About Coris

AI risk and ops platform for Payment Processors, Banks, SaaS…. Backed by Y Combinator and Lux.

About the role

Own processor and platform integrations. Build and operate ingestion from Stripe, Adyen, Fiserv, TSYS, Repay, and new processors as we sign them: APIs, webhooks, and batch file feeds. Make them correct, idempotent, observable, and PCI-safe. Own the partner API and customer-specific work. Extend the v2 API, build per-customer configuration and signals, and work directly with customers' risk and ops teams to turn a vague report into a fix, fast. Found on 1752vc Careers, the job board for startup and VC roles.

  • Payments, merchant risk, underwriting, or fintech background (Stripe, Adyen, Plaid, Ramp, a PayFac or ISO)
  • Prior early-stage startup experience
  • Built a rules engine, signal pipeline, entity-linking / graph system, or feature store
  • SFTP and batch-file integrations, fixed-width or legacy formats, PCI-scoped data handling
  • Shipped LLM features in production - structured extraction, agents with tools, evals
  • Bias toward action and measurable impact, we ship fast, measure, and iterate with real customer feedback
More about this role

Coris is the AI platform for risk and financial operations. Platforms, marketplaces, payment providers, and banks - GoFundMe, Clio, Cherry, and a growing list - use Coris to onboard merchants faster, monitor them continuously, and act on fraud without adding headcount. One customer described us as "Cursor + Lovable for risk teams."

We're backed by Y Combinator, Lux Capital, and Pathlight, founded by payments-domain experts, and growing quickly on customer pull. We're a small team; this hire owns a large share of the backend.

Coris was started by Vinodh (CEO) and Shyam (CTO). We've each spent 20+ years in fraud and risk management, running risk engineering, operations and product teams at Google, eBay, PayPal and WePay. You'll work directly with both of us in Palo Alto.

Every Coris decision runs on data we pull from payment processors and platforms: Stripe, Adyen, Fiserv, TSYS, Repay, and more, over APIs, webhooks, and SFTP file feeds - hundreds of millions of events a month, billions of rows in Postgres. On top of that sits a signals and rules engine, an account graph, and the partner-facing API our customers build on.

Here's the honest version of the work. Files arrive out of...
