You will also be expected to use your data science experience to mentor and guide junior members of the team.

Position Responsibilities:

• Provide independent challenge and constructive feedback for AI/ML, GenAI, and agentic models by identifying model weaknesses, limitations, assumptions, and risks, and recommending appropriate remediation actions.
• Manage competing deadlines, competing expectations, and coordinate procedural alignment to ensure the balance of risk management activities is commensurate with the business risk exposure.

• Mentor and support junior data scientists through technical coaching, knowledge sharing, and review of validation approaches and methodologies.

Required Qualifications:

• Master's degree or higher in Statistics, Biostatistics, Data Science, Engineering, Mathematics, or a related quantitative field.
• At least 3-5 years of a mix of hands-on data science experience (data science, statistics, AI/ML model development, AI/ML research, model validation, model risk management, or a related quantitative discipline) and a stakeholder-exposed role (functions that interact with varying teams and business units across the organization.)
• Strong critical thinking skills and the ability to independently challenge assumptions and assess model risk in the context of the business problem it solves.
• Hands-on keyboard report writing and code implementation; being able to implement your ideas yourself.
• Experience interpreting model performance metrics and conducting quantitative analyses in a variety of standard and non-standard contexts.
• Strong communication, written documentation, and stakeholder management skills.
• The ability to collaborate with parties from all walks of a large corporation.

Preferred Qualifications:

• Prior model validation experience for AI/ML models or development of AI/ML models for production environments with tangible risk exposures. Comparable experience includes model development in stringently risk-controlled contexts such as pharmaceuticals, aerospace, etc.
• Knowledge of AI governance and model risk regulatory expectations, with emphasis on OSFI E-23.
• Familiarity with Responsible AI concepts, including fairness, explainability, robustness, transparency, safety, and monitoring. Being passionate about Responsible AI is a plus.
• Experience evaluating Generative AI, LLMs, RAG systems, or agentic AI solutions built or customized to solve a very broad range of business problems.
• Experience developing validation frameworks, testing libraries, or automated assurance tooling.
• Experience working in a global, cross-functional environment.
• Experience performing research on AI/ML models in academic or industry settings.

• We’ll empower you to learn and grow the career you want.
