Job description

See yourself in our team

As part of the CommSec Line 2 Financial Risk team, you will support financial risk modelling, capital, analytics and oversight across the market and liquidity risk profile. You will help strengthen risk measurement frameworks, stress testing, scenario analysis, risk appetite monitoring and model governance. Working closely with colleagues across Risk, Product, Finance, Technology, Data and the business, you will turn complex analysis into practical insights that support well-informed decisions.

The role will be offered on an 8 month secondment and offers broad exposure across market risk, liquidity risk, collateral adequacy, concentration risk, margin-related exposures and financial risk reporting.

On any given day you will

•Contribute to the development and governance of financial risk models across market risk, liquidity risk, collateral coverage, stress testing and concentration risk.

•Enhance how CommSec measures exposure to market movements, liquidity demands, client concentrations, collateral adequacy and margin requirements.

•Monitor key risk indicators, risk appetite metrics, early-warning indicators and limits, identifying emerging themes and opportunities for improvement.

•Undertake stress testing and scenario analysis across portfolio, client, security and book-level exposures for CommSec products.

•Review and validate model assumptions, data quality, methodology choices and reporting outputs.

•Translate complex modelling outcomes into clear insights and practical recommendations for senior stakeholders and governance forums.

•Partner with Technology and Data teams to improve automation, controls, data lineage and reporting infrastructure.

•Maintain clear documentation and support policy development so models and reporting processes remain controlled and aligned with model risk governance expectations.

•Build trusted relationships with business stakeholders, Model Risk, Internal Audit and governance forums to discuss methodologies, findings, limitations and remediation actions.

Your skills and experience

We are interested in the capability and perspective you can bring. Experience in some of the following areas would be valuable:

•Financial risk, quantitative analysis, treasury, market risk, liquidity risk, or financial risk modelling.

•Stress testing, scenario analysis, exposure modelling, collateral risk, concentration risk or liquidity-risk measurement.

•Financial markets products, which may include equities and equity derivatives.

•Preparing clear senior-level reporting, methodology papers, risk commentary or governance materials.

•Building relationships across diverse stakeholder groups and communicating technical concepts to senior leaders or risk committees.

•Analytical programming languages such as Python, SQL, R, SAS or similar. This capability is desirable rather than essential.

•Relevant tertiary or postgraduate study in quantitative finance, statistics, mathematics, actuarial studies, economics, finance, engineering or a related discipline. Equivalent practical experience is also welcomed.
