• Demonstrated ability to mentor and develop others.

• Collaborative, proactive, and able to work independently or as part of a team.

Essential Technical Skills

• Strong proficiency in Python and PyTorch for machine learning.

• Up-to-date knowledge of modern ML image models (e.g., vision transformers, ConvNeXt, diffusion models such as Stable Diffusion, and foundation models).

• Solid understanding of image analysis techniques for noisy data.

• Strong coding skills and experience with version control and bug tracking tools.

• Experience working within quality management systems and regulated environments.

Desirable Skills

• Experience with cloud-based ML infrastructure (e.g., AWS EKS, Rancher).

• Familiarity with ML experiment tracking tools such as Weights & Biases.

• Track record of innovation and IP generation.

• Experience in agile development environments.

• Ideally you will have worked within medical imaging in a regulated environment:

• Experience with medical image analysis and DICOM.

• Familiarity with regulatory standards (ISO13485, EU AI act).

• Knowledge of regulatory pathways for medical devices (FDA, CE).

• Experience collaborating with clinical teams.

We would prefer this to be a Cardiff office-based role, but will also consider hybrid working.
