Comfort writing non-trivial SQL, ideally on BigQuery or another cloud warehouse.

A strong eye for detail and a habit of testing and reconciling numbers until they're right.

Clear communication, and the confidence to challenge and clarify requirements with finance teams.

A MSc in Finance, or progress towards a professional qualification such as CFA or CAIA (Level I or above), or equivalent.

Advantageous
