• Perform and contribute to process safety studies (HAZOP, LOPA, relief systems);
• Conduct process simulation and modelling (e.g. Aspen, CFD) to validate design performance;
• Define plant capacity, equipment sizing, and process optimisation strategies;
• Work with external licensors, vendors and consultants to ensure robust technology selection;
• Support project delivery through design reviews and technical input across global teams.

What you will bring

• Degree in Chemical Engineering;
• At least 5 years of experience in process design, modelling, or project engineering;
• Strong understanding of process safety and manufacturing principles;
• Experience or exposure to process simulation tools (Aspen, ProSim, etc.);
• Ability to work across multiple stakeholders and global teams; and
• Experience in ammonia, nitric acid, ammonium nitrate or sodium cyanide would be highly regarded.
