ROLE OVERVIEW As a Staff Software Engineer on the Product Security team at Harvey, you'll play a critical role in shaping how security is built into our AI platform from the ground up. We store and process our customers’ most sensitive data, and as a result, security is paramount at every stage of our product lifecycle.

This is a rare opportunity to define and build a product security program at a company scaling fast. Our security program is driven by our collective offensive security experience: breaking into systems at other companies (in white-hat capacities), responding to real security incidents, and learning from other companies’ data breaches. We regularly conduct penetration tests and red team exercises with external security firms. At the same time, we are all software engineers - contributing code daily and approaching security with an engineering-first mindset.
