Frontend TypeScript Engineer

Role overview

As a Frontend TypeScript Engineer (AI Training) at Alignerr, you will review, evaluate, and improve AI-generated TypeScript code. Your expertise will help AI models learn what truly type-safe, scalable, modern frontend development looks like in real-world frameworks.

Responsibilities

• Review AI-generated TypeScript for:
  • strict type safety
  • correct interfaces
  • proper use of generics and utility types
  • accurate async patterns and frontend system design
• Build complex, type-safe frontend components using 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, especially for complex type definitions and asynchronous patterns.
• Help AI models understand nuances of scalable, production-grade TypeScript across frontend frameworks.

Requirements

• Deep expertise in TypeScript (static typing, generics, interfaces, utility types).
• 3–5+ years of hands-on experience with modern frontend/full-stack frameworks such as React, Angular, Next.js, Nuxt.js, or Node.js.
• Strong written communication skills to explain complex technical decisions clearly.
• Detail-oriented, methodical, and focused on code quality.
• Comfortable working independently and asynchronously.
• Computer Science degree preferred (not required).

Nice to have

• 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 setup

• Fully remote, flexible contract.
• 10–40 hours/week (hourly contract).
