• Professional experience building, deploying, or fine-tuning ML models in production
• Strong command of neural network architectures such as Transformers, CNNs, and RNNs, plus modern optimization techniques
• Hands-on work with prompt engineering, RLHF, or retrieval-augmented generation pipelines
• Sharp analytical eye for spotting biased outputs, training data contamination, and faulty reasoning
• Located in the Baltimore area

Nice to have

• Expert proficiency in PyTorch or TensorFlow and Keras
• Advanced Python with NumPy, Pandas, and Scikit-learn, plus Hugging Face Transformers
• Exposure to cloud ML platforms such as AWS SageMaker or Google Cloud Vertex AI, or tools like Weights & Biases and LangChain
• Familiarity with vector databases including Pinecone, Milvus, or Weaviate

Benefits and work setup

• Compensation typically up to $80 per hour for qualifying tasks
• Fully remote with flexible, task-based scheduling
• One-hour focused sessions, with many assignments shorter in duration
