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 answers questions the loan application didn't ask. For every business that crosses our queues, we need to know things that aren't on the form: what the business actually does, where it actually lives on the web, whether the people it names match the public record, and whether anything across the open web contradicts the story we were told. We answer those questions with LLM-driven agents that crawl, click, search, and extract structured evidence from across the web - and we treat this as a production data pipeline, not a research demo. We're hiring a Senior AI Engineer to own a slice of this enrichment surface end-to-end.
WHAT YOU'LL DO
- Own industry/category classification of businesses from heterogeneous signals (name, website, directory presence, reviews).
- Build and maintain discovery and verification systems for a business's real web presence - filtering aggregators, parked domains, brand collisions, and impersonators.
- Link individuals to businesses via public web evidence (e.g. confirming a named officer or employee genuinely works there).
- Develop risk/legitimacy scoring derived from web-presence signals, fed back into downstream underwriting.
- Build and evolve the shared agent infrastructure: provider-agnostic base agents, shared toolset registry (browser navigation, search, scraping, structured database lookups, scoring), eval harness, and instrumentation surface for token-and-tool tracing.
- Own model selection, agent design, prompt and tool engineering, eval methodology, and cost control across your enrichment surface.
MINIMUM REQUIREMENTS
- Shipped LLM-driven agents to production - not notebooks, not demos. Real users, real cost, real failure modes, real on-call.
- Strong async Python including structured-data libraries, modern web frameworks, and relational databases.
- Experience across multiple frontier LLM providers and at least one agent framework, with deep knowledge of failure modes.
- Built or maintained eval methodology: curated golden datasets, scoring functions, labelling guidelines, regression diagnostics.
- Browser automation experience: headless browsers, anti-bot evasion, authenticated flows.
- Holds informed opinions on structured-output reliability - when to use JSON-schema mode vs. function calling vs. extractor-on-top-of-text.
WHAT SETS YOU APART
- Web scraping at scale: anti-bot evasion, residential proxies, request fingerprinting, authenticated flows, CDN defeats.
- Eval-framework experience (e.g., LangSmith, Braintrust, Evals, or custom).
- Entity resolution / record linkage / fuzzy matching at scale.
- Browser-automation experience at the devtools-protocol level.
- Built a tool registry or toolset abstraction over multiple LLM providers.
- Cost/latency optimization: response caching, semantic caching, model routing (cheap-first then escalate), thinking-budget tuning, prompt-cache hit-rate work.
