Process Engineer

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 place—to 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, and—where available—drone, 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 top‑down vs. bottom‑up 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, OGMP‑style progress where applicable).

We are known for our extraordinary people who make the impossible possible every day. Questians are driven by hunger, humility, and aspiration. We believe that our company culture is the key to our ability to make a true difference in every industry we reach. Our teams regularly invest time and dedicated effort into internal culture work, ensuring that all voices are heard.

We wholeheartedly believe in the diversity of thought that comes with fostering a culture rooted in respect, where everyone belongs, is valued, and feels inspired to share their ideas. We know embracing our unique differences makes us better, and that solving the worlds hardest engineering problems requires diverse ideas, perspectives, and backgrounds. We shine the brightest when we tap into the many dimensions that thrive across over 21,000 difference-makers in our workplace.

Work Experience

• Process engineer with 3 to 5 yrs experience
• Process engineering fundamentals
• Emissions quantification: fugitives, vents, combustion, flares; calculation of CO₂e using GWPs.
• LDAR methods (OGI, Method 21), understanding of sensor placement, detection limits, and survey design.
• Data analysis and visualization; reconciliation of measurement vs. estimation methods; uncertainty analysis.

Tools & Software

• Process simulation: Aspen HYSYS/Plus.
• Data & visualization: Excel (advanced), Power BI/Tableau; Python basics a plus (pandas, plots).
• PI Systems: PI Vision/PI DataLink for real-time plant data and performance tracking.
• Emissions tools: Company or industry calculators, emissions factor databases, LDAR data systems.
• Document control: SharePoint, quality systems, audit trails.
