Staff Software Engineer, Product Security

Why Harvey

At Harvey, we’re transforming how legal and professional services operate — not incrementally, but end-to-end. By combining frontier agentic AI, an enterprise-grade platform, and deep domain expertise, we’re reshaping how critical knowledge work gets done for decades to come.

This is a rare chance to help build a generational company at a true inflection point. With 1000+ customers in 58+ countries, strong product-market fit, and world-class investor support, we’re scaling fast and defining a new category in real time. The work is ambitious, the bar is high, and the opportunity for growth — personal, professional, and financial — is unmatched.

Our team is sharp, motivated, and deeply committed to the mission. We move fast, operate with intensity, and take real ownership of the problems we tackle — from early thinking to long-term outcomes. We stay close to our customers — from leadership to engineers — and work together to solve real problems with urgency and care. If you thrive in ambiguity, push for excellence, and want to help shape the future of work alongside others who raise the bar, we invite you to build with us.

At Harvey, the future of professional services is being written today — and we’re just getting started.

Role Overview

Some of the world's largest companies and their law firms use Harvey’s AI capabilities to deliver world-class client services at unprecedented scale and efficiency. Harvey allows high-performing professionals to gain deep domain knowledge faster, understand the big picture, and tackle more complex challenges in less time. 

Our customers depend on us to deliver a secure, trustworthy, and compliant platform. Earning the trust of our customers is a business enabler and we value it more than anything else.

As part of the Product Security team, you’ll help ensure Harvey is built in the most secure way possible. You’ll take ownership of securing a specific part of the product and build strong relationships with the developers working in that area. With these insights, you’ll advocate for and implement high-leverage security controls across the organization.

Our security program at Harvey 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.
