Density, viscosity, pour/cloud/freeze points; volatility and thermal stability (TGA, NOACK, vapor pressure), Mercury Intrusion Porosimetry SEM/TEM/EDX microscopy, XRD, chemical and physical absorption for contamination, catalyst, coke, deposit analysis, particle size, and maximizing the value of hydrocarbons through thorough understanding of crude yields and qualities to inform economic decisions for value chain optimization and marketing equity crudes.

• Perform advanced analytical testing including Mercury Intrusion Porosimetry (MIP), Differential Scanning Calorimetry (DSC/MDSC/PDSC), Thermogravimetric Analysis (TGA), and hydrogen chemisorption.
• Support physical property testing including density/API, viscosity, pour/cloud/freeze point, and thermal measurements.
• Deliver accurate analytical results within required turnaround times.
• Offer advanced materials, contamination, and particle characterization to help ensure crude assay quality, refinery operability, reliability, and product performance.
• Identify wax presence and Wax Appearance Temperature (WAT) to aid crude handling, pipeline assessment, and assay planning.
• Lower dependence on external labs and reduce time from problem detection to corrective action.
• Prepare clear reports for customers.
• Develop and maintain SOPs and support equipment troubleshooting and implementation of new instrumentation.
• Adhere to safety standards and properly handle hazardous materials.
• Work with cross-functional teams and communicate technical findings clearly.
• Train and mentor team members as needed.

• Bachelor’s degree in chemistry or related area.

• Experience with Mercury Intrusion Porosimetry, SEM/TEM/EDX microscopy, XRD, chemical and physical absorption for contamination, catalyst, coke, deposit analysis, particle size.
• Familiarity with density/API, viscosity and viscosity index, freeze/cloud/pour points, insolubility, thermogravimetric analysis (TGA), TGA–Mass Spectrometry (TGA‑MS), vapor pressure (TGA‑DTA methods), NOACK volatility, flash point (TAG & Pensky‑Martens, extended range), and distillation.
• Proven expertise in direct analysis and sample preparation.
• Advanced troubleshooting abilities for analytical methods and instruments.
• Skilled with Microsoft Office (Word, Excel, PowerPoint, Outlook).
• Strong verbal and written communication, multitasking, customer service, and interpersonal skills.
• Leadership and project management experience.
