About the Role

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
