FrontEnd Software Engineer at Keystone Recruitment

Keystone Recruitment is seeking an experienced FrontEnd Software Engineer to support high-impact research collaborations with leading AI labs. This 100% remote role involves building high-quality training datasets to improve AI model performance on 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 be creating 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 involve:

• 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 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 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)

Application & Onboarding Process

• Submit your resume.
• Complete a short AI-led interview (approximately 15 minutes).
