What they do
They join your team and work inside your lab’s tools, process, and timezone.
Your researcher writes and grades RLHF, SFT, and DPO data inside your lab. They follow your rubrics and tools.
Your researcher runs model evals, red teams weak points, and checks annotation quality for safety and alignment.
Your researcher builds RL environments and benchmarks for coding agents, reasoning, and domain work.
The search starts with 637,000 candidates. You meet the few who fit the field and the work.
Our database holds 637,000 candidates. Our pre-screened network has already cleared English, work history, and seniority. We narrow from there by field and the work your lab needs.
We screen 500+ candidates for each search across skills, English, communication, accent clarity, references, role fit, culture fit, and drive. You interview people who have already passed the bar.
Every placement clears our internal AI certification for prompt engineering and tool fluency. Then you interview the short list and test them the way your lab tests anyone.
One monthly rate covers placement, payroll, international compliance, and a lifetime replacement. You run the research inside your lab. We handle the rest.
