  • Produce clear, timely, and technically accurate test reports, certificates of analysis (COA), and chain-of-custody documents for internal stakeholders, suppliers, and regulatory customers.
  • Maintain rigorous QA/QC procedures including running standards, blanks, reference materials, proficiency tests, and participating in inter-laboratory comparisons to ensure analytical integrity.
  • Adhere to laboratory safety, hazardous materials handling (HAZMAT), and environmental protocols including SDS management, PPE use, spill response, and safe storage/disposal of fuels and solvents.
  • Support field testing operations including portable analyzers, on-site sampling, and immediate pass/fail screening to support production decisions and emergency response.
  • Assist in development and revision of Standard Operating Procedures (SOPs), test methods, and work instructions to reflect best practices, regulatory updates, and continuous improvement initiatives.
  • Maintain laboratory supplies, reagents, and consumables inventory; coordinate with procurement and vendors to ensure uninterrupted operations and cost-effective sourcing.
  • Train and mentor junior technicians and contractors on sampling technique, instrument operation, data entry, QA/QC checks, and safety expectations to build team capability and consistency.
  • Coordinate sample logistics with operations, dispatch, and third-party laboratories including packaging, labeling, shipping documentation, and temperature-controlled transport when required.
  • Perform microbiological fuel testing (where applicable) for contamination and biodegradation indicators and work with microbiology specialists to mitigate microbial fuel issues.
  • Conduct trend analysis and statistical process control (SPC) on serial test data to identify drifting instruments, batch anomalies, or production quality trends and recommend process adjustments.
  • Provide technical support to production, blending, maintenance, and sales teams on fuel specifications, incompatibility issues, and product acceptance criteria.
  • Participate in internal and external audits (ISO 17025, customer audits) and implement audit findings, including evidence collection, corrective action plans, and improvement verification.
  • Ensure proper labeling, storage, and documentation of retained samples and reference materials; manage sample retention schedules aligned with contractual and regulatory requirements.
  • Implement and monitor contamination control practices for sampling points and transfer lines to minimize cross-contamination and false positives in analysis.
  • Prepare and manage weekly/monthly KPI reports for lab performance, turnaround time (TAT), test throughput, error rates, and corrective action metrics for laboratory management review.
  • Support development and piloting of new test methods for emerging fuel types (biofuels, renewable diesel, blended fuels) including small-scale R&D testing and scale-up verification.
  • Liaise with external laboratories, standard bodies, and vendors to stay informed of method changes, new reference materials, and instrument upgrades relevant to fuel testing best practices.

Secondary Functions

  • Support cross-functional projects involving operations, maintenance, safety, and procurement to improve sampling infrastructure and test turnaround times.
  • Provide technical input for supplier qualification, incoming fuel acceptance criteria, and contract specifications.
  • Contribute to continuous improvement initiatives such as 5S, Lean, or Six Sigma projects that affect laboratory workflows and sample throughput.
  • Participate in emergency response drills and contribute to the site-level hazardous materials response plan.
  • Assist commercial teams with technical inquiries, claims support, and clarifications related to test results and product specifications.
