Senior Machine Learning Engineer

Job Summary

The Senior Engineer, R&D is responsible for developing, improving, and delivering machine learning models for DeepHealth clinical AI products. This hands-on role spans data, experimentation, model development, evaluation, and production delivery, working with machine learning peers, software engineers, clinicians, and product partners to investigate problems, make technical decisions, and deliver measurable improvements in model quality, robustness, and operational performance.

Essential Duties and Responsibilities 

• Improve existing production models through systematic error analysis, better data, targeted experiments, and changes to model architecture and training.

• Develop models for new products, taking problems from initial formulation and feasibility experiments through training, validation, and production integration.

• Partner with clinicians and product colleagues to define meaningful evaluation criteria, including sensitivity, specificity, and the clinical consequences of different error types.

• Evaluate robustness across patient populations, clinical sites, imaging equipment, and acquisition conditions; identify performance gaps and build evidence that improvements generalize.

• Improve data curation and annotation workflows, including coverage gaps, label quality, and prevention of data leakage.

• Build reproducible training and evaluation pipelines with traceable datasets, experiments, and model versions.

• Partner with software engineers to optimize inference speed, resource use, and operational reliability, and investigate model issues that emerge in production.

• Review relevant research, test promising approaches, and make evidence-based decisions about what to adopt.

• Contribute to validation and technical documentation with quality and regulatory colleagues.

• Review code and experiments, mentor colleagues, and communicate findings and trade-offs clearly.
