WHY HARVEY At Harvey, we’re transforming how legal and professional services operate. 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. We have 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 moves fast, takes ownership, and is deeply committed to the mission — operating with intensity, staying close to our customers, and pushing each other for excellence. We live by three values: Decisiveness, Simplicity, and Job's Not Finished. We act quickly on clear judgment over perfect information, we believe simplicity is what scales, and we're never satisfied with where we are. If you want to do the best work of your career alongside people who share that drive, we'd love to build with you. At Harvey, the future of professional services is being written today — and we’re just getting started. ROLE OVERVIEW As a Senior Software Engineer on the Product Security team at Harvey, you'll be a key technical contributor shaping how security is built into our AI platform. 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 implement both technical controls and security features within the Harvey platform. 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.
