• Identify technical risks, design issues and improvement opportunities early in the project lifecycle.
• Provide mentoring, coaching and technical guidance to junior engineers.
• Support tender development, technical proposals and project delivery activities.
• Collaborate closely with project managers, engineering teams and key stakeholders to deliver successful project outcomes.
• Contribute to the development of engineering standards, templates, processes and continuous improvement initiatives.
