I’m expanding my consultancy and need seasoned chemical engineers from Pakistan to become part of my core team and tackle a steady stream of projects. The assignments span petrochemical, pharmaceutical and environmental engineering work, so every week can bring anything from early-stage R&D to plant-scale process optimisation and the occasional quality-control audit. The main, non-negotiable requirement: you must be genuinely proficient with Aspen HYSYS and Siemens gProms. Expect to build steady-state and dynamic models, run sensitivity studies, size major equipment, and translate the results into concise technical recommendations that management can act on. Typical deliverables for any given task include: • The native simulation files with clean, converged models • A brief design or optimisation report highlighting assumptions, key results and next steps • Supporting data sheets or calculation spreadsheets where relevant All simulations must close overall mass and energy balances to within 1 % and follow good engineering practice for thermodynamic package selection, convergence criteria and documentation. If you thrive on varied technical challenges, can turn simulations around quickly and communicate findings clearly, I’m eager to hear how you can add value to the team.
