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. With 1500+ customers in 60+ 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 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, Frontend at Harvey, you will own and lead engineering projects that define the user experience of our different products: Assistant, Vault, Workflows, and Harvey in Microsoft Word and Outlook. You will also lead frontend engineering on new products that we are building at Harvey. The team is composed of highly motivated, skilled, and considerate engineers. Everything we touch is polished to high standards extending to all aspects of our work – from design to architecture to code to slack communication. If any of this resonates with you, this role might be right for you.
