We're looking for experienced Frontend TypeScript Engineers in the New York area to review, evaluate, and guide AI-generated code — helping cutting-edge AI models understand what truly type-safe, scalable, and modern web development looks like.
What if your deep expertise in TypeScript could directly influence how AI writes code for millions of developers around the world?
This is a fully remote, flexible contract role. You'll work alongside leading AI research teams, applying your real-world frontend knowledge to tasks that have a lasting impact on how AI understands and produces TypeScript code.
Why Join Us
Work on cutting-edge AI projects alongside leading research labs.
Fully remote and flexible — work when and where it suits you.
Freelance autonomy with the structure of meaningful, task-based work.
Make a direct, tangible impact on how AI understands and writes modern TypeScript.
Potential for ongoing work and contract extension as new projects launch.
Responsibilities
Review AI-generated TypeScript code for strict type safety, accurate interface design, and correct generic usage.
Develop complex, type-safe frontend components that demonstrate best practices in modern web architecture.
Provide detailed technical commentary on architectural decisions and type-driven development strategies.
Identify and flag ambiguities or errors in AI responses related to complex type definitions and asynchronous frontend patterns.
Work independently and asynchronously — fully on your own schedule.

Deep expertise in TypeScript — including static typing, generics, interfaces, and utility types.
Strong written and verbal communicator who can clearly articulate technical reasoning.
Naturally detail-oriented with a high standard for code quality and correctness.
Preferred skills
Experience with data annotation, model evaluation, or AI training workflows.
Familiarity with full-stack TypeScript patterns and performance optimization.
Background in code review, technical writing, or engineering mentorship.
