Machine Learning Engineer (Model Dev)

This position is listed on behalf of a partner company, who manages all applications and next steps. Our partner is looking for a Machine Learning Engineer (Model Dev) based in United States. This role offers the opportunity to develop machine-learning solutions with direct impact on cancer care and clinical decision-making. You will work across the full model-development lifecycle, from research and experimentation through validation and production deployment. The position focuses on multimodal clinical and pathology data, including whole-slide images, molecular information, and longitudinal patient data. You will collaborate closely with ML scientists, engineers, clinicians, biostatisticians, product teams, and regulatory partners. A key focus will be improving model robustness, interpretability, reproducibility, and performance across diverse clinical environments. You will also contribute to foundation-model development, scientific research, publications, and the advancement of medical AI. This is an opportunity to combine strong engineering skills with meaningful scientific and healthcare impact. Accountabilities - Develop and evaluate AI-based biomarkers using multimodal datasets, including whole-slide images, clinical variables, and molecular data, to predict patient outcomes, treatment benefit, and molecular characteristics. - Contribute to self-supervised foundation models and downstream machine-learning systems, including multiple-instance learning, survival and hazard models, segmentation, and classification. - Design and evaluate approaches that improve model robustness and reproducibility across scanners, institutions, staining protocols, and patient populations. - Investigate model interpretability techniques to explain predictions, strengthen clinician trust, and identify opportunities for model improvement.

- Build and enhance tools, workflows, and pipelines that enable efficient, reproducible experimentation, validation, and deployment of machine-learning models. - Conduct rigorous model evaluation, analyze experimental results, troubleshoot model behavior, and communicate technical findings clearly. - Collaborate with ML scientists and engineers alongside product, biostatistics, clinical development, regulatory, and quality teams throughout model development and validation. - Support regulatory and quality documentation associated with AI model development, evaluation, and validation. - Contribute to peer-reviewed research, conference presentations, and collaborations with academic and industry partners. Requirements - At least 1 year of experience developing machine-learning or deep-learning models using PyTorch, TensorFlow, or comparable frameworks, including relevant master's-level or graduate research experience. - Familiarity with oncology and biomarker development, including cancer biology, treatment pathways, clinical endpoints, risk stratification, and the characteristics of clinically actionable biomarkers. - Experience working with real-world datasets and applying appropriate metrics and validation methodologies to evaluate machine-learning models. - Strong Python programming skills and familiarity with modern software-engineering practices, including version control, testing, code review, and maintainable development workflows. - Ability to analyze experimental results, investigate model behavior, troubleshoot technical issues, and communicate conclusions effectively. - Strong collaboration skills and the ability to work effectively with machine-learning engineers, scientists, clinicians, and other cross-functional stakeholders. - Experience with complex clinical datasets such as medical imaging, multi-omics, longitudinal patient records, clinical studies, or multi-institutional cohorts is highly valuable. - Familiarity with weakly supervised learning, multiple-instance learning, survival analysis, or related machine-learning techniques is preferred.
