About the role
AI agents are beginning to act on behalf of people and businesses against publishers, banks, payment networks, and APIs. Every counterparty today answers identity questions on its own - self-asserted API keys, third-party cookies, pixel trackers. That model breaks the moment the actor is an agent. We're building KYA (Know Your Agent) - a cryptographic identity substrate that replaces self-assertion with third-party-issued credentials, verifiable by any counterparty.
What they're looking for
- Shipped systems where cryptographic correctness was load-bearing: OAuth/OIDC IdP, token issuer, signing service, HSM-backed signer, passkey/WebAuthn flow, or similar
- Fluent in Python and Go, or strong in one with a track record of learning the other quickly
- Reads RFCs as primary sources and holds informed opinions on JWK thumbprint canonicalization, pairwise-sub derivation, and Signature-Input header serialization
- Deep understanding of the distinction between identity and authorization, mandate and claim, snapshot and live state
- Production experience with async Python on Postgres, including migration safety and observability
More about this role
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 leading loan infrastructure providers. 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.
We're solving real-time entity resolution at a scale no one...
