Participate in design reviews, HAZOPs, ALMs, and constructability workshops, ensuring timely resolution of actions.
Ensure designs incorporate operational, maintenance, lifecycle, and whole-life performance considerations from the outset.
Lead design constructability assessments and facilitate the development of safe, practical, and cost-efficient construction methodologies in line with CDM Regulations.
Provide responsive technical support during construction and commissioning to ensure design intent is correctly implemented and validated.
Liaise with site teams to address technical issues, update drawings and documentation, and support testing and commissioning activities.
Conduct site assessments and produce clear engineering reports with actionable recommendations.
Tools, Systems & Digital Engineering
Develop, manage, and validate intelligent P&IDs, ensuring accurate metadata, tagging, and integration with automation/control systems.
Collaborate with the EICA teams on the relevant CDE (ACC) to ensure control, telemetry, and automation requirements are fully represented in design outputs.
Proficiently use the Microsoft Office suite (Excel, Word, PowerPoint, Teams, etc.) for documentation, reporting, scheduling, and technical analysis.
Support digital workflows and system integration to enhance design quality and efficiency.
Continuous Improvement & Business Support
Contribute to tender-stage design proposals, providing innovative and robust technical inputs.
