Security Lead

Petual is the AI-powered control tester for the modern enterprise. We automate the most labor-intensive work in internal audit and governance: testing whether a company's financial, operational, and technology controls are effective as designed.

The hard part isn't exclusively speed of processing over a massive data set, it's also correctness. Our agents reason over messy, unstructured evidence screenshots, ledgers, ticket exports, and PDFs to reach a conclusion, and trace all reasoning to the source. When the evidence doesn't support a conclusion, we have to be precise about why, and what would need to be different to support a different outcome.

External auditors re-perform our work, so "mostly accurate" means we’re failing.
We're backed by Andreessen Horowitz, First Round Capital, Cowboy Ventures, Elad Gil, and some of the best angel operators in the valley.

We’re hiring a Security Lead to build and own the security function ’ll inherit a strong technical baseline infrastructure as code, established cloud and app-security practices, an early compliance program from a team with roots at Retool and Lyft. From there, you’ll set the strategy, strengthen our posture, and take us through the compliance frameworks needed to serve regulated industries like banking and federal work.
