• Interface Control Documents

Our team provides a range of key services, including:

• Requirements Management
• System Architecture Development and Modelling
• Technical Interface Management and System Integration
• Design Assurance, Verification, and Validation Management
• Configuration Management

Key responsibilities and duties include:

• Support capture and translation of stakeholder vision and definition of the scope and boundary of the system, along with its Concept of Operations
• Develop system requirements throughout the system lifecycle, using an appropriate requirements management tool
• Support development of required system architectural views (functional and physical), including, but not limited to Functional, System and Spatial Breakdown Structures
• As directed, apply appropriate scenario modelling and role modelling techniques to contribute to capability assurance evidence
• Work with designers to capture and mature internal and external system technical interfaces

• Understanding of systems engineering techniques applied across the entire engineering lifecycle, with demonstrable experience in a portion of the lifecycle
• Good stakeholder management skills with the ability to communicate complex concepts clearly
• Knowledge of requirements development, preferably for infrastructure projects
• Knowledge, and preferably experience, in applying a Model-Based Systems Engineering (MBSE) approach, including system architecture development against an Architectural Framework
