to further

grow and sustain digital trust

across Canada. Our mission is to

empower frictionless trust in every interaction.

EnStream is dedicated to increasing trust and convenience for Canadians using real-life, verified identities and network data held by trusted telco networks. At EnStream, every team member plays a critical role in shaping our strategy and delivering meaningful impact across industries. About the Role

We’re building critical R&D; and validation runway for our next-generation fraud and trust-scoring models — spanning tabular, graph, and foundation model. The Research ML Scientist to lead model R&D; and own model validation end-to-end. This is a hands-on, high-ownership role for someone who wants to shape the modeling and validation standards behind a national-scale digital trust platform. What You’ll Do

Lead R&D; on the progression of our fraud and trust-scoring models across tabular, graph, and foundation model approaches Own model validation end-to-end, including designing and running validation frameworks, testing methodologies, and performance benchmarks appropriate for a regulated environment Evaluate and recommend model architectures for applicability to fraud detection and identity trust use cases, balancing performance,



interpretability, and regulatory requirements Document model development decisions, validation results, and testing rationale to support audit and regulatory review Partner cross-functionally to keep model delivery on track What You Bring

Must-Have Skills & Experience

Advanced degree (PhD preferred) in Data Science, Computer Science, Statistics, or a related quantitative field, or equivalent practical experience Demonstrated experience leading applied ML R&D;, ideally spanning tabular models, graph-based models, and/or foundation models Strong background in model validation methodologies, particularly within regulated or high-stakes environments Proficiency in Python and standard ML/data science tooling; strong SQL skills Experience taking models from research or prototype stage through to production-grade delivery Ability to work independently and take ownership of ambiguous, high-priority initiatives under time pressure Strong written and verbal communication skills, including documenting technical decisions for regulatory or audit purposes Preferred Qualifications

Experience in fraud detection, identity,



or digital trust domains Experience with graph neural networks or graph-based feature engineering Familiarity with foundation model fine-tuning or adaptation for tabular or graph data Experience operating within a regulated industry (financial services, telecom, or similar) Why Join Us?
