Job Description
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
