Job Summary

The role of Specialist System Design is to take ownership of the detailed functional design and production of subsystem components, whether based on a packaged solution or on custom development.

This requires working with product management, architecture, internal business clients, operations officers, and end users to understand the End-to-End architecture, requirements, expected use-cases and interfaces of the subsystem components.


This role also implies working with other System Designers in the team to ensure consistent application of the process and best practices expected all members.

System Designers are also involved in the development, testing, integration, delivery, and support phases of the project.
