This contract role centers on building and tuning high-performance Rust systems that power AI data pipelines, annotation tools, and model evaluation workflows. It suits senior engineers with at least five years of production Rust experience who care about performance, concurrency, and correctness in large-scale systems.
This is a remote, hourly contract role for senior software engineers who will help build, test and improve autonomous AI coding agents. The work centers on judging whether AI-written code is correct, efficient, secure and well designed, and on finding where these agents fail. It suits experienced engineers who can read unfamiliar codebases and explain clearly why code works or breaks.
This remote contract role involves designing and building the software that measures how well AI models perform, including evaluation pipelines, automated testing harnesses, and internal dashboards and APIs. It suits senior engineers who have shipped production systems and want to work closely with AI research teams on reliable, repeatable evaluation tooling.
This remote contract role involves building coding benchmarks and data pipelines that test how well frontier AI models reason about, debug, and write software. It is aimed at senior software engineers with several years of professional experience who can work across large, multi-language codebases.
This contract role is for senior engineers who build the backend systems behind AI model development. The work covers high-performance pipelines, annotation tooling, and evaluation infrastructure that support model training and benchmarking. It is aimed at engineers with several years of production experience in Go, Rust, Python, or C++ who are fully remote and available 20 to 40 hours per week.
This remote contract role asks you to judge posts, captions and comments written by AI, checking whether they sound natural, fit the culture of each platform and hold attention. It suits people who use social media actively and have a good instinct for what works online, with no marketing or content creation background needed.
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 remote contract role asks experienced software engineers to assess and rank code produced by AI models. The work involves judging correctness, efficiency and maintainability, then writing structured feedback that helps coding assistants learn what good code looks like. It suits developers who prefer flexible, independent, task-based work.
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 contract asks frontend engineers to review and improve JavaScript, HTML, and CSS code written by AI models, checking correctness, efficiency, and accessibility. It is fully remote and asynchronous, suited to developers who can explain their reasoning clearly in English.
This is a remote contract role building internal C tooling that supports data pipelines, annotation systems, and evaluation workflows for AI training. It is aimed at senior engineers with several years of production C experience who can also work across full-stack and interoperability tasks.
This contract role asks machine learning engineers to review and evaluate machine learning code generated by AI models, checking correctness, efficiency, scalability and clarity. Contractors also write their own ML solutions and explain modeling choices so that frontier AI systems improve at this work. It suits experienced ML practitioners who prefer fully remote, asynchronous, self-directed project work.
This remote contract role asks Ruby engineers to review, evaluate and improve backend coding scenarios that are used to train AI systems. It suits experienced developers who can judge code quality, explain their reasoning clearly and work independently on task-based assignments.
This remote, task-based contract involves designing realistic engineering challenges that evaluate advanced AI agents on enterprise work such as diagnosing failing integrations, tracing bugs, and writing fixes. It is aimed at working software engineers who debug real systems, write infrastructure and configuration code, and can verify their fixes in live or simulated environments.
This remote contract role involves running code written by AI, checking whether it behaves as intended, and recording bugs and quality issues in structured reports. It suits people who can read and run simple programs in at least one language and think logically, without needing a formal QA or computer science background.
This remote freelance role asks soil and water specialists to check AI-generated scenarios on erosion control, watershed management, and conservation planning. Reviewers flag flawed assumptions and outdated methods, then write structured feedback so the AI's answers become more accurate and practical. It is aimed at scientists with several years of hands-on experience who can work independently on task-based assignments.
This job asks native or heritage speakers of Peninsular Spanish to help train and check AI speech models. The work involves listening to generated audio, transcribing and labeling samples, and writing English feedback on accuracy and naturalness. It suits people with a trained ear for European Spanish who want flexible remote work and no prior AI experience.
This role consists of reviewing Spanish text produced by AI, including translations and original content, to judge its accuracy, naturalness and cultural fit for Spanish speakers. It is aimed at native or near-native Spanish speakers with a careful, methodical approach, and the work is done remotely on a flexible, task-based schedule. No prior AI or technology experience is required.
