Your responsibilities

System Architecture
  • You will collaborate with product management and key stakeholders to understand and shape the business vision and its impact on architectural blueprints/runways.
  • You will take responsibility for the architectural design within a defined scope (for example, a domain).
  • You will work with the product manager and product owner to define high‑level solution intent (blueprint), including roadmap, information models and documentation expectations.
  • You will identify enabler epics (initiatives, stories) and make dependencies transparent.
  • You will define subsystems and their interfaces, allocate responsibilities and understand deployment as well as interactions with the surrounding solution context.
  • You will plan and develop the architectural runway for your system to support business features, the technical vision and the blueprint, and support teams in technical design.
  • You will ensure adherence to enterprise architecture standards and support the long‑term sustainability of the system.
  • You will prepare options and request exceptions when deviations are required.
  • You will manage the application lifecycle and work toward reducing architecture debt, communicating this transparently and protecting applications/platforms from excessive debt accumulation.
Planning
  • You will work with other system architects, shared services, the system team and the enterprise architect to define the architectural approach and capability roadmap.
  • You will contribute to the QBR process and to the high‑level objectives for the upcoming PI planning (enablers).
  • You will help summarise findings into an agreed set of PI solution objectives and validate alignment of the technical directions.
  • You will support teams in defining features and breaking them down into stories.
Collaboration
  • You will identify risks related to deviations from standards or innovation.
  • You will work with discipline architects to address identified issues and contribute to bank‑wide solutions.
  • You will collaborate with stakeholders, customers and suppliers to ensure the architectural direction remains aligned with the system intent.
  • You will make sure that the technical characteristics of supplier‑delivered capabilities are well understood and support their integration into the architecture.
