Software Engineer - Ruby

What if your Ruby expertise could directly influence how AI writes, reviews, and reasons about production-grade software — for millions of developers around the world?

We're looking for experienced Ruby Software Engineers to help evaluate and improve AI-generated code, design realistic engineering scenarios, and contribute to the datasets that train the next generation of AI coding tools. Your real-world backend knowledge will shape how AI thinks about Ruby — from API design to system architecture.

This is a fully remote, flexible contract role built around your schedule. No AI background required — just strong Ruby skills and a sharp engineering mind.

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

What You'll Do

• Review and evaluate AI-generated Ruby code for correctness, performance, and maintainability
• Develop and refine backend services and APIs as part of realistic engineering tasks
• Identify bugs, edge cases, and architectural issues in AI-produced code and provide detailed, structured feedback
• Help create and validate technical datasets by working through real-world software engineering scenarios
• Collaborate asynchronously with researchers and engineers to support AI training and evaluation efforts
• Clearly articulate your technical reasoning and decision-making in written evaluations

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 design principles
• Naturally detail-oriented with an analytical, methodical approach to problem-solving
• Able to explain technical decisions clearly and concisely in writing
• No prior AI or machine learning experience required

Nice to Have

• Experience with Ruby on Rails or other Ruby-based frameworks
• Background in code review, technical writing, or engineering mentorship
• Familiarity with testing frameworks, CI/CD pipelines, or system design patterns
• Exposure to data engineering, ML infrastructure, or AI tooling

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 work
• Make a direct, tangible impact on how AI understands and writes Ruby code
• Potential for ongoing work and contract extension as new projects launch
