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
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. We're hiring an engineer to own a meaningful surface of the substrate - issuer mint, edge verification, Passport, or Merkle audit log - and ship it to production.
WHAT YOU'LL DO
- Build and maintain the runtime issuer/mint: OAuth Token Exchange (RFC 8693), JWS credentials (RFC 7515/7519, SD-JWT-VC), and Merkle audit log with real-time revocation.
- Own and evolve the wire format and claim registry: JWT profile, verification_level/verification_method enums, and eIDAS/NIST IAL/FATF CDD crosswalk.
- Implement sub-millisecond JWS verification and Web Bot Auth signature checks (RFC 9421) at the HTTP edge for counterparty CDNs, merchants, and publisher paywalls.
- Build and maintain Passport - the user's cloud-resident principal account with canonical handle, KYC/KYB record, authorized-operators list, audit feed, and authenticator binding.
- Develop operator integration: embedded KYB onboarding inside first OAuth 2.0 consent, per-operator opt-in, and webhook delivery via Svix.
- Work across a Python 3.13 monorepo (FastAPI, Cloud Tasks, Cloud Run, SQLModel/SQLAlchemy) and Go for performance-critical substrate components.
MINIMUM REQUIREMENTS
- 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.
WHAT SETS YOU APART
- Verifiable credentials / SSI / DID work - especially SD-JWT-VC, OID4VC, or the W3C VC stack.
- Certificate Transparency, Trillian, or similar append-only-log experience.
- KYC/KYB pipeline experience: provider abstraction, evidence retention, eIDAS/FATF CDD level mapping, ownership-chain resolution.
- Edge/CDN engineering - Cloudflare Workers, Fastly Compute, Envoy filters, or mTLS at the edge.
- Familiarity with AP2, x402, MPP, UCP, or Mastercard VI specs and how identity rides alongside mandate.
