We’re a fast-scaling legal tech SaaS company. Our platform is deeply embedded in the disputes function across major law firms. We are now launching a major initiative to expand our solution across new legal workflows, including additional contentious practices and transactional teams. This role is a key contributor to that initiative. As a Principal Product Manager, you will lead ecosystem-level initiatives that shape how our platform connects, extends, and creates value beyond its core boundaries. This role operates with high autonomy and strategic scope, driving product bets that sit at the intersection of platform architecture, interoperability, and emerging AI-powered workflows. You will own and evolve foundational ecosystem capabilities, including APIs, integrations, data ingress and egress, and developer experience; while navigating a fast-changing landscape where traditional API design increasingly intersects with AI-first platforms and autonomous tooling. Principal PMs are senior individual contributors who combine systems thinking, deep discovery, and hands-on execution to deliver transformational, platform-wide impact.

Own success measures for initiatives, including ARR, adoption, retention, or TAM expansion
