Job Description

Role: Frontend Software Engineer

Keystone Recruitment is seeking experienced Frontend Software Engineers to join a high-impact project. This remote role involves collaborating with leading AI labs to build high-quality training datasets, directly improving AI model performance on real-world client-side web development tasks. This is a unique chance to apply your expertise to shape the next generation of intelligent systems.

About the Project

You will be instrumental in creating high-quality "vibe coding" datasets. These datasets are specifically designed to train AI models on essential client-side web development skills, encompassing 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 thoroughly 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 a 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 strong focus on verifiability and precision.

Project Details

  • Start Date: Immediate
  • Duration: 1–2 months (may be extended, shortened, or concluded based on performance and project needs)
  • Commitment: Part-time (15–25 hours/week, with flexibility up to 40 hours/week)
  • Work Arrangement: Fully remote and asynchronous

Compensation & Contract Terms

  • Rate: $70–$80 per hour, based on experience
  • Payments: Weekly via supported payment platforms
  • Classification: Independent contractor
  • Note: No access to confidential or proprietary information from any employer, client, or institution.

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.
