Software Engineer – Ruby (AI Training)
About The Role
What if your Ruby expertise could directly influence how AI writes and understands backend code for developers around the world? We're looking for experienced Ruby Software Engineers to work on real-world software systems that power data-driven and AI-supported workflows — reviewing, building, and evaluating production-grade code that helps train the next generation of AI models.
This is a fully remote, flexible contract role. Work asynchronously on your own schedule, take on as many hours as suits you, and make a tangible impact on how AI reasons about software engineering.
Organization: Alignerr
Type: Hourly Contract / Task-Based
Location: Remote
Commitment: 10–40 hours/week
What You'll Do
