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.
- Communicate complex technical concepts and validation findings to technical and non-technical stakeholders, while ensuring that the risk management process is followed.

- 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.

- 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 workplace.
