Fullstack Developer New York, NY

Fullstack Developer Location: New York, NY Level: Senior Reports To: VP of Engineering Salary Range: $190k - $230k About Manifest 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. Backed by leading venture investors, Manifest OS is scaling rapidly. About The Team Our engineering team consists of 20+ senior-level engineers, and we're actively growing. You'll be joining a team of experienced professionals who value technical excellence and collaborative problem-solving. As a senior fullstack developer, you'll work alongside other seasoned engineers who bring deep expertise and a commitment to building exceptional products. What We're Looking For You need 7+ years of fullstack development experience with strong backend expertise in Node.js and TypeScript. You should have a proven track record of delivering complete features and products end-to-end that drive measurable business outcomes. Deep proficiency in modern JavaScript/TypeScript ecosystem and backend architecture patterns is essential. You must have experience building production-grade APIs with proper error handling, monitoring, and documentation, along with strong database design skills with PostgreSQL or similar relational databases. Hands‑on experience with cloud platforms (GCP preferred, AWS/Azure acceptable) is required. You should have extensive daily use of AI development tools — using Cursor, Copilot, or similar tools for 50%+ of your coding. Preferred qualifications include experience at AI-native companies like Cursor, Replit, Vercel, StackBlitz, Augment, or similar organizations. A track record building client portals, CRMs, or case management systems with complex permission models is valuable. Experience implementing AI workflows using LLMs for document processing, automation, or intelligent features is desired, along with Python knowledge for AI/ML integration and tooling. Familiarity with legal tech or heavily regulated industries and startup experience with comfort wearing multiple hats and driving initiatives independently would be beneficial. What You’ll Do We're seeking a backend-focused 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, GitHub Copilot, and v0 as extensions of their thinking. You'll be building our legal tech platform, 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. This For You If 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. Not For You If This role isn't the right fit if you prefer highly structured environments with detailed processes and clear guardrails at every step. You'll also want to look elsewhere if you struggle to maintain momentum in a fast-moving environment or need significant direction and oversight to stay productive. We need someone who can work autonomously and make thoughtful decisions without constant guidance.
