Job description

The project is part of the Credit, Asset-backed & Securitized Products (CASP) division of an investment bank, focusing on platforms that support securitization and structured finance products. The current primary objective is migrating existing on-premise systems to a modern Microsoft Azure cloud environment, transforming legacy architecture into scalable, cloud-native solutions. It involves rebuilding and adapting systems used for structuring, processing, and distributing securities such as ABS, MBS, and CLOs. The platform integrates with trading, risk, and regulatory systems to support both real-time and batch data processing. The target architecture follows a microservices-based approach with containerized services deployed on Azure Kubernetes Service (AKS). Infrastructure provisioning and configuration are managed using Terraform as Infrastructure as Code. The system leverages REST APIs and event-driven communication to ensure scalability and flexibility during and after migration. Special focus is placed on maintaining data consistency, performance, and regulatory compliance throughout the transition. The project emphasizes high availability, resilience, and observability in a complex financial ecosystem. AI-assisted development tools like GitHub Copilot are integrated to enhance engineering productivity. The environment promotes modern engineering practices, automation, and continuous improvement.
