• Design, build, and evaluate AI-enabled solutions using large language models, generative AI, retrieval-augmented generation, embeddings, vector search, prompt engineering, and model orchestration frameworks

• Implement best practices in LLM-based engineering, including RAG frameworks, evaluation approaches, guardrails, monitoring, and continuous improvement

• Develop and apply machine learning, statistical modelling, and mathematical optimization techniques to support predictive decision-making, scenario analysis, resource allocation, portfolio construction, and other complex business problems

• Translate business objectives, constraints, and trade-offs into analytical, AI/ML, or optimization-based solution approaches

• Champion strong coding standards, including documentation, version control, testing, reproducibility, and code review practices

• Contribute to building and promoting best practices across the team by sharing knowledge, reusable patterns, and lessons learned

• Stay up to date with emerging technologies, industry trends, and advancements in AI, machine learning, optimization, and data science

• Explore and experiment with new techniques, tools, models, and data sources, providing thoughtful recommendations to the business

• Collaborate with team members on research, analysis, experimentation, and idea generation, while progressively developing independent insights

• Build strong partnerships with business stakeholders, particularly within Private Markets, to drive impactful data-driven, AI-enabled, and optimization-based solutions

• Support the delivery of key reports, analytics, models, visualizations, prototypes, and decision-support tools aligned with business priorities.

• Continuously identify opportunities to enhance AI/ML and optimization approaches, leveraging new techniques, emerging tools, and alternative data sources

What you'll need

• Bachelor's degree in a quantitative discipline.

• Master's or Ph.D. degree in a quantitative discipline with a data science, statistical modelling, machine learning, AI, optimization, or computer science focus preferred.

• Machine learning, data science, AI engineering, or applied analytics experience in industry or an academic setting.

• Experience in mathematical and statistical model development to support predictive decision-making

• Experience or strong familiarity with large language models, generative AI, retrieval-augmented generation, embeddings, vector databases, prompt engineering, and LLM evaluation

• Experience or strong familiarity with mathematical optimization techniques, such as linear programming, mixed-integer programming, nonlinear optimization, stochastic optimization, simulation-based optimization, or heuristic methods is a huge asset

• Experience formulating business problems as analytical, machine learning, AI, or optimization problems, including defining objectives, constraints, trade-offs, and success measures

• Proficient programming skills in Python, R, Spark, or other open-source programming languages and related libraries

• Experience with relevant data science, machine learning, AI, or optimization libraries and tools, such as scikit-learn, PyTorch, TensorFlow, Hugging Face, LangChain, LlamaIndex, OR-Tools, Pyomo, Gurobi, CPLEX, CVXPY, SciPy, or similar

• Proficient SQL skills in mining complex and multi-sourced data environments

• Experience in both on-premise and cloud computing environments

• Experience analyzing large sets of data for patterns and correlations using visualization tools

• Proficient with Git workflow

• Good coding habits, including documentation, version control, testing, reproducibility, and code review

• Passionate about applying analytics, AI, machine learning, and optimization in the investment area

• Ability to quickly learn and adopt new technologies, tools, and approaches

• Ability to independently research potential solutions from industry, open-source, vendor, and academic resources

• Ability to articulate thoughts and ideas to effectively collaborate with business, data, and technology partners

• Strong problem-solving skills working in a team-based environment

• Previous experience in investments, capital markets, private equity, or private markets is an asset.
