AI / ML Engineer - AI Trainer AfterQuery Experts Ann Arbor, MI Job Details Contract $115 - $135 an hour 5 hours ago Qualifications AI models GPU programming Software engineering GPU architecture Testing and evaluation System performance optimization Mid-level AI implementation Machine learning (ML) fundamentals Model evaluation Failure analysis Full Job Description AfterQuery is seeking AI / ML Engineer Experts to build and evaluate the model inference, GPU kernels, and ML systems performance scenarios that frontier AI labs use to test model judgment. In this remote, asynchronous role you will design realistic engineering problems, review how models reason through them, and give detailed feedback that makes the resulting training data trustworthy.

Why Apply Competitive Compensation:

$115-$135/hour, paid weekly

Innovative Impact:

Join a YC-backed research lab shaping how frontier models reason about software

Flexible Engagement:

Fully remote and asynchronous, on your own schedule Responsibilities Design challenging, realistic model inference, GPU kernels, and ML systems performance tasks drawn from production practice Evaluate model responses for correctness, sound reasoning, and subtle failure modes Document your reasoning clearly so another engineer can audit the judgement Required Qualifications Professional experience in ML engineering, inference optimization, or systems ML Familiarity with GPU execution, kernel-level performance, or serving stacks Ability to reason precisely about numerical and performance trade-offs About AfterQuery AfterQuery is a research lab investigating the boundaries of artificial intelligence through novel datasets and experimentation. We are backed by top investors, including Y Combinator and Box Group, and support all leading AI labs.
