• Provide technical design input to mechanical architectures, interfaces and key design features.
• Lead assigned work packages and, where appropriate, an engineering programme (Project Engineering Lead), with accountability for technical scope, delivery, risk and engineering outcomes. Contribute to design trade studies, concept evaluation and selection of technically robust solutions.
• Coordinate engineering activities across disciplines in support of work package or programme objectives, without line management responsibility.
• Guide design intent and ensure alignment with requirements, environmental constraints and lifecycle considerations.
• Review, approve and technically assure mechanical design outputs including drawings, analyses, specifications and substantiation evidence.
