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.
What you'll be doing
Customer & Market Discovery
- Identify whitespace opportunities across the broader ecosystem
- Lead deep discovery with customers, partners, and internal teams to understand how data enters, exits, and interoperates with the platform across varying technical maturity levels.
- Translate insights into clear strategic recommendations and validated ecosystem initiatives
Strategy & Vision
- Define the long-term vision for the platform ecosystem, including APIs, integrations, data exchange, and extensibility.
- Connect the dots between traditional API design, AI-powered integrations, and emerging paradigms such as agent-driven or autonomous tool interactions.
- Identify where extending workflows beyond the platform create meaningful customer and business value and where it does not.
- Ensure ecosystem investments align with company strategy, platform principles, and client trust requirements.
Execution & Delivery
- Own the end-to-end strategy, roadmap, and delivery of ecosystem capabilities, including APIs, integrations, data ingress and egress, and platform interoperability.
- Define and sequence initiatives that balance foundational platform improvements with experimentation, innovation pilots, and strategic partnerships.
- Lead complex, cross-team initiatives from discovery through launch and iteration, managing dependencies across Product, Engineering, Design, AI/ML, Architecture, and GTM.
- Drive improvements to developer and integration experiences, considering both human developers and AI-driven consumers of platform capabilities.
Metrics & Impact
- Own success measures for initiatives, including ARR, adoption, retention, or TAM expansion.
- Evaluate strategic bets with a clear view of commercial and user impact.
- Communicate initiative outcomes to leadership and key stakeholders.
Cross-Functional Leadership
- Influence executives and peers across Product, Engineering, and GTM on strategic priorities.
- Serve as a role model IC, mentoring PMs and Senior PMs on discovery, strategy, and stakeholder management.
- Elevate product craft and organizational capability through best practices and thought leadership.
