- Professional experience building, deploying, or fine-tuning ML models in a production environment.
- Expert proficiency in PyTorch or TensorFlow/Keras.
- Advanced Python skills including NumPy, Pandas, Scikit-learn, and experience with Hugging Face Transformers.
- Professional-level understanding of neural network architectures (Transformers, CNNs, RNNs) and optimization techniques.
- Hands-on experience with Prompt Engineering, RLHF, or RAG workflows.
- Ability to audit complex model logic, identify training data contamination, and evaluate mathematical proofs.
- Attention to detail in identifying model hallucinations, biases, or logical failures.
- Familiarity with cloud and MLOps tools such as AWS SageMaker, Google Cloud Vertex AI, Weights & Biases, or LangChain.
- Familiarity with vector databases like Pinecone, Milvus, or Weaviate.
Responsibilities
- Review AI-generated explanations of model architectures, loss functions, and backpropagation for technical accuracy.
- Validate ML-specific code including training loops, data preprocessing scripts, and model evaluations.
- Provide high-quality human feedback to refine RLHF frameworks to align models with intent, safety, and helpfulness.
- Critically assess how AI models navigate complex chain-of-thought (CoT) prompts and identify logical breakdowns.
- Conduct comparative testing between different model outputs based on specific technical taxonomies and performance metrics.
