Node.js Developer for AI Model Training

Apply your Node.js expertise to help train next-generation AI systems by shaping high-quality technical inputs, code reviews, and documentation that teach models how to reason and perform in real-world backend scenarios. No prior AI experience is required, your domain and engineering knowledge are the value. micro1 is an AI data lab that converts expert domain knowledge from fields such as finance, healthcare, and engineering into training data, evaluations, and feedback loops to improve frontier models and AI agents.

• Provide expert-level input and feedback using Node.js, JavaScript, and TypeScript to support model training and evaluation.
• Analyze and review code samples for correctness, efficiency, maintainability, and best practices.
• Collaborate with multidisciplinary teams to identify common backend development patterns and problem-solving strategies.
• Evaluate real-world Node.js scenarios to help models learn robust, scalable, and maintainable solutions.
• Document technical insights, edge cases, and nuanced considerations in clear written form.
• Translate complex technical concepts so they are accessible to both technical and non-technical stakeholders.
• Maintain high standards of written and verbal communication with internal and external partners.

• Extensive hands-on professional experience with Node.js, JavaScript, and TypeScript.
• Expert problem-solving and debugging skills in distributed application systems.
• Strong attention to detail in code review and written documentation.
