Frontend TypeScript Engineer

About The Role

What if your TypeScript expertise could directly shape how AI writes code for millions of developers around the world? We're looking for senior Frontend TypeScript Engineers to review, evaluate, and improve AI-generated TypeScript code — helping cutting-edge AI models understand what truly type-safe, scalable, and modern web development looks like.

This is a fully remote, flexible contract role built for experienced engineers who know TypeScript inside and out. You'll work alongside leading AI research teams to raise the bar on how AI understands and produces frontend code.

• Organization: Alignerr
• Type: Hourly Contract
• Location: Remote
• Commitment: 10–40 hours/week

• Review AI-generated TypeScript code for strict type safety, interface accuracy, correct use of generics, and utility types
• Develop complex, type-safe frontend components that demonstrate modern web architecture best practices
• Provide detailed technical analysis of architectural decisions and type-driven development strategies
• Identify and flag ambiguities or errors in AI responses related to complex type definitions, asynchronous patterns, and frontend system design
• Help AI models understand the nuances of scalable, production-grade TypeScript across real-world frameworks

• Deep expertise in TypeScript — you live and breathe static typing, generics, interfaces, and utility types
• 3–5+ years of hands-on experience with modern frontend or full-stack frameworks such as React, Angular, Next.js, Nuxt.js, or Node.js
• Strong written communication skills — you can explain complex technical decisions clearly and concisely
• Detail-oriented and methodical, with high standards for code quality
• Comfortable working independently and asynchronously on your own schedule
• A degree in Computer Science or a related field is preferred, but not required if your skills speak for themselves

• Experience with data annotation, model evaluation, or AI training workflows
• Familiarity with code review processes and technical documentation
• Background in software architecture, design patterns, or developer tooling

• Work on frontier AI projects alongside the world's leading research labs
• Fully remote and async — work when and where it suits you
• Freelance autonomy with meaningful, technically challenging work
• Make a direct, lasting impact on how AI understands and generates TypeScript code
• Potential for ongoing work and contract extension as new projects launch
