About the Role
Manifest is building a B2B attorney-facing product from the ground up, and this role owns it. You'll drive adoption of the Portal and Command Center — the core operating system for legal professionals — while monetizing a new product line. This is a 0→1 opportunity with direct commercial stakes and real user impact.
What You'll Do
Own the end-to-end attorney-facing product experience, including the Portal and Command Center
Build and ship AI-native features that read, analyze, and produce case-related work
Drive portal adoption by getting attorneys actively using the product
Translate user feedback into roadmap decisions and iterative product improvements
Collaborate daily with Ops, Sales, Engineering, and Legal to align on priorities
Define success metrics and own product performance against B2B revenue goals
What We're Looking For
Must-haves:
Bachelor’s degree or equivalent practical work experience.
0→1 product experience at a high-growth B2B company
Proven track record shipping AI-native products where AI is core to the experience
Deep fluency in AI and LLMs — understands how to build and ship with them
Strong cross-functional collaboration across Product, Engineering, Ops, Sales, and Legal
Commercial mindset: understands pricing, GTM, cost tradeoffs, and how to measure success
Nice-to-haves:
Experience with large-scale integrations or data modeling
Familiarity with AI evaluation systems
Technical fluency — coding not required, but comfort building with AI agents matters
This is for you if...
You've helped scale a B2B product from Series A to Series C and want to do it again. You thrive taking ambiguous problems from zero to a working product in users' hands. You want direct ownership over a commercial product with real revenue implications.
This is not for you if...
You prefer a defined roadmap over building one from scratch. You're not comfortable working closely with AI tools and systems as core product components. You need clear separation between PM work and commercial strategy
