This contract role asks security-minded people to probe AI systems built on the OpenClaw platform by running red-teaming exercises and writing adversarial prompts. The work suits cybersecurity practitioners who enjoy finding weaknesses and who can document their findings clearly for technical and non-technical readers.
This remote contract asks a physics expert to write advanced problems that test how well AI models reason, along with clear step-by-step solutions. The work also includes checking AI-generated answers for accuracy and quality of reasoning, and helping researchers refine benchmarks. It is aimed at people holding a master's degree in physics or a related field, and no prior AI experience is needed.
This contract role centers on designing and overseeing pipelines that merge genomic, clinical, and biomarker data into analytics platforms that support precision medicine. The work also helps shape how AI models learn to reason about healthcare data. It suits experienced professionals in healthcare data, genomics, or life sciences who want to contribute to AI development remotely.
This remote freelance role asks German-speaking voice professionals to record scripted and creative performances and to judge AI-generated German speech for naturalness and pronunciation. The recordings and feedback help train AI voice systems that will speak to German audiences. It suits experienced voice actors who work from a home studio and have a critical ear for delivery.
This role asks experienced revenue and sales operations professionals to design realistic problems that test AI agents on reconciling bookings, CRM, order, and communication data into one defensible answer. The work covers writing task prompts, scoring rubrics, and task environments, then solving and calibrating each task against AI models. It suits practitioners who know enterprise sales systems and can define checkable standards for a correct answer.
This remote contract role asks experienced Rust engineers to review and critique AI-generated systems code, focusing on memory safety, concurrency, and performance. The work also includes building tooling and backend services for large-scale data validation. It suits seasoned Rust developers who want flexible, task-based work on their own schedule.
This remote hourly contract asks experienced revenue operations and sales operations professionals to build realistic tasks that test AI agents on bookings, account reconciliation and fulfillment work. The author writes prompts and scoring rubrics, sets up task environments, then solves and calibrates each task against AI models. It suits people with hands-on enterprise B2B sales or revenue operations experience.
This contract role asks engineers to write and review step-by-step reasoning traces that show how a language model should plan, use tools, and reach decisions. The output becomes training data meant to make AI systems more reliable on complex, real-world tasks. It suits experienced machine learning engineers and researchers who can work remotely and on their own schedule.
This freelance role asks senior machine learning practitioners to write step-by-step reasoning traces that record how an expert plans, uses tools, and decides through hard technical problems, so that large language models learn to reason the same way. It suits people with deep ML or AI systems backgrounds who can explain their thinking clearly and work independently on open-ended tasks.
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 asks a senior software engineer to build and scale the backend infrastructure behind AI products, working closely with machine learning engineers and researchers. It suits experienced engineers who can work independently on production-grade services, data pipelines, and APIs.
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 role involves evaluating how well AI models can perform computational biology tasks. Computational biologists and bioinformaticians will design realistic analysis scenarios from their own work, run them through AI systems, and grade the results against professional standards to help benchmark model capabilities.
A drug discovery scientist will design realistic preclinical tasks and evaluate how well frontier AI models perform them, grading responses against professional standards. The role involves creating scenarios based on real workflows, running them through AI systems, and providing detailed feedback on whether the models correctly conduct SAR analysis, DMPK interpretation, screening triage, and other core discovery work.
This role involves designing realistic experimental biology tasks and evaluating how frontier AI models perform on benchmark scientific challenges. You'll create scenarios from your own laboratory practice, run them through AI systems, and grade the AI's output against professional standards to help train models on hands-on experimental work.
