Backend Engineer, Part-Time AI Coding Task Authoring - Remote (United States)

Create backend coding tasks that test AI models on bug fixes, features, refactoring, and performance work. Pay is $50 to $100 per hour equivalent, paid per task that meets project specifications.

The work

You will create realistic backend coding problems used to train and evaluate AI systems. The work covers software bugs, new features, refactoring, and performance improvements.

You will also build reproducible environments, deterministic checks, and reference solutions so valid code is accepted and incorrect code is rejected. You will review technical submissions and explain your technical reasoning clearly.

• Create coding tasks for feature implementation, bug fixing, refactoring, and performance optimization.

• Build reproducible environments and deterministic verifiers for coding problems.

• Produce golden reference solutions for each task.

• Analyze complex defects and performance bottlenecks in large or legacy codebases.

• Implement scalable, maintainable features and document solution approaches for AI training data.

• Review technical submissions for accuracy and clarity.
