Challenger Limited is an ASX-listed investment management firm managing $131 billion in assets (as at 31 December 2024). Life with us is fast moving and always exciting. Together we’re driving to deliver our vision to provide our customers with financial security for a better retirement.
We achieve this goal by providing a work environment where people from diverse backgrounds, with a range of skills and experiences can contribute and succeed.
Join a high-performing Quant Engineering team building critical investment and risk modelling tools across asset classes and liabilities.
Contribute to hands-on development with C#/.NET in a collaborative environment.
We welcome applications from candidates based in Sydney. Our team typically works from the CBD office three days a week, with the flexibility to work from home two days per week.
Are you a hands-on Quant Developer or Quant Engineer with a deep understanding of financial instruments and a strong background in C# development? Join our Quantitative Engineering team, part of the COO function, and play a key role in developing systematic, quantitative investment and risk solutions across asset classes and liabilities.
The team builds and maintains core modelling infrastructure that supports investment decision-making, risk analytics, and regulatory reporting across a broad range of financial instruments and liabilities — including interest rates, FX, credit, derivatives, annuities, and reinsurance. You’ll also play a part in shaping the future direction of our modelling capabilities.

Contribute to shaping the way we integrate with third-party platforms such as State Street
