Job description

ABOUT BASELAYER Every business in America needs a bank account to exist. The system that decides whether they're real, who's behind them, and whether they're a risk, runs on infrastructure from the 1980s. We're rebuilding that layer from scratch. Baselayer is the identity layer for institutions across the United States: the most complete business graph in America and every human tied to it. We fuse public records, IRS data, sanctions lists, web signals, and fraud telemetry from 2,200+ financial institutions into a single graph that resolves any business and the humans behind it in milliseconds. The legacy credit bureaus took 50 years to build something that gets 60% match rates. We've built something that gets 98% in under two years. Today we're trusted by over 20% of financial institutions in America including FIS, Rho, Socure and top five US banks. But the graph is becoming infrastructure for anyone who needs to know if a business is real and worth trusting: gig platforms, marketplaces, AI companies, and commerce infrastructure at scale. Trust is the substrate of every financial transaction. We're rebuilding it. ABOUT THE TEAM AI agents are starting to transact: opening accounts, buying services, moving money on behalf of the businesses and people behind them. Every one of those transactions has a counterparty asking the question banks have always asked: who am I dealing with, and can I trust them? Today's identity infrastructure wasn't built to answer it at agent speed. The Agentic Economy team is extending Baselayer's business graph into the trust layer for agentic commerce: verifiable credentials that bind an agent to the verified business and human behind it, a registry counterparties can query in real time, and verification APIs that plug into the networks, platforms, and protocols where agent transactions happen. We run like a startup inside a startup: a small senior team led by our GM of Agentic Economy, working directly with payment networks, banks, wallet providers, and agent platforms. The category is being defined right now; the standards, seats, and infrastructure decisions of the next 18 months will be consequential for a decade. 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'll be live in production within a day of signing up. Own schema design and zero-downtime migrations on a database hot 24/7. Optimize performance and scale: query patterns for 10x volume, ingestion pipelines that finish before the next batch arrives, API latencies that don't drift as the graph deepens. Build multi-tenancy and access control: every query in the system scoped by org/user/permission at the data layer. MINIMUM REQUIREMENTS 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. WHAT SETS YOU APART Entity resolution / record linkage / fuzzy matching at scale. Search infrastructure - full-text, fuzzy, or vector - kept in sync with a Postgres system of record. KYC/KYB/fraud/underwriting data-pipeline experience. Address parsing/normalization at country scale. Webhook delivery infrastructure: retries, signing, idempotency, and ordering guarantees. GCP experience with Cloud Run, Cloud Tasks, Cloud SQL, and batch pipelines. WORK LOCATION Based in SF; hybrid 4 days per week in office.
