Manifest OS is an 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 looking for a backend-leaning Software Engineer to help build the legal tech platform powering the next generation of AI-native law firms. You'll own the development of secure client portals and enterprise-grade systems — from architecture to production.
Build and ship full-stack features end-to-end across our legal tech platform
Design and maintain production-grade APIs with proper error handling and documentation
Architect secure client portals and case management systems with complex permissions
Integrate LLMs and AI workflows into document processing and automation features
Contribute to database design and backend architecture using PostgreSQL
Deploy and manage services on cloud infrastructure, preferably GCP
Must-haves:
10+ years of fullstack development with strong Node.js and TypeScript expertise
Proven track record delivering features that produce measurable business outcomes
Experience building production APIs with monitoring, error handling, and documentation
Strong PostgreSQL or relational database design skills
Hands-on cloud platform experience — GCP preferred, AWS or Azure acceptable
Daily use of AI coding tools (Cursor, Copilot, or similar) for 50%+ of your workflow
Nice-to-haves:
Experience at AI-native companies such as Cursor, Replit, Vercel, or similar
Background building client portals, CRMs, or case management systems
Python knowledge for AI/ML tooling and integration
Familiarity with legal tech or other regulated industries
You treat AI tools as core to how you architect and ship software. You want to build infrastructure that makes legal services more accessible to people. You thrive with ownership and prefer outcomes over process
You need detailed processes and defined guardrails to do your best work. You prefer significant direction and oversight over autonomous decision-making. You're earlier in your career with AI-augmented development workflows.
