This is a remote, hourly contract role for experienced traders and market followers who want to help train AI systems on retail trading behavior and prediction markets. The work involves applying real market intuition to structured tasks such as estimating event probabilities, interpreting sentiment signals, and reviewing AI-generated market analysis.
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 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 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 remote, asynchronous role involves labeling and organizing statistical content, such as equations, datasets and problems, to build training data for AI systems. It also includes reviewing AI-generated statistics solutions, writing instructional material and testing models for reasoning errors and bias. It is aimed at people with strong probability and statistics backgrounds from research, teaching or applied work.
This is a remote hourly contract for a senior Rust engineer who will design and maintain high-performance data pipelines, annotation tooling, and evaluation systems used to train AI models. The work is production-focused, involves backend and tooling services, and suits engineers who can work independently with research and data teams.
This freelance remote contract asks threat intelligence and security professionals to help train and assess AI systems on cybersecurity topics. The work centers on checking adversary campaigns, attack chains and indicators of compromise, and on judging whether AI-generated security content is accurate and realistic.
This remote, task-based contract involves breaking video footage into individual shots and scenes and labeling them with camera angles, shot sizes, movement types, and on-screen actions. The work supports training of AI models that need to interpret visual media. It suits people with a sharp visual eye and a methodical approach who can work independently, and no prior video production or AI experience is required.
This remote freelance role asks you to film yourself doing everyday household tasks such as cooking, cleaning, and organizing, using an Android device and equipment supplied for the project. You will also check and correct the captions attached to your footage while following structured procedures. It suits people comfortable being recorded at home who can join scheduled sessions, and no prior AI or research background is needed.
This remote, flexible freelance role involves watching video clips, splitting them into individual shots, and labeling each shot with camera angle, framing, movement, and stylistic tone so AI systems can learn how footage is constructed. It suits visually trained creatives with a solid grasp of film grammar who can work independently and keep labeling consistent across large batches.
This remote contract role asks security practitioners to assess and improve AI systems on cybersecurity reasoning. The work centers on judging vulnerability scenarios, severity and remediation choices so the AI reflects how security teams actually operate. It suits people with hands-on vulnerability management experience who can explain security decisions clearly in writing.
This remote, task-based role asks scientists to check AI-generated material on wildlife and habitat conservation for accuracy and ecological soundness. Reviewers judge the quality of the reasoning behind proposed conservation strategies and give structured feedback so the AI describes these topics correctly. It suits experienced ecologists and wildlife specialists who can work independently on a flexible schedule.
This role evaluates how AI models handle audit procedures, internal controls, and assurance judgments by testing their reasoning, identifying gaps in professional skepticism, and writing correct audit approaches. It is for experienced auditors who can assess whether AI-generated evidence actually supports audit opinions.
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.
This role involves evaluating AI-generated responses about healthcare administration and operations, including billing, coding, insurance workflows, and compliance. You will write test prompts, review AI outputs for accuracy and feasibility, and provide correct guidance based on practical operational experience.
This is a remote contract role in which you review and correct bounding boxes that an AI model has produced on still drone and maritime sensor images, and you add labels for objects the model missed. It suits people with solid domain knowledge in aerial or maritime imagery who can follow detailed labeling guidelines, and it requires no prior AI experience.
