In this role, you will help build high-quality training datasets that enhance AI models' reasoning and problem-solving capabilities on real-world software engineering tasks. This is a unique opportunity to apply your practical development experience to advance the next generation of intelligent systems.RequirementsYou will work on annotating frontier-model trajectories across SWE-bench-style tasks derived from real-world open-source repositories. Since many closed-source models do not expose internal reasoning traces, this project focuses on reconstructing and annotating the reasoning process behind model-generated solutions.Using your own problem-solving expertise and the full technical context of each task, you will infer and articulate the underlying chain-of-thought that explains how a solution is derived step by step.Key ResponsibilitiesReview model-generated code trajectories on realistic software engineering tasksReconstruct detailed reasoning steps that explain the solution processAnnotate key decision points, debugging logic, and problem-solving strategiesAnalyze full task context, including codebases, issue descriptions, and test casesEnsure annotations reflect accurate, realistic developer reasoning and technical soundnessDeliver structured,
