Software Engineer - Ruby

Software Engineer – Ruby (AI Training)

About the Role

What if your Ruby skills 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 design, evaluate, and improve the real-world coding scenarios that teach AI systems how great backend engineering actually works.

This is a fully remote, flexible contract role. You'll bring your professional engineering experience to meaningful technical work — reviewing code, reasoning through system design, and helping shape AI that genuinely understands software at a production level.

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

What You'll Do

• Develop, review, and evaluate backend services and APIs written in Ruby and Ruby-based frameworks
• Analyze existing codebases for correctness, performance, and maintainability — and clearly explain your reasoning
• 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
• Background in code review, technical writing, or engineering mentorship
• Familiarity with AI tools or software evaluation workflows
• Exposure to data pipelines, machine learning systems, or AI-adjacent infrastructure

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 real-world code
• Potential for ongoing work and contract extension as new projects launch
