Intermediate Applied Machine Learning Scientist – Cancer Care AI Center of Excellence (COE) Siemens Healthineers
Role Summary: The Intermediate Applied Machine Learning Scientist will design, develop, and deploy deep learning solutions for oncology imaging, with a strong emphasis on 3D medical image segmentation, domain adaptation, and adaptive radiotherapy workflows. This role focuses on translating cutting-edge AI research into clinically valuable tools that support radiation oncologists and improve precision in cancer care using CBCT, CT, and multimodal data.
Key Responsibilities Model Development & Technical Innovation:
-
Develop and optimize 3D deep learning models for auto-segmentation of critical structures in cancer imaging on CBCT, CT, and other modalities, leveraging frameworks such as nnU-Net, TotalSegmentator, MedSAM, and similar tools.
-
Implement domain adaptation, transfer learning, pseudo-label fusion, and synthetic-to-real techniques to improve model performance across multi-vendor clinical datasets.
-
Build scalable pipelines for medical image preprocessing, exploratory data analysis, feature extraction, landmark detection (heatmap regression), and high-quality ground-truth dataset curation in collaboration with clinicians.
Clinical Integration & Validation:
-
Advance adaptive radiotherapy applications, including treatment response prediction, dose-volume histogram analysis, and clinical validation using metrics such as Dice Similarity Coefficient (DSC) and AUROC.
-
Ensure models meet regulatory, safety, and performance standards through rigorous experimentation and multi-site validation.
-
Collaborate with radiation oncologists, radiologists, and cross-functional teams to translate clinical needs into robust, production-ready AI solutions.
Research & Collaboration:
-
Contribute to publications, patents, and knowledge sharing while staying current with advances in medical AI.
-
Work closely with clinical partners to refine tools based on user feedback and real-world performance.
-
Support dataset harmonization and annotation pipelines to enable high-impact oncology AI development.
Knowledge, Skills, & Experience:
- The ideal candidate is a hands-on ML researcher with strong expertise in medical imaging and a passion for oncology applications.
-
M.Sc. (or PhD) in Computer Science, Computing Science, Biomedical Engineering, Medical Imaging, or a related field.
-
1–3 years of applied deep learning experience in medical imaging, preferably in oncology, adaptive radiotherapy, or 3D segmentation.
-
Strong proficiency in Python, PyTorch (TensorFlow/Keras a plus), nnU-Net workflows, medical imaging libraries (MONAI, SimpleITK), and tools such as TotalSegmentator and MedSAM.
-
Experience curating clinical datasets, performing domain adaptation, and conducting rigorous validation (Dice, bootstrap CIs, etc.).
-
Familiarity with DICOM data, multi-vendor CT systems (e.g., Siemens), and collaboration with clinical teams.
-
Publications or demonstrated impact in medical AI preferred.
-
Excellent communication and cross-functional collaboration skills.
Technical & Leadership Competencies:
-
3D Medical Imaging Expertise: Deep understanding of CBCT/CT segmentation, landmark detection, and adaptive radiotherapy pipelines.
-
Technical Excellence: Strong problem-solving in domain adaptation, transfer learning, and production-oriented ML workflows.
-
Clinical Focus: Ability to deliver solutions that provide measurable value to oncologists and patients.
-
Collaboration & Communication: Works effectively with clinicians, engineers, and researchers; translates complex concepts for diverse stakeholders.
-
Innovation & Rigor: Balances cutting-edge research with practical, validated clinical outcomes.
-
Integrity & Quality: Committed to responsible AI, patient safety, and regulatory excellence.
