About The Position

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. 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.

Requirements

• Commercial mindset: understands pricing, GTM, cost tradeoffs, and how to measure success

Nice To Haves

• Technical fluency — coding not required, but comfort building with AI agents matters

Responsibilities

• 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
