Are You Someone Who Can

Modelling and pricing

• Build, maintain and review pricing and cash-flow models, including waterfall analysis and hedge valuation, for securitisations, repacks, credit-linked notes, conduit funding and pooled credit structures.
• Develop and validate structured credit models, and test them before they are relied on for pricing or committee decisions.
• Price transactions and run stress, sensitivity, default, prepayment and rating-scenario analysis.
• Model the capital, funding and liquidity effect of structures on the bank and on clients.

Analysis and data

• Analyse cash-flow and asset performance data on new and closed transactions.
• Work with large loan-level and portfolio datasets: clean them, interrogate them and turn them into model inputs.
• Research credit performance, market trends and modelling techniques relevant to the team's structures.

Deal support

• Own the modelling workstream on each transaction and deliver it accurately under deal pressure and tight timelines.
• Turn model output into term sheets, credit papers, committee submissions and client presentations.
• Present and explain model results to clients, alongside the deal team.
• Review transaction documents with internal and external lawyers to confirm they match the model: priority of payments, triggers, definitions and reporting.
• Support the set-up and running of ring-fenced issuer vehicles, including investor and noteholder reporting.

South African regulatory context

• Apply the Banks Act framework to structures, including the Securitisation Exemption Notice and Commercial Paper Exemption Notice and the Regulations relating to Banks.
• Take account of JSE debt listing requirements and exchange control rules where they affect a structure.

Tools and model governance

• 2 to 4 years' post-graduate experience in quantitative modelling, in structured finance, credit, corporate and investment banking, insurance or an actuarial role.
• A strong modelling background, including building financial models from first principles, not only running existing ones.

Advantageous

• Good progress on the Actuarial Society of South Africa (ASSA) exams; Technical Member (TASSA) or Associate (AMASSA) status.
• CFA, FRM, or CA(SA), or relevant engineering qualification, completed or in progress.
