About The Role What if your deep software engineering expertise could directly shape how the next generation of AI writes code? We're looking for senior-level developers to evaluate, compare, and rank AI-generated code — helping AI systems learn what separates good code from great code. You'll review pairs of code solutions, assess them on correctness, efficiency, readability, and best practices, and provide the preference rankings that teach AI models to produce better software.

Your engineering judgment becomes the training signal that makes AI smarter. This is a fully remote, flexible contract role designed for experienced software engineers who want meaningful, intellectually engaging work on their own schedule.

Organization: Alignerr

Type: Hourly Contract

Location: Remote

Commitment: 10–40 hours/week What You'll Do Compare pairs of AI-generated code solutions and rank them based on quality, correctness, and engineering best practices

Evaluate code for functional accuracy — verifying that solutions produce correct outputs across standard and edge cases

Assess code quality factors including readability, efficiency, maintainability, and adherence to idiomatic patterns

Identify bugs, logic errors, security issues, and performance bottlenecks in AI-generated code

Write clear, structured justifications explaining your ranking decisions

Work across multiple programming languages and problem domains — from algorithms and data structures to systems design and API integrations





Complete task-based assignments independently on your own schedule Who You Are Senior-level software engineer with 5+ years of professional development experience

Proficient in at least two of the following: Python, JavaScript/TypeScript, Java, C++, Go, or Rust

Strong understanding of algorithms, data structures, and computational complexity

Experienced in code review — you can quickly spot issues and articulate what makes one solution better than another

Deep knowledge of software engineering best practices: clean code, design patterns, testing, and performance optimization

Clear written communicator who can explain technical reasoning concisely

Self-motivated and consistent when working independently without supervision Nice to Have Experience with machine learning, AI/ML pipelines, or training data curation

Background in competitive programming, technical interviewing, or algorithmic problem-solving

Familiarity with RLHF (Reinforcement Learning from Human Feedback) or preference-based AI training

Experience across both backend and frontend development

Contributions to open-source projects or technical mentoring experience

Knowledge of security best practices and common vulnerability patterns Why Join Us Work on cutting-edge AI projects alongside leading research labs

Fully remote and versátil — work when and where it suits you

Freelance autonomy with the structure of meaningful, task-based work

Your engineering expertise directly shapes how AI understands and generates code at scale

Intellectually stimulating work that keeps your skills sharp across languages and domains

Potential for ongoing work and contract extension as new projects launch
