About the role

Role overview

As a TypeScript Developer (AI Training) at Alignerr, you will evaluate and critique AI-generated TypeScript code to ensure it meets real-world standards for type safety, scalability, and modern best practices. This is a fully remote, flexible hourly contract role (10–40 hours/week), where you won’t build a product—you’ll shape the quality of the intelligence behind code-generation tools.

Responsibilities

  • Review and evaluate AI-generated TypeScript for:
    • correctness
    • type safety
    • adherence to modern best practices
  • Solve complex problems using idiomatic TypeScript, including:
    • generics
    • utility types
    • modern frameworks
  • Provide detailed, structured feedback that explains architectural decisions and type logic clearly.
  • Identify weaknesses in AI-generated code (including subtle type errors and broader design flaws) and explain how to fix them.
  • Write clear technical summaries that connect strong type systems to how AI should learn.
  • Work independently and asynchronously on your own schedule.

Requirements

  • Deep expertise in TypeScript, including:
    • static typing
    • generics
    • interfaces
    • conditional types
    • utility types
  • 3–5 years of hands-on experience with modern frontend or full-stack frameworks such as React, Angular, Next.js, Node.js, or Nuxt.js.
  • Strong architectural instincts (not just “what works,” but “why”).
  • Excellent written communication skills for concise, clear technical explanations.
  • Self-directed and reliable while working without day-to-day oversight.
  • Bachelor’s degree or higher in Computer Science or related field (preferred).

Nice to have

  • Experience with data annotation, model evaluation, or AI training workflows
  • Familiarity with code review processes or technical documentation
  • Background in developer tooling, type system design, or compiler theory
  • Prior freelance/contract development experience

Commitment

  • 10–40 hours/week
  • Hourly contract, fully remote

Additional info

  • Ongoing impact on how AI understands and generates TypeScript code, with potential for contract extension.
