## About the role

**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 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.

**ABOUT THE TEAM**

---

We're solving real-time entity resolution at a scale no one else has cracked — fusing dozens of data sources into a single business identity graph and resolving any entity in milliseconds. It's a graph AI problem, a retrieval problem, and a fraud-modeling problem stacked on top of each other. The technical depth is real.

You'd be joining a small team where the data moat is defensible, the research problems are open, and the infrastructure you build becomes load-bearing for businesses. Ownership is real. Velocity is real. There's no layer of process between an idea and shipping it.

We're at an inflection point — the graph is built, the match rates speak for themselves, and the hardest problems are still ahead: graph embeddings, fraud propagation models across the business network, real-time traversal at sub-100ms latency, and expanding the identity layer beyond finance into every platform that needs to trust a business.

If you want to work on something foundational — the kind of infrastructure that gets built once, and everything else runs on top of — this is it.

**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.

**COMPENSATION**

---

- Salary Range: $230k – $340k + Equity

**B****ENEFITS**

---

- Time off when you need it: Flexible PTO so you can recharge without red tape

- In-person energy: We're based in SF and meet in the office 4 days a week

- Competitive compensation: We pay well and back it with equity. We want you to think and act like an owner

- Career rocket fuel: You'll help build the foundation of a high-growth startup, working side by side with experienced founders and team members who've done it before

- Benefits on us: We cover 100% of your health, dental, and vision premiums. No surprise deductions from your paycheck

- 401(k) with company match: We match your contributions so your future self benefits too

- HSA contributions included: We contribute to your HSA on applicable plans, so your coverage works as hard as you do

- Stay healthy, stay sharp: A $250 monthly gym stipend to help you bring your best self to work, and everywhere else

- A seat at the table: We believe in transparency, radical candor, and giving every team member a voice 🔥
