FrontEnd Software Engineer

Role: FrontEnd Software Engineer

One of Keystone Recruitment's clients is seeking experienced FrontEnd Software Engineers to contribute to high-impact research collaborations with leading AI labs. In this critical role, you will be instrumental in building high-quality training datasets that significantly enhance AI model performance on real-world client-side web development tasks.

This presents a unique opportunity to leverage your front-end engineering expertise to directly influence and shape the next generation of intelligent systems.

About the Project

You will be responsible for creating high-quality “vibe coding” datasets. These datasets are specifically designed to train AI models on essential client-side web development skills, including state management, user interactivity, UI correctness, and overall robustness.

Projects you may work on 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 applications, games, and simulations.
• Develop precise, binary rubrics, clearly tagged by verification type.
• Ensure all rubric criteria are strictly pass/fail and verifiable through both screenshot analysis and code inspection.
• Design tasks specifically crafted to 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 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.
• Proven ability to write clear technical specifications and structured evaluation criteria.
• A detail-oriented mindset with a strong focus on verifiability and precision.

Project Details

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

Application & Onboarding Process

The application process involves:

• Submitting your resume.
• Completing a brief AI-led interview (approximately 15 minutes).
• Receiving follow-up communication within a few days regarding next steps and onboarding details.

Compensation & Contract Terms

• Hourly Rate: $70–$80 per hour, commensurate with experience.
• Payments: Weekly, via supported payment platforms.
• Classification: Independent contractor.
• Contract Flexibility: Project duration is subject to extension, shortening, or conclusion based on performance and project needs.
• Confidentiality: No access to confidential or proprietary information from any other employer, client, or institution is required.
