Fullstack Developer

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.

We're building an AI-powered legal tech platform and need a backend-focused fullstack developer who treats AI tools as a core part of how they build — not an afterthought. You'll own features end-to-end across secure client portals and enterprise-grade B2B systems, from architecture to deployment. This is a high-trust, high-autonomy role on a small team where your decisions directly shape the product.
