This role involves evaluating and reviewing code generated by AI systems across multiple programming languages, identifying bugs, logical errors, and inefficiencies. The position is designed for individuals with coding knowledge who can assess code quality and provide constructive feedback to improve AI-generated outputs, regardless of formal background.
Review and evaluate AI-generated Java code for correctness and efficiency, and write high-quality Java solutions to coding problems at varying difficulty levels. This role is ideal for Java developers who can also provide clear explanations of code logic and problem-solving strategies to support AI model training.
This role involves writing, debugging, and evaluating AI-generated code to help train and improve AI coding assistants. Software engineers will review code quality, identify bugs and security issues, provide detailed feedback, and design test scenarios to stress-test AI capabilities across various programming languages and frameworks.
This role involves designing, building, and scaling infrastructure systems that power AI products and services. Senior software engineers will work on production-grade systems supporting AI training, evaluation, and deployment pipelines, writing clean and performant code while collaborating with ML engineers and researchers in a remote, autonomous environment.
This remote contract role asks experienced TypeScript developers to review and critique AI-generated frontend code for type safety, interface accuracy, and architecture. The work also includes building reference components and explaining type-driven design choices so that AI models can learn from expert reasoning. It suits independent developers with several years of hands-on frontend experience who work well without supervision.
This remote contract role asks experienced TypeScript frontend developers to review and assess code written by AI models, and to show those models what type-safe, modern web development looks like. It suits engineers who can explain architectural and typing decisions clearly and who prefer to work on their own schedule on task-based assignments.
This remote contract role asks experienced full-stack developers to review and evaluate code and system designs produced by AI models. The work also includes building tooling for data annotation and quality control, done asynchronously on a flexible schedule. It suits engineers with several years of production experience who can give precise technical feedback.
This remote contract role asks senior full-stack engineers to assess AI-generated code across frontend and backend, judging correctness, quality, and security. It also involves building internal tooling for data annotation and reviewing system designs. It suits experienced engineers who can give precise written feedback that helps AI models write better code.
This contract role asks software engineers to write, review and evaluate code produced by AI systems, giving expert feedback that helps coding assistants become more accurate, secure and reliable. It suits independent developers who can read code closely, explain their technical reasoning in plain writing, and work asynchronously on their own schedule.
This remote contract role centers on designing, building and scaling the backend systems, APIs and data pipelines that support AI model training, evaluation and deployment. It suits experienced software engineers who can work autonomously on production-grade systems and collaborate asynchronously with ML researchers and product managers.
This contract role asks engineers to write, debug and review code, then judge code produced by AI models so that those models learn to reason about software like experienced developers. It suits software engineers who write clean code, explain their technical choices clearly in writing, and work independently on their own schedule.
This remote contract role asks a senior engineer to design, build and scale the backend systems behind AI products, including training, evaluation and deployment pipelines. It suits experienced software engineers who enjoy hard architectural problems and want to work asynchronously alongside ML researchers and product managers.
This contract role centers on designing, building and scaling production software that supports AI training, evaluation and deployment pipelines. It suits experienced backend engineers who can architect reliable systems, debug distributed infrastructure and work independently in an asynchronous, remote team.
This freelance role asks you to write code and to evaluate code produced by AI models, helping make AI coding assistants more accurate and reliable. You will review AI outputs for correctness, efficiency, and security, then explain your judgments in clear written feedback. It suits experienced programmers who can work independently on a flexible, remote schedule.
This contract role asks you to review code produced by AI models and to write backend solutions yourself, covering server-side logic and API design at several difficulty levels. It suits backend engineers who can judge code on correctness, efficiency and clarity and explain their reasoning in clear English. The work is fully remote and asynchronous, with a minimum of 15 hours per week.
This remote contract role asks senior TypeScript developers to review AI-generated code for type safety, scalability and modern practices. The work centers on writing structured feedback that helps AI models understand architectural choices and type logic. It is aimed at experienced developers who can work independently on flexible hourly commitments.
This contract role asks an experienced mobile engineer to design realistic coding challenges that test how well AI models handle mobile software problems such as bug fixing, feature building, refactoring and performance work. For each challenge the expert builds a reproducible environment, writes verifiers that accept varied correct solutions and reject shortcuts, and provides a reference solution. It suits developers with deep hands-on experience in React Native, Flutter, SwiftUI, UIKit, Jetpack Compose or Android Views.
