We are seeking experienced Software Engineers to contribute to high-impact research collaborations with leading AI labs. 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.

Requirements

You 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 Responsibilities

• Review model-generated code trajectories on realistic software engineering tasks
• Reconstruct detailed reasoning steps that explain the solution process
• Annotate key decision points, debugging logic, and problem-solving strategies
• Analyze full task context, including codebases, issue descriptions, and test cases
• Ensure annotations reflect accurate, realistic developer reasoning and technical soundness
• Deliver structured, high-quality written explanations aligned with engineering best practices

Ideal Qualifications

• 2+ years of hands-on software engineering experience working with real-world codebases
• Bachelor’s degree in Computer Science, Software Engineering, or a related field (advanced degree preferred)
• Strong proficiency in Python, JavaScript, TypeScript, or similar commonly used open-source languages
• Familiarity with Git workflows, pull requests, and issue tracking systems
• Strong debugging and analytical skills
• Ability to clearly articulate technical reasoning in structured written form

Project Details

• Start Date: Immediate
• Duration: 1–2 months
• Commitment: Part-time (15–25 hours per week, with flexibility up to 40 hours per week)
• Fully remote with flexible scheduling

Application & Onboarding Process

• Submit your resume
• Participate in a short (approximately 15-minute) AI-based conversational interview to discuss your background and interest
• Receive follow-up communication within a few days regarding next steps and onboarding

Contract & Payment Terms

• Engagement will be structured as an independent contractor agreement
• Work can be completed remotely on your own schedule
• Projects may be extended, shortened, or concluded early based on performance and business needs
• Work assignments will not involve access to confidential or proprietary information from any employer, client, or institution
• Payments are processed weekly via Stripe or Wise based on services rendered
• Visa sponsorship is not available; H1-B and STEM OPT candidates cannot be supported at this time
