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 Harvey grows, we’re taking on increasingly complex, cross-functional programs that cut across teams and require dedicated end-to-end ownership. These range from opening new entities and markets, to M&A and integration work, to evolving the systems and providers that support our employees around the world. You’ll run point on some of our key operational initiatives: bringing structure to ambiguous problems, building the plan, coordinating work across functions, and driving decisions and execution. This is a hands-on program management role — you’ll work closely with functional experts, but you’re expected to get into the substance, develop a point of view, and personally step into gaps wherever needed to drive the program forward.
