  • Visualizations and simulations
  • Front-end tools and utilities

Key Responsibilities

  • Write realistic, self-contained prompts for various client-side web applications, games, and simulations.
  • Develop precise, binary rubrics, carefully tagged by verification type.
  • Ensure all rubric criteria are strictly pass/fail and fully verifiable through screenshots and code inspection.
  • Design tasks that rigorously test UI behavior, logic correctness, and edge-case handling.

Ideal Qualifications

  • 2+ years of experience in front-end or full-stack development, or equivalent technical content creation experience in web development.
  • A Bachelor’s degree in Computer Science, Software Engineering, or a related field is required, with an advanced degree preferred.
  • Strong proficiency in core web technologies including JavaScript, TypeScript, React, or vanilla JavaScript.
  • Demonstrated ability to write clear technical specifications and structured evaluation criteria.
  • A detail-oriented mindset, with a strong emphasis on verifiability and precision in all tasks.

  • Start Date: Immediate
  • Duration: 1–2 months (with potential for extension)
  • Commitment: Part-time (15–25 hours/week, flexible up to 40 hours/week)
  • Fully remote and asynchronous work environment.

Application & Onboarding Process

  • Submit your comprehensive resume.
  • Complete a brief AI-led interview (approximately 15 minutes).
  • Receive follow-up communication within a few days regarding next steps and onboarding details.

Compensation & Contract Terms

  • $70–$80 per hour, commensurate with experience.
  • Weekly payments processed via supported payment platforms.
  • Independent contractor classification.
  • Project duration is subject to extension, shortening, or conclusion based on performance and evolving project needs.
