[Hiring] Open-Source Engineer, Part-Time AI Code Work - Remote (India and United States)

OpenTrain AI is hiring for this role.

• $100–$150 per hour equivalent, paid per accepted task

• 100% remote

• Part-time

• About 15–20 hours a week, you choose when

Turn your open-source engineering judgment into paid work that helps improve coding systems.

AI-training work uses expert review to help coding systems improve. Engineers create realistic coding tasks, reproduce issues, implement fixes and tests, and evaluate AI-generated patches for correctness, security and maintainability. Open-source experience matters because contributors can navigate unfamiliar repositories and judge whether a change is safe and complete.

What you'll do

• Create difficult coding tasks from unfamiliar repositories, including realistic bug fixes and feature work

• Reproduce software issues by tracing execution through existing systems and identifying their causes

• Implement fixes and tests across unit, integration, regression and end-to-end levels

• Evaluate AI-generated patches for correctness, security, maintainability and completeness

Why this is worth your time

• $100–$150 per hour equivalent, paid per accepted task

• Apply open-source engineering judgment to difficult code, tests and clear model feedback.

• Work on AI coding systems as they are tested and improved, with no fixed shifts or commute

• Fully remote and flexible, no fixed shifts, no commute

Who this is for

• A verifiable GitHub presence showing substantial contributions to at least one open-source project

• Strong software engineering experience spanning application, platform, infrastructure or developer-tool work

• Professional fluency in English

• Work confidently across several programming languages, including Ruby, C#, C++, Rust, Go, Java, Python, JavaScript or TypeScript

• Your portfolio should include substantive code authorship; documentation, dependency, formatting or tiny-fix work alone does not qualify

• No AI experience needed.

Pay and details

• $100–$150 per hour equivalent; pay is per accepted task, as an independent contractor

• Part-time, about 15–20 hours a week; fully remote, India and United States
