formatted six different ways. Design and ship customer-facing APIs for search, lookup, monitoring, and webhook delivery - built for engineers who'
