Software Engineer – Ruby (AI Training)

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
