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
Solid 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? Contribute to a national-scale initiative defining the future of digital trust in Canada
Work on cutting-edge fraud detection applications using real-world identity data
Collaborate with a lean, highly skilled team where your work has outsized impact on the roadmap
