Senior Fullstack Developer (Remote from EU) - AI-Powered Legal Tech Platform
About the Role
We're seeking a backend-focused Senior Fullstack Developer who has mastered the art of building with AI. This isn't just another development role - we need someone who lives and breathes AI-augmented development, using tools like Cursor, Coderabbit, and v0 as extensions of their thinking. You'll be building our legal tech platform from the ground up, creating secure client portals and enterprise-grade systems that leverage AI at every level. If you've worked at companies like Replit, Vercel, or similar AI-native organizations, you'll understand exactly how we operate.
Manifest Law is a hyper-growth AI startup on its way to disrupt the legal industry and increase
access to justice for everyday Americans.
We empower lawyers to enter the 21st century by leveraging our cutting edge law-firm-in-a-box solution, unlocking a 10x boost in productivity, and 3x in lawyer earnings. This is also a game changer for customers who now have access to trusted, cheaper and faster legal representation.
We are one of the fastest-growing startups in New York (top 0.1% in growth speed) and are already EBITDA-positive.
Key Responsibilities
- Design and build scalable backend architectures for client/lawyer portals and B2B enterprise systems, with a focus on security, performance, and maintainability
- Deliver end-to-end business value by owning features from conception through deployment, ensuring each release directly impacts user success
- Implement AI-powered workflows including automated document generation, intelligent case evaluation, and conversational interfaces
- Create robust APIs and services using Node.js/TypeScript that power both internal tools and client-facing applications
- Build secure, compliant systems for handling sensitive legal documents, client data, and financial transactions
- Leverage AI development tools extensively to accelerate delivery - from code generation to automated testing to architecture decisions
- Collaborate with stakeholders to translate complex legal workflows into intuitive digital experiences
- Optimize development velocity by selecting and implementing the right tools, frameworks, and AI assistants for each task
What Sets You Apart
You don't just use AI tools - you think in AI-augmented workflows. While others debate whether AI will replace developers, you're already 10x more productive by treating AI as your pair programmer. You've likely contributed to or built tools that help other developers work with AI. You understand that the future of development isn't about memorizing syntax but about architecting solutions and guiding AI to implement them flawlessly. Your GitHub history shows not just code, but evidence of rapid iteration and AI-assisted development patterns.
