This is a hands‑on role where you'll combine quantitative expertise, problem‑solving skills and technology to deliver practical solutions that support the business. You'll be part of a highly skilled team that works closely with the trading floor, giving you exposure to complex products, challenging quantitative problems and opportunities to influence how risk and valuation models evolve over time. This is a permanent position based in Sydney, with the expectation that you’ll work from the office three days per week.
