TL;DR · Principal AI and Data Sciences

Principal- AI and Data Sciences joins the MedTech sector to develop and validate machine learning prediction models within a regulated healthcare environment. The role involves designing, building, and maintaining end-to-end ML solutions on Databricks using both structured and unstructured data, including text and images. Key responsibilities include implementing ETL/ELT pipelines with Spark and PySpark, performing feature engineering, and developing supervised or unsupervised models using Python frameworks like Prophet, XGBoost, LightGBM, and Hugging Face. The position requires managing the model lifecycle through MLflow, conducting regression testing to detect performance drift, and ensuring interpretability for stakeholders. Technical requirements include proficiency in Databricks, Python, SQL Server, and React. The work focuses on solving complex medical technology problems by integrating structured and unstructured data models using agentic frameworks while adhering to strict regulatory constraints like HIPAA and GxP.

What you'll do

  • Design, build, and maintain end-to-end machine learning solutions on Databricks using structured and unstructured data.
  • Implement robust data pipelines and feature engineering using Spark, PySpark, and Delta Lake.
  • Develop, train, and optimize supervised and unsupervised models using Python frameworks like XGBoost, Prophet, and Hugging Face.
  • Establish model evaluation strategies and perform regression testing to detect performance drift across infrastructure changes.
  • Apply explainability techniques and produce model risk and performance reports for stakeholders and auditors.
  • Package, version, and register models using MLflow while supporting deployment through CI/CD pipelines and monitoring.
  • Troubleshoot production issues and investigate model failures to implement validated fixes with full traceability.
  • Integrate structured and unstructured data models using Agentic frameworks and APIs.

What we're looking for

  • 2–3 years of professional experience in an AI/ML or data science engineering role within the MedTech or regulated healthcare industry.
  • Proficiency in Databricks, including workspace use, notebooks, jobs, clusters, Delta Lake, and MLflow integration.
  • Proficiency in Python and common machine learning libraries such as Prophet, PySpark, XGBoost, LightGBM, and Hugging Face.
  • Experience building and evaluating prediction models for both structured (tabular) and unstructured data (text, images, signals).
  • Experience creating regression tests for models/pipelines and knowledge of unit and integration testing for ML components.
  • Proficiency in data engineering concepts including ETL/ELT, feature stores, SQL, and PySpark performance tuning.
  • Familiarity with model lifecycle tooling such as Git, CI/CD pipelines, Docker, and cloud services like Azure, AWS, or GCP.
  • Knowledge of MedTech regulatory considerations, including HIPAA compliance and documentation for verification and validation.
  • BS/MS in Computer Science, Data Science, Statistics, Biomedical Engineering, or a related field (preferred).
  • Experience with time-series forecasting, REACT programming, and deploying models in medical device environments (preferred).
