• 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
• Strong programming skills with demonstrated experience writing high-quality, production software
• Excellent communication and collaboration skills, particularly when translating security risks into business terms for non-security stakeholders
• (Desirable) Experience building security programs or practices at hyper-growth startups

• 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
• Define and own the product security roadmap, prioritizing initiatives based on risk, business impact, and engineering org maturity
• Establish and evolve security posture across the engineering organization, setting standards that scale with the company
• Partner with Product Engineering, Infrastructure, and Platform teams to incorporate secure design principles at every stage of development
• Own and review security-critical code across key parts of the product, including authentication and access control
• Architect secure-by-default libraries and tools that make the secure path the easiest choice for developers
• Drive mitigation strategies during security-related incident responses, coordinating cross-functional efforts
• Mentor engineers and raise the security bar across teams through code reviews, design reviews, and technical guidance
