- Help create and validate realistic software engineering scenarios used in AI training and evaluation datasets
- Assess AI-generated Ruby code for quality, accuracy, and production-readiness
- Collaborate asynchronously with researchers and engineers supporting cutting-edge AI development
- Complete task-based assignments independently on your own schedule
Who You Are
- 2+ years of professional software engineering experience
- Strong proficiency in Ruby and backend development — you're comfortable in production codebases
- Solid understanding of APIs, data-driven systems, and software engineering best practices
- Detail-oriented and analytical — you notice what's wrong and can articulate why
- Clear written communicator who can explain technical decisions without jargon
- Comfortable working independently in an async, remote environment
Nice to Have
- Experience with Ruby on Rails or other Ruby-based frameworks
