We are looking for dynamic colleagues who share our passion for technology and care for our planet. In return, we offer you great career opportunities to grow yourself in a truly global culture where respect, value creation, collaboration, integrity, and gratitude are highly valued and exhibited in everything we do.

Key Responsibilities & Accountabilities

• Method Development & Analytical Validation
  • Analyze complex customer process stream compositions (e.g., natural gas, NGL, LNG, refining cuts, petrochemical matrices) to design custom chromatographic separation methods.
  • Define optimum column stationary phase chemistries, film thicknesses, particle sizes, internal diameters, and column length combinations for target separations.
  • Calculate and optimize physical property calculations (e.g., Calorific Value/BTU, Density, Compressibility, Boiling Point Distributions) within GC software scripts.
  • Prepare calibration standards, run repeatability and drift studies, and establish Method Detection Limits (MDL) and quantification limits for trace component analyses (e.g., trace sulfur, oxygenates, moisture).

• Column Chemistry & Preparation Oversight
  • Establish technical recipes and quality control standards for column packing (packed columns) and phase coating/deactivation (capillary columns).
  • Work directly with Lab Technicians to audit column preparation workflows, evaluate baseline bleed profiles, and troubleshoot column batch variations.
  • Conduct root-cause analysis on column degradation, stationary phase stripping, and matrix contamination issues encountered during system testing.

• Engineering & Application Support
  • Collaborate with Proposal Engineers during the bidding phase to evaluate challenging stream compositions and confirm theoretical feasibility (cycle time , Detection limits, Peak resolution, etc).
  • Provide specialized analytical support to Tuning Engineers during Factory Acceptance Testing (FAT) when handling difficult matrices, non-linear detector responses, or co-eluting peaks.
  • Prepare standard application notes, calibration protocols, chemical safety datasheets (SDS), and analytical technical guides.

Qualification and Experience

• Education: Master’s or Bachelor’s Degree in Chemistry, Analytical Chemistry, Chemical Engineering, or a related physical science.
• Experience: 4–7 years of professional experience in chromatography method development, or application engineering—with specific exposure to gas chromatography (GC).

Competencies

• Analytical Problem-Solving: Systematic, scientific approach to resolving complex separation issues, peak co-elutions, baseline drift, and matrix interference.
• Precision & Scientific Rigor: Uncompromising commitment to analytical accuracy, calibration integrity, and precise record-keeping.
• Cross-Functional Collaboration: Ability to translate complex chemical principles into practical engineering inputs for technicians, tuning engineers, and project managers.

Skills

• Deep knowledge of gas chromatography principles: partition/adsorption mechanisms, column phase selection, carrier gas physics, and detector mechanics (FID, TCD, FPD).
• Familiarity with international standard test methods relevant to process industries (e.g., ASTM D1945, ASTM D5504, GPA 2261, ISO 6974).
• Hands-on proficiency with GC data handling systems, peak integration algorithms, calibration routines, and chemical safety management.
