Position Summary

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, SpO₂). 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 SpO₂

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.

Required Qualifications

PhD (preferred) or MS with strong experience in Data Science, Biostatistics, Biomedical Engineering, Computer Science, or related field.

PhD 3-5 years, MS 6-9 years, prior experience working on digital health initiatives within pharma industry, medical devices etc..

Demonstrated hands-on experience with time-series sensor data, including:

QC, preprocessing, artifact handling, imputation, feature engineering for accelerometry/actigraphy

Experience with HRV and/or SpO₂

Strong Python skills with evidence of shipping code:

Clean, testable code; object-oriented design; modular pipelines

Git/version control, code reviews, and collaborative development practices

Experience with longitudinal statistical modeling for repeated measures data.

Proven ability to translate analytical work into clear deliverables and communicate results to technical and non-technical stakeholders.

Preferred Qualifications (one or more of the following)

“Navigational physics” experience for movement data and/or biomechanical analysis (a plus): quaternions, Euler angles, dead-reckoning, orientation/heading estimation, etc.

Familiarity with sleep analytics and/or circadian cosinor modeling (or willingness to learn open-source libraries).

Experience managing or integrating third-party analytics (e.g., actigraphy QC workflows) and validating vendor outputs.

Experience with scalable compute and deployment patterns, including:

AWS experience; multi-GPU instances and parallelization for model training/inference

Why Join Us

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

If you come across a role that intrigues you but doesn’t perfectly line up with your resume, we encourage you to apply anyway. You could be one step away from work that will transform your life and career.

Uniquely Interesting Work, Life-changing Careers

With a single vision as inspiring as “Transforming patients’ lives through science™ ”, every BMS employee plays an integral role in work that goes far beyond ordinary.
