Senior AI Machine Learning Engineer (Montreal)

About the Role

We are hiring a Senior Machine Learning Engineer Scientist to lead the development of scalable graph‑based and transformer‑based modeling systems, along with production‑grade ML pipelines. This role sits at the intersection of research and systems engineering and will help shape the next generation of relational foundation models for structured data.

Responsibilities

• Architect and drive scalable development of foundation models for relational and graph data.
• Design high‑performance data pipelines for large‑scale graph, relational, and tabular datasets.
• Establish best practices for experimentation, reproducibility, evaluation, and deployment.
• Define and execute the technical roadmap for ML infrastructure and modeling frameworks.
• Develop and optimize Graph Neural Networks (GNNs), Graph Transformers, Relational Transformers, and self‑supervised, contrastive, or related pre‑training strategies for struct...
