Frontend Software Engineer

One of our clients is hiring experienced Software Engineers 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.

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)

  • 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
