Role Overview

One of our clients is hiring experienced FrontEnd Software Engineer to support high-impact research collaborations with leading AI labs. In this role, you will help build high-quality training datasets that improve AI model performance on real-world client-side web development tasks. This is a unique opportunity to apply your front-end engineering expertise to shape the next generation of intelligent systems.

About the Project

You will create high-quality “vibe coding” datasets designed to train models on client-side web development skills — including state management, interactivity, UI correctness, and robustness.

Projects may include:

  • Interactive web applications
  • Browser-based games
  • Visualizations and simulations
  • Front-end tools and utilities

Key Responsibilities

  • Write realistic, self-contained prompts for client-side web apps, games, and simulations
  • Develop precise, binary rubrics tagged by verification type
  • Ensure rubric criteria are strictly pass/fail and verifiable via screenshot and code inspection
  • Design tasks that test UI behavior, logic correctness, and edge-case handling

Ideal Qualifications

  • 2+ years of experience in front-end or full-stack development (or technical content creation in web development)
  • Bachelor’s degree in Computer Science, Software Engineering, or related field (advanced degree preferred)
  • Strong proficiency in JavaScript, TypeScript, React, or vanilla JavaScript
  • Ability to write clear technical specifications and structured evaluation criteria
  • Detail-oriented mindset with a focus on verifiability and precision

Project Details

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

Application & Onboarding Process

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

Compensation & Contract Terms

  • $70–$80 per hour, based on experience
  • Weekly payments via supported payment platforms
  • Independent contractor classification
  • Project duration may be extended, shortened, or concluded based on performance and project needs
  • No access to confidential or proprietary information from any employer, client, or institution
