Overview
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 based in the London area to evaluate, compare, and rank AI-generated code — helping AI systems learn what separates good code from great code.
This is a fully remote, flexible contract role designed for experienced software engineers who want meaningful, intellectually engaging work on their own schedule.
Responsibilities
* Review pairs of AI-generated code solutions and rank them based on quality, correctness, and engineering best practices
* Evaluate code for functional accuracy — verify 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 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
Engagement & Location
