Customertimes is a global digital engineering, product development, and technology consulting company. Headquartered in New York, we have a team of 1300+ experts and offices in 12 countries.

Requirements:‍

• Strong proficiency in Python;

• 3+ years of relevant working experience in a technical capacity, with a focus on ML. Prior experience with LLMs is strongly preferred;

• Familiarity with LLM-based prompt engineering and text processing workflows;

• Basic familiarity with Spark, Databricks, and MLFlow environments (for interacting with infrastructure, not deep configuration);

• Experience working in AWS environments;

• Comfort with object-oriented programming concepts (e.g., using/extending classes, Pydantic models);

• Experience working with Anthropic models (preferred) or other major LLMs (OpenAI, LLAMA, etc.);

• Familiarity with RAG (Retrieval Augmented Generation) concepts (not core but potentially useful in the future);

• Basic exposure to classical NLP (e.g., LSTM architectures, non-LLM text processing);

• Healthcare or clinical text processing experience is a strong plus, but not required;

• Understanding of model evaluation metrics (classification, regression) and statistical validation basics.

Responsibilities: ‍

• Process electronic medical record documents into a form suitable for LLMs;
• Design and craft effective prompts for information extraction;

• Evaluate LLM performance against human-labeled ground truth;

• Collaborate with clinicians, epidemiologists, and statisticians to align extracted data with clinical meaning;

• Troubleshoot and iterate extraction pipelines;

• Integrate with internal ML infrastructure and production environments.
