Senior AI Engineer (Remote) — RLHF & Model Audits

prolificacademicltd; USA; Remote; USD 91.000 - 129.000; Teilzeit

Benefits dieser Stelle

Fully remote

Up to $80/hour

Zusammenfassung

prolificacademicltd is seeking a senior contract AI/ML engineer to shape the next generation of large language models. You will work remotely on focused sessions up to one hour, contributing your production ML background on technically demanding tasks.

After a brief 10-15 minute skills assessment, researchers typically earn up to $80 per hour for specialist contributions. Candidates should have advanced degrees in CS/AI and hands-on experience with transformers, RLHF workflows, and ML auditing.

Qualifikationen

• BS, MS, or PhD in CS/AI/related quantitative field focused on ML.
• Production experience building, deploying, or fine-tuning ML models.
• Strong command of neural network architectures (Transformers, CNNs, RNNs) and optimization methods.
• Hands-on experience with prompt engineering, RAG pipelines, or RLHF workflows.
• Capacity to audit complex model logic, detect training-data contamination, and assess mathematical proofs behind ML algorithms.
• Meticulous attention to detail in catching hallucinations, biased outputs, or logical failures.

Aufgaben

• Evaluate AI-generated explanations of model architectures, loss functions, and backpropagation for technical soundness.
• Audit ML code and notebooks, including training loops, preprocessing scripts, and evaluation logic.
• Provide the structured human feedback that powers RLHF alignment with intent, safety, and helpfulness.
• Diagnose where AI reasoning breaks down on complex chain-of-thought prompts.
• Benchmark competing model outputs against predefined technical taxonomies and metrics.
