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.

Whatyou’llneed:

• 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).
