Principal Systems Engineer / Technical Authority

The successful candidate will demonstrate:

Significant systems engineering experience within complex defence, marine, aerospace or other multidisciplinary engineering programmes.

Demonstrable experience generating and maintaining system architectures for complex integrated systems.

Strong experience of requirements management, requirements traceability and management of requirements acceptance / compliance databases, preferably using IBM DOORS.

Practical experience developing, reviewing and managing Interface Control Documents (ICDs) and structured interface data.

Experience generating and maintaining System Definition Documents or equivalent system-level design documentation.

Strong working knowledge of configuration management, baseline management and engineering change control within a controlled engineering environment.

Experience using Product Lifecycle Management (PLM) systems, preferably Windchill, to manage product data, configuration items and controlled engineering information.

Experience supporting systems engineering activities across the lifecycle, including design, integration, verification, validation and acceptance.

Excellent technical communication and stakeholder management skills, with the ability to coordinate complex information across multidisciplinary engineering teams and suppliers.

Ideally candidates will possess experience in one or more of the following:

Royal Navy, Royal Fleet Auxiliary or other naval platform programmes.

Mission system integration involving command and control, communications, navigation, radar, sonar, sensors, data networks or other complex electronic systems.

Engineering programmes progressing from design baseline through installation, integration, trials and acceptance.

Hands-on use of IBM DOORS, Windchill and Microsoft Visio within a configuration-controlled engineering programme.

Model-Based Systems Engineering (MBSE), SysML or architecture modelling using tools such as Cameo, Enterprise Architect or equivalent.

Requirements verification, validation and acceptance planning, including management of objective evidence and acceptance status.

Review and reconciliation of supplier technical data, design artefacts and subsystem engineering outputs against a system-level baseline.

Management of technical queries, deviations, concessions, waivers or engineering change requests.

Design Authority, Technical Authority or systems integration organisations.

Configuration audits, baseline reviews, design maturity reviews or technical governance activities.

Defence engineering environments involving formal assurance, safety, security and configuration control requirements.

The successful candidate should have practical knowledge of:

Systems architecture development, including functional, logical, physical and interface architecture views.

Requirements capture, decomposition, allocation, traceability, verification and acceptance management.

IBM DOORS or equivalent requirements management tools and structured requirements databases.

Interface definition and control, including ICDs, interface registers, interface data and interface change management.

System Definition Documents and other system-level technical baseline documentation.

Configuration management principles, configuration baselines, status accounting and engineering change control.

Product Lifecycle Management principles and tools, including Windchill or equivalent PLM environments.

Microsoft Visio or equivalent tools for development and maintenance of system architecture and interface diagrams.

Systems engineering lifecycle processes, including V-model development, integration, verification, validation and acceptance.

System-level change impact assessment and management of dependencies across requirements, interfaces, architecture and acceptance.

Technical data management, document control and maintenance of authoritative engineering information.

Design reviews, architecture governance, interface management and configuration review processes.
