Job Description Job Requirements At Quest Global, it's not just what we do but how and why we do it that makes us different. With over 25 years as an engineering services provider, we believe in the power of doing things differently to make the impossible possible. Our people are driven by the desire to make the world a better placeto make a positive difference that contributes to a brighter future. We bring together technologies and industries, alongside the contributions of diverse individuals who are empowered by an intentional workplace culture, to solve problems better and faster. Key Responsibilities Process Design & Optimization - Develop and optimize unit operations to improve yield, energy efficiency, and reliability. - Conduct mass/energy balances, heat integration studies, and debottlenecking assessments. - Support start-up/shutdown, turnaround planning, and Management of Change (MoC). Operations & Performance Monitoring - Track KPIs (throughput, energy intensity, specific consumption, product quality) and create daily/weekly performance reports. - Identify deviations, recommend corrective actions, and follow through on closure. Troubleshooting & Reliability - Lead or support root cause analyses for process upsets and equipment failures (columns, reactors, furnaces, compressors, flares). - Collaborate with maintenance and inspection teams for corrective and preventive actions. Methane Monitoring & GHG Calculation (Core Focus) - Methane Emissions Detection & Quantification - Plan and execute LDAR campaigns using OGI cameras, Method 21, and flow measurement devices. - Coordinate with continuous methane monitoring sensors, handheld instruments, andwhere availabledrone, aerial, or satellite data to validate emission sources. - Build and maintain source inventories (fugitives, vents, tanks, compressors, pneumatic devices, flares). - Data Management & Reporting - Build structured datasets and dashboards for emissions (e.g., by unit/source, monthly/annual trends). - Reconcile topdown vs. bottomup estimates; perform methane mass balance checks at unit/site level. - Support reporting to corporate ESG, regulatory submissions, and voluntary frameworks (e.g., corporate sustainability reports, methane intensity targets, OGMPstyle progress where applicable).
