Software Engineer - Ruby

Software Engineer – Ruby (AI Training)

About The Role

What if your Ruby skills could directly influence how AI understands and generates real-world software? We're looking for experienced Ruby Software Engineers to work on production-grade systems and help shape the technical datasets that train the next generation of AI coding tools.

This is a fully remote, flexible contract role built for engineers who love clean code, thoughtful architecture, and meaningful work. No AI background required — just strong Ruby chops and a sharp engineering mind.

• Organization: Alignerr
• Type: Hourly Contract / Task-based
• Location: Remote
• Commitment: 10–40 hours/week

What You'll Do

• Design, build, and maintain backend services and APIs using Ruby and Ruby-based frameworks
• Review and analyze real-world codebases for correctness, performance, and maintainability
• Evaluate realistic software engineering scenarios and help create high-quality technical datasets
• Validate and refine AI-generated Ruby code — identifying bugs, edge cases, and architectural weaknesses
• Collaborate asynchronously with researchers and engineers supporting AI training and evaluation efforts
• Work independently on task-based assignments, fully on your own schedule

Who You Are

• 2+ years of professional software engineering experience
• Strong proficiency in Ruby and core backend development concepts
• Comfortable reasoning about production codebases, REST APIs, and data-driven systems
• Detail-oriented and analytical — you can clearly explain the why behind technical decisions
• Self-motivated and reliable when working independently without close supervision

Nice to Have

• Experience with Ruby on Rails or other Ruby-based frameworks
• Familiarity with testing frameworks such as RSpec or Minitest
• Background in code review, technical writing, or engineering mentorship
• Exposure to AI tools or software evaluation workflows
• Experience working with distributed or asynchronous teams

Why Join Us

• Work on cutting-edge AI projects alongside leading research labs
• Fully remote and flexible — work when and where it suits you
• Freelance autonomy with the structure of meaningful, task-based engineering work
• Make a direct, tangible impact on how AI understands and writes real-world Ruby code
• Potential for ongoing work and contract extension as new projects launch
