Software Engineer – Ruby (AI Training)

About The Role

What if your Ruby expertise could directly influence how AI understands and writes production-grade software for developers around the world? We're looking for experienced Ruby Software Engineers to help evaluate, refine, and build the technical datasets that shape the next generation of AI coding tools.

This is a fully remote, flexible contract role. You'll work asynchronously — on your own schedule — contributing deep engineering knowledge to real-world AI training and evaluation projects.

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

What You'll Do

• Develop and maintain backend services and APIs using Ruby and Ruby-based frameworks
• Review and analyze AI-generated Ruby code for correctness, performance, and maintainability
• Evaluate realistic software engineering scenarios and provide structured, expert-level feedback
• Help create and validate technical datasets used in AI training and evaluation workflows
• Collaborate asynchronously with researchers and engineers to improve how AI reasons about code
• Identify bugs, edge cases, and suboptimal patterns in AI-produced codebases

Who You Are

• 2+ years of professional software engineering experience
• Strong proficiency in Ruby and backend development — you’re comfortable in production environments
• Solid understanding of APIs, data-driven systems, and software architecture principles
• Detail-oriented and analytical — you can clearly explain why code works or doesn't
• Self-directed and reliable when working independently without hand-holding
• Able to articulate technical decisions in writing with precision and clarity

Nice to Have

• Experience with Ruby on Rails or other Ruby-based frameworks
• Familiarity with AI tools, code evaluation workflows, or technical dataset creation
• Background in code review, engineering mentorship, or technical writing
• Exposure to testing frameworks, CI/CD pipelines, or software quality processes

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 generates Ruby code
• Potential for ongoing work and contract extension as new projects launch
