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
