FAQ

FAQs about Hiring for Agent Simulation

Quick answers to common questions about agent simulation projects and AI Trainer hiring on OpenTrain.

You can hire for any human-in-the-loop agent simulation task: scenario and task design, gold trajectory creation, rollout evaluation, step-level failure tagging, trajectory comparison, edge case writing, tool-use validation, and QA adjudication. Whether you need someone to write testable tasks with clear acceptance criteria or review thousands of rollouts for failure modes, you'll find specialists ready to start.

AI Trainers work inside whatever environment you use. WebArena, BrowserGym, OSWorld, AgentBench, custom sandboxes, internal tooling, or any other setup. You control access and credentials. We provide the talent, you provide the environment.

Every AI Trainer in our network completes a vetting process that includes identity verification, skills assessment, and domain screening. For agent simulation specifically, we look for experience with multi-step evaluation, rubric consistency, and the ability to identify subtle failure modes in agent behavior.

Most clients go from job post to first completed reviews within 72 hours. Timeline depends on your project scope, simulation environment, and onboarding requirements. For large or urgent projects, our managed service team can accelerate hiring and ramp-up.

You set the rates and pay AI Trainers directly. We add a small transparent fee on top. No hidden costs, no invoicing headaches. You can pay hourly, per task, or per rollout reviewed. All payments are handled through a single dashboard, regardless of where your team is located.

For large-scale or ongoing agent simulation projects, our managed service handles everything: recruiting, onboarding, QA, and project coordination. You get a dedicated team without the overhead of managing it yourself. Contact us for a custom quote.
