Senior Manager, Data Science

BMS Digital Health is seeking a Senior Manager, Data Science to build and deliver hands-on, code-first analytics and algorithm development using wearable and sensor-derived longitudinal data . This role is for a data scientist who thrives in the details-owning work end-to-end from raw signals to validated outputs-spanning time-series QC, preprocessing, artifact handling, imputation, feature engineering, and modeling across accelerometry/actigraphy and cardio-respiratory signals (e.g., HRV, SpO ). The ideal candidate enjoys writing production-quality Python in orchestration environments, applying rigorous validation, and collaborating across internal and external partners.

This is a highly hands-on individual contributor role. You will spend a significant portion of your time coding, debugging, reviewing PRs, and building reproducible pipelines and models.

What You’ll Do (Hands-on Responsibilities)

• Build and maintain Python pipelines for wearable time-series data, including:
• QC, preprocessing, and sensor artifact removal
• Imputation (baseline through advanced methods) and feature engineering based on clinical concepts of interest
• EDA and signal characterization for accelerometry/actigraphy, HRV, and SpO
• Signal processing and signal detection
• Develop and validate models for longitudinal sensor data using:
• Frequency / time-frequency representations, digital filtering, and representation learning
• Quantitative characterization of physiological and clinically meaningful measures provably associated with disease progression or subtyping.
• Deep learning approaches (Transformers and/or ensembles) with model explainability techniques where appropriate
• Apply statistically rigorous approaches to repeated-measures data:
• Longitudinal statistical modeling (e.g., mixed effects / hierarchical models)
• Study-appropriate strategies for within-subject dynamics and missingness
• Implement strong evaluation practices and reproducible research standards:
• Nested CV, LOO, and/or OOB methods where appropriate
• Reproducible experimentation, documentation, and well-structured codebases
• Collaborate actively with internal stakeholders (clinical, stats, engineering, product) and external partners / third-party analytics providers, including QC and validation of vendor-derived outputs.
• Contribute to team excellence via code reviews, technical mentorship (scope depends on level), and raising engineering rigor., * Work at the intersection of digital biomarkers, machine learning, and clinical development
• Partner with multidisciplinary teams to advance analytics from real-world and trial-based wearable signals
• Build practical, validated solutions with high impact-and write the code that delivers them

We hire for skills and capabilities, not just credentials - if this role excites you, but doesn’t perfectly match your resume, we encourage you to apply anyway.
