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.

• Role type: Contractor
• Work arrangement: Remote

• Write clear, actionable feedback and annotations for model training and assessment
• Collaborate with open-source contributors and technical stakeholders on technical direction
• Document technical decisions, best practices, and solutions
• Apply bug fixing, feature implementation, codebase refactoring, and performance optimization skills

Requirements And Qualifications

Candidates should bring substantial software engineering ability and experience analyzing coding problems. You must be comfortable working independently in a remote, collaborative environment and producing well-documented, consistent work under tight deadlines.

Expertise in at least one required programming language is expected, along with solid knowledge of algorithms and data structures. Open-source contributions or participation in collaborative software projects is also required.

• Expertise in competitive programming and coding problem analysis
• Expertise in at least one of Python3, Java, Rust, C++, Go, or TypeScript
• Solid knowledge of algorithms and data structures
• Proven open-source contributions or collaborative software project experience
• Strong analytical skills for interpreting constraints and comparing solution paths
• Exceptional written and verbal communication skills
• Meticulous attention to code validation and output consistency
• Ability to work independently in a remote environment
• Commitment to high-quality, well-documented code
• Comfort working in English
• Must be based in an eligible country listed in this posting
