At Edwards Lifesciences, the Implantable Heart Failure Management (IHFM) AI, Product and Platforms organization designs and builds the software and data products that clinicians and patients depend on. As a Senior Data Scientist, you own modeling for a clinical or product domain, drive problem framing with product and clinical partners, own offline-validation rigor, and author model documentation that meets FDA submission expectations for regulated products.

Based in Irvine, CA, you'll join a high-impact medtech innovation hub in the heart of Orange County, collaborating in person with cross-functional teams to shape patient-focused technology.

• Domain modeling. Own modeling for a clinical or product domain, for example, arrhythmia classification, cardiac imaging segmentation, clinical prediction, or patient outcome forecasting, from framing through offline validation.

• Architecture selection. Select and adapt architectures for the modality (vision transformers or encoder-decoder networks for imaging, transformers, or temporal models for signals) and apply self-supervised and representation learning under limited labels.

• Statistical depth. Apply survival analysis, Bayesian modeling, and causal inference where the clinical question requires (statsmodels, lifelines or scikit-survival, PyMC).

• Evaluation & subgroup. Design offline evaluation, calibration, and clinical performance validation strategies, including subgroup and bias analysis across sex, age, and device cohort, with Medical Affairs and Clinical Science.

• Interpretability & documentation. Author submission-grade model documentation including calibration, uncertainty, and interpretability evidence (SHAP, Captum), and improve the team's modeling and validation practice.

• Research adoption. Evaluate and adapt current AI/ML for health research to IHFM problems, and mentor less experienced data scientists.

• Handoff. Coordinate the handoff of offline-validated custom models to AI/ML Engineers (Applied), and partner with Regulatory Affairs on submission strategy.

• Algorithm development, analysis & reporting. Create, test, and improve complex algorithms, NLP, and machine learning models; analyze results; develop insights; and produce reports and dashboards to communicate performance and findings to stakeholders.

• Data preparation & quality. Process, cleanse, label, and verify structured and unstructured data used for analysis; collaborate with internal teams and external partners on data standards, metrics, analytics, and reporting.

• Tools, integration & design controls. Identify and integrate data sources, software, and analytics tools (e.g., Python, SQL, SAS, Power BI, Tableau Prep); support development of design control documentation including algorithm requirements and risk documentation.

• Bachelor's in related field (e.g., Computer Science, Engineering, Biostatistics or Scientific) plus 4 years -or- Master's plus 3 years of previous experience including industry or industry/ education

• Relocation is not provided for this role. Only candidates within a 50-mile radius of Irvine, California will be considered.

• Depth in at least one data modality relevant to IHFM, for example, time-series, or medical imaging (echocardiography, cardiac magnetic resonance imaging, or computed tomography).

• Command of the relevant architecture families and of transfer and self-supervised learning.

• Strong Python and SQL, and depth in modeling and experiment tracking such as PyTorch, TensorFlow, and MLflow.

• Command of evaluation, calibration, and clinical performance methodology, including subgroup analysis, and the ability to author documentation suitable for regulatory submission.

• A track record of owning modeling for a domain and communicating results to clinical, product, and regulatory partners.

• Experience with clinical validation, retrospective clinical data, or regulated medical software (SaMD).

• Depth in time-series or medical imaging modeling, including segmentation and registration, for example, MONAI, pydicom, or SimpleITK.

• Bayesian modeling, causal inference (DoWhy, EconML), or survival analysis (lifelines, scikit-survival).

• Generative approaches for augmentation or synthetic data (autoencoders, GANs, or diffusion models).

• Exposure to multimodal modeling, combining signals, imaging, labs, and notes into patient-state models.

• Familiarity with R, JAX, or hyperparameter optimization (Optuna, Ray Tune).

• Contributions to internal or external research (publications, patents, or venues such as MICCAI or ML4H).

Aligning our overall business objectives with performance, we offer competitive salaries, performance-based incentives, and a wide variety of benefits programs to address the diverse individual needs of our employees and their families.

For California (CA), the base pay range for this position is $108,000 to $153,000 (highly experienced).
