Join FDIC-insured banks & non-bank lenders who automate 90% of manual effort in business loan origination with our AI-native Loan Origination System. Backed by Y Combinator.
About the role
The surface area is large and getting larger: a multi-tenant AI platform, a cloud estate under bank data-handling requirements, agents that read and act on customer data, and an engineering team shipping into all of it every day. Nobody can review their way across that. You build the guardrails, defaults, and tooling that scale past you. The AI attack surface. Prompt injection, tool-use abuse, exfiltration paths through agents, and the evals that tell you whether your controls hold.
What they're looking for
- Securing LLM or agentic products in production
- Standing up a security function at a fast-growing company
- Working inside or selling into regulated financial institutions: SOC 2, GLBA, FFIEC guidance, third-party risk, exam support
More about this role
Casca is building AGI for banking. We’re replacing decades-old legacy systems with AI-native technology that automates 90% of the manual work humans once had to do.
Our customers are FDIC-insured banks. Every one of them puts us through security review, control questionnaires, pen test results, and third-party risk assessment before we touch production. Then they hand us borrower tax returns, bank statements, and the data behind credit decisions on their own balance sheet.
So security isn't a compliance checkbox here. It's a precondition for the company existing. Every deal we win depends on it, and one bad breach ends the business.

Software. Detections, libraries, policy-as-code, automation, CI/CD checks — reviewed, tested, and deployed like any other service.
