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

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.
