Knowledge of portfolio positioning and collateral management, including target versus actual exposure, rebalancing and derivatives mechanics. Hands-on experience integrating external APIs, including authentication, account-state interpretation and resilient handling of failures or inconsistent data. Experience implementing operational controls and monitoring for systems where incorrect, duplicate or delayed actions can have financial consequences. Understanding of secure application integration, including credential protection, secret management and environment separation.
