We are seeking a highly motivated and experienced Machine Learning Engineer to develop advanced machine learning (ML), deep learning (DL), and foundational AI models for medical imaging. This role focuses on building robust algorithms for segmentation, quantification, and detection across CT, MRI, and X‑ray. This position sits at the center of a well‑resourced, data‑rich research environment with established infrastructure for multi‑institutional data aggregation, curation, and large‑scale annotation.

St. Jude Children’s Hospital has incredible high‑performance computing resources. The lab leverages curated datasets from diverse sources, dedicated annotation teams, and external engineering support, enabling this role to focus on high‑impact model development, validation, and clinical translation. Many projects are designed with a path toward regulatory clearance via FDA’s 510(k) or De Novo pathways, and the successful candidate will work closely with regulatory and quality experts to support reproducible, well‑documented, and clinically deployable AI solutions.

This role offers a unique combination of academic productivity (authorship opportunities) and real‑world impact through translation into clinical practice.

Machine Learning Engineer

Key Responsibilities

• Develop, train, and validate state‑of‑the‑art ML/DL models for segmentation, quantification, and detection across CT, MRI, and X‑ray
• Design and implement 2D and 3D model architectures (CNNs, transformer‑based, and foundational models)
• Build scalable pipelines for data preprocessing, model training, evaluation, and deployment
• Develop quantitative imaging methods (e.g., volumetrics, density measurements, biomarker extraction)
• Leverage curated, multi‑institutional datasets to ensure model generalizability and robustness
• Collaborate with radiologists and engineering teams to define clinically meaningful outputs
• Produce regulatory‑grade documentation for datasets, model development, validation, and performance
• Ensure reproducibility and traceability of experiments (data, model, and code versioning)
• Work collaboratively with regulatory and quality experts to support FDA 510(k) and De Novo submissions, including providing technical documentation and validation evidence
• Contribute to software quality and security practices, including supporting activities such as vulnerability assessment and penetration testing in collaboration with cybersecurity and regulatory teams
• Utilize modern AI‑assisted development tools (e.g., LLM‑based coding agents) to accelerate development and improve code quality
• Participate in team‑based development practices (code reviews, Git, testing frameworks)
• Support manuscripts, grants, and technical reporting

Minimum Education and/or Training:

• Bachelor’s degree in computer science, data science, information science, business, or related field.
• Master’s degree preferred.

Minimum Experience:

• Minimum Requirement:
  Bachelor’s degree with 5+ years of experience required.
• Experience Exception:
  Master’s degree with 3+ years of experience.
• Experience with programming languages, databases, and software development lifecycle
• Experience with the position‑specific technical stack preferred
• Experience with the position‑specific scientific domain preferred
• Proven performance in earlier role/comparable role

Preferred Qualifications

• 3+ years of experience developing ML/DL models for image analysis
• Demonstrated experience with segmentation, detection, and/or quantitative imaging algorithms (2D and/or 3D)
• Strong proficiency in Python and deep learning frameworks (e.g., PyTorch, Tensor Flow)
• Experience with modern architectures (U‑Net variants, detection frameworks, transformers, or foundational models)
• Familiarity with DICOM and medical imaging workflows
• Strong understanding of evaluation metrics (Dice, IoU, ROC/AUC, sensitivity/specificity)
• Experience with version control and collaborative development (e.g., Git)
• Demonstrated ability to produce clear, structured technical documentation
• Experience using modern LLM‑based…
