ABOUT MANIFEST
Manifest OS is the leading AI-native company on a mission to replace the billable hour and make legal services more accessible for American businesses and consumers. We power the next generation of AI-native law firms with one unified global brand, a proprietary technology platform, and a centralized back office, enabling lawyers to eliminate the administrative burden and focus on delivering exceptional outcomes for their clients. Manifest OS has raised a $60M Series A from Menlo Ventures, Kleiner Perkins, First Round, and Quiet Capital.
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:
- 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
