  • Ensure annotations are accurate, consistent, and aligned with defined quality and reasoning guidelines
  • Collaborate asynchronously with AI researchers and data teams to continuously improve dataset quality

Required Skills & Experience

  • 1–7 years of hands-on experience with Ruby on Rails in production environments
  • Strong knowledge of Ruby fundamentals and Rails conventions and architecture
  • Experience building RESTful APIs and backend services using Rails
  • Solid understanding of ActiveRecord, SQL databases, and schema design
  • Familiarity with testing frameworks such as RSpec and Minites
  • Strong analytical, reasoning, and written communication skills for producing high-quality annotations
  • Experience with system design, scalability, or security best practices is a plus.

Why Join Us?

  • Work on high-impact projects that contribute to building AI for Good.
  • Collaborate with top-tier engineers and domain experts from IITs, NITs, and BITS.
