About AI Training And Code Evaluation

AI training is the human side of building artificial intelligence. Technical contributors create, review, and evaluate examples that help AI models generate better code, reason through complex problems, and produce more accurate outputs.

In this project, your software engineering knowledge will support code generation workflows and model evaluation. Your analysis, coding tasks, annotations, and feedback will help assess how well AI systems handle realistic programming challenges.

• Contribute to next-generation AI systems through practical engineering work
• Use real-world coding problems to evaluate model performance
• Apply domain expertise rather than requiring prior AI experience
• Work remotely with flexible part-time scheduling

The Role

OpenTrain AI is seeking Research Engineers for a project focused on code generation and model evaluation. You will analyze and improve software across multiple programming languages, create and review coding tasks, and provide precise technical feedback that supports AI model training and assessment.

This is an intermediate-level contractor role for candidates with software engineering and AI code generation subject matter expertise. The work requires strong competitive programming and coding problem analysis skills, careful code validation, and the ability to explain technical decisions clearly in English.
