Job description

Project description

Developing cloud-based compliance state-of-the-art archive products to archive and retain real-time communications data in line with internal and external regulatory requirements. The product is developed in-house in an agile development setup based on business requirements from multiple stakeholder parties. By employing continuous development and deployment principles, the team is aiming to transition from project to product management to support the bank with robust compliance archive solutions for the next decade. For a large global investment bank, we are looking for GCP-qualified cloud engineers to help with the FIC (fixed income and currencies) cloud migrations under Project Cirrus. Knowledge of Financial Services/FIC would be great, but the primary skills we need are in building, migrating, and deploying applications to GCP, Terraform module coding, Google infrastructure, cloud-native services such as GCE, GKE, CloudSQL/Postgres, logging and monitoring, etc., and good written and spoken English, as we would like these engineers to help with knowledge transfer to our existing development & support teams. We would like to place people alongside the engineers they'll be working with in the bank.

Code Quality & Best Practices: Establish and enforce coding standards, best practices, and design patterns for front-end development. Conduct regular code reviews and ensure adherence to security guidelines. Testing & Quality Assurance: Write comprehensive unit, integration, and end-to-end tests to ensure the robustness and reliability of UI components and applications. Architectural Contributions: Contribute to the overall front-end architecture, selecting appropriate technologies, defining technical roadmaps, and making informed design decisions.
