Senior AI Applied Scientist II at Prenuvo in Vancouver, British Columbia, Canada

Job description

• We are looking for a Senior AI Applied Scientist II to independently own a model domain end-to-end within our AI Research org, from problem framing through validated, production-deployed models.
• As Prenuvo’s AI org moves from task-specific models toward foundational work (meaning pre-trained backbones, multi-task heads, and the addition of clinical text and structured data), we need scientists who design experiments rather than only run them, diagnose failure modes on their own, and shape how the team approaches a whole class of problems. You will work at the intersection of deep learning, medical imaging, and clinical translation, accountable for both the rigor of the science and the delivery of the work.
• This hybrid role is based in Vancouver. We expect you to be technically credible enough to review model architectures, challenge assumptions, and roll up your sleeves when it matters. We also expect you to build a team environment where people do their best work.
• This role does not provide visa sponsorship. Applicants must be legally authorized to work in Canada at the time of hire and must not require employer sponsorship for a work visa (current or future).
• Help reshape the world through proactive healthcare while working with cutting-edge technology and high performing teams with deep expertise - join us to make a difference in people’s lives!

Responsibilities

• Lead development of foundation models and multimodal systems for whole-body MRI, advancing self-supervised and large-scale representation learning across imaging, radiology, lab, and longitudinal data.
• Own experiment design and validation study scoping for your domain, diagnosing failure modes independently.
• Drive the data quality, annotation criteria, and quality standards your models depend on, engaging directly with clinical framing for your domain.
• Guide the strategic application of generative and agentic AI, including LLM adaptation and workflow orchestration, to accelerate research and clinical workflows.
• Contribute modeling approaches that others adopt, and define and execute a research roadmap that advances Prenuvo's foundation-model capabilities.
• Lead clinical review for your domain, partner across clinical, annotation, and ML Engineering, and raise the code-quality bar for the team.
• Deliver production-ready models with documented validation, clinical sign-off, and performance benchmarks, owning the technical narrative for your domain.

Requirements

• Technical depth
• Strong MSc or PhD from a top-tier institution in CS, biomedical engineering, statistics, mathematics, or a related field.
• A minimum of 4 academic or industry years of ML experience, with a strong publication or applied-research record including at least one first-author work.
• Expert-level PyTorch and the ability to write and review production-quality research code.
• Demonstrated ability to own a model domain end-to-end (architecting, training, validating, deploying to a real performance bar) and to design experiments and validation studies independently.
• Deep fluency in self-supervised learning: masked image modeling, contrastive learning, JEPA-style methods, knowledge distillation, and large-scale representation learning.
• Strong command of modern vision and multimodal architectures: Vision Transformers, multimodal transformers, foundation models, and vision-language models.
• Experience in medical image analysis (segmentation, detection, classification, biomarker extraction, longitudinal modeling) and multimodal fusion of imaging with radiology, clinical, lab, and structured patient data.
• Experience applying generative and agentic AI (LLM adaptation, workflow orchestration) to healthcare or research applications.
• Strong collaboration skills across ML Engineering, Product, and Clinical Ops, with high standards for scientific rigor balanced against delivery speed.
• Experience in body composition, vascular imaging, organ segmentation, or lesion detection
• Familiarity with FDA 510(k) submission processes or predicate-based regulatory pathways
• Publications in top journals and conferences such as ISMRM, NeurIPS, MICCAI, ICML, RSNA, etc.
• Experience with interpretable AI and state-of-the-art AI methods
• Prior work in a health tech or clinical AI environment

Skills

Required

• Expert-level PyTorch

Benefits

• An avenue to make a positive impact on people's lives and their health
• We believe in preventative healthcare for everyone, including our team - Prenuvo provides free, whole-body scans to each team member
• Growth opportunities are at the heart of our people journey, we’re doing big things with bright minds - there is no single path to success, it can be shaped along the way
• Building strong relationships is at the core of everything we do - our team gets together each week to connect, share, and socialize
• Recognizing time away to restore is vital to our wellbeing - we have a flexible vacation policy and we will encourage you to use it
• We offer a comprehensive benefits package including health, dental, vision, including Mental Health coverage, to support you and your family
• Prenuvo offers eligible Canadian employees access to both RRSP and TFSA retirement savings plans, with immediate, optional enrollment and the flexibility to invest and save for the future on your own terms. While Prenuvo provides access to these plans, the company does not currently offer matching contributions.
• The base salary for this role ranges from $150,000-$177,000 CAD per year, depending upon experience and geographic location
