The Opportunity

In this 3-month internship, you will apply your knowledge to improve AI reasoning across complex financial workflows. You will help develop, evaluate, and refine high-quality training data that enables AI models to reason more accurately about financial analysis, valuation, transactions, and investment banking use cases.

• Evaluate AI-generated responses for financial accuracy, reasoning quality, technical rigor, and completeness using structured evaluations.

• Collaborate with domain experts to translate finance expertise into high-quality evaluation criteria and training signals.

• Identify common failure modes in financial reasoning, modelling assumptions, valuation methodologies, and transaction analysis.

• Document best practices, reasoning frameworks, and evaluation guidelines to improve AI performance across financial domains.

This role will be a great fit if you

• 1+ years of professional experience in investment banking, private equity, equity research, transaction advisory, valuation, corporate finance, or a closely related analytical role.

• Possess strong knowledge of financial modelling (including LBOs), valuation methodologies (DCF, comparable companies, precedent transactions), financial statements, and M&A processes.

• Can critically assess financial reasoning and identify errors, unsupported assumptions, and gaps in analysis.

• Communicate clearly and can explain why a piece of financial reasoning is correct or incorrect.

• Are comfortable working with ambiguity, iterative feedback, and evolving evaluation standards.
