About the Role
We are looking for a Senior Principal, Algorithms Engineer to join the R&D team developing medical imaging AI solutions focused on segmentation, analysis, and 3D reconstruction to develop medical applications.
This is a hands‑on role with responsibility for building, integrating, and maintaining end‑to‑end ML-driven systems, from data ingestion and model development through inference, deployment, and application integration.
How you will make an impact:
Architecture & Engineering
- Contribute to system architecture and engineering standards across ML, data, and deployment components.
- Design and implement end‑to‑end ML systems, covering data pipelines, model training, inference services, and application integration.
- Participate in design reviews and technical decision‑making with a strong hands‑on implementation focus.
Medical Imaging & Machine Learning
- Apply deep understanding of ML development practices, including model architecture design, training strategies, evaluation, and inference optimization.
- Optimize models for volumetric medical data with respect to accuracy, memory usage, and runtime performance.
- Develop and optimize deep learning models for medical image segmentation.
Data Handling & Preprocessing
- Build and maintain production‑grade pipelines for large DICOM datasets.
- Implement robust preprocessing and augmentation workflows supporting both training and inference at scale.
Integration, Deployment & MLOps
- Integrate ML models into production medical applications and backend services.
- Design and implement inference and deployment strategies, including model versioning, performance tuning, and reliability in AWS‑based environments.
- Work closely with other software developers to integrate ML solutions into the broader platform and end‑user applications.
Quality, Validation & Collaboration
- Work closely with SQA & Automation engineers to design ML systems for testability and to implement advanced validation strategies, including end‑to‑end, regression, and performance validations.
- Support CI/CD pipelines by enabling automated testing and validation of ML models, data pipelines, and application integrations.
Collaboration & R&D
- Collaborate with engineering, QA, clinicians, and product teams to validate functionality, performance, and usability.
- Stay current with advances in modern ML architectures, training techniques, and deployment practices, contributing hands‑on to R&D initiatives.
What you’ll need:
- MSc. in Computer Science, Software Engineering, Biomedical Engineering, or equivalent practical experience.
- 8+ years of professional Algorithms and Software Development experience, including hands‑on ownership of end‑to‑end ML systems from design to production.
- Deep knowledge and understanding of machine learning development, including modern architectures, training methodologies, inference optimization, and deployment.
- Strong Python skills with proven hands‑on experience using PyTorch.
- Proven experience with
- U‑Net variants (3D U‑Net, nnU‑Net)
- 3D CNNs
- MONAI
- 3D Slicer
- YOLO variants
- and medical image segmentation pipelines.
- Solid knowledge of medical imaging data formats (DICOM, NIfTI).
- Strong foundation in image processing and computer vision.
- Experience optimizing GPU‑accelerated and performance‑sensitive ML workloads.
- Practical experience with CI/CD pipelines, automated testing, and Git‑based workflows.
- Excellent documentation skills; strong English communication; collaborative and accountable team player.
What else we look for:
- Advanced degree (M.Sc./Ph.D.) in a relevant field.
- Experience deploying ML systems on AWS (including SageMaker).
- Experience working in regulated or medical software environments.
- Background in 3D visualization or interactive medical applications.
- Full‑stack experience (Node.js, React, PostgreSQL).
