Staff Software Engineer, Product Security

Harvey•New York, NY

About The Position

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. You'll take ownership of securing critical parts of the product while driving high-leverage security initiatives that raise the bar for the entire engineering org — balancing hands-on technical work with cross-functional leadership and mentorship. 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.

8+ years of experience in product security, application security, offensive security, and/or security-focused software engineering
Long track record of identifying and remediating software vulnerabilities, demonstrated through CVEs, bug bounty awards, published research, or prior work experience
Track record of leading complex cross-functional security initiatives and delivering measurable improvements, with demonstrated ability to influence engineering teams without direct authority.
Experience mentoring senior engineers and developing security talent within an engineering organization

Experience with AI/ML systems and emerging security considerations for LLM-based applications
