Job description

As a TypeScript Engineer, you will work remotely on an hourly paid basis reviewing AI-generated TypeScript code snippets, design proposals, and technical explanations, as well as generating your own high-quality content and reference solutions. You will evaluate step-by-step reasoning and problem-solving, checking solutions for correctness, clarity, and adherence to the prompt; identify errors in logic, type modeling, or architectural thinking; fact-check technical information; craft clear explanations and model solutions that demonstrate correct approaches; and rate and compare multiple AI responses based on their reasoning quality and implementation soundness.

Solid understanding of object-oriented programming (OOP), functional programming concepts, and common software design patterns.
Experience with Git and standard version control workflows (branching, merging, pull requests).
Familiarity with modern build tools (e.g., Webpack, Vite, Babel).
Minimum Bachelor’s degree in Computer Science or a closely related field.
Minimum C1 English proficiency (written and spoken), with strong ability to follow detailed technical guidelines.
Good to have : Merged PRs in TypeScript-based open-source projects.
