• Hands-on experience with triple quadrupole mass spectrometry
• Experience with LC/MS/MS and/or GC/MS/MS method development or analysis
• Familiarity with ISO/IEC 17025 laboratory quality systems or other regulated analytical environments
• Experience with Sciex LC/MS/MS platforms and Agilent GC/MS/MS instrumentation
• Experience with pesticide residue or multi-residue analytical methods
• Experience working in ISO/IEC 17025 accredited laboratories
• Strong background in Microsoft Excel
• Experience developing or refining multi-residue pesticide methods and improving analytical sensitivity, robustness, and throughput in high-volume analytical laboratories is highly valued
• Strong analytical, troubleshooting, and problem-solving skills
• Ability to work in a fast-paced environment supporting testing of food products and environmental samples

• Developing, optimizing, and validating analytical methods for pesticide residue analysis
• Developing and validating quantitative multi-residue analytical methods for pesticide analysis using LC/MS/MS and GC/MS/MS, including optimization of chromatographic separation, ion transitions, and mitigation of matrix interferences
• Operating, maintaining, and troubleshooting LC/MS/MS and GC/MS/MS (triple quadrupole) instrumentation, including Sciex LC/MS/MS and Agilent GC/MS/MS systems
• Performing quantitative analysis using advanced chromatographic and mass spectrometry techniques
• Analyzing, interpreting, and reporting analytical data for identification and quantitation of analytes
• Designing and evaluating experimental approaches to improve analytical performance, including sensitivity, selectivity, and robustness of pesticide residue methods
• Ensuring laboratory activities comply with ISO/IEC 17025 quality management requirements, including proper documentation, traceability, and data integrity
• Preparing and maintaining technical documentation such as method validation reports, SOPs, and analytical procedures in accordance with ISO/IEC 17025 standards
• Supporting method validation, verification, and measurement uncertainty assessments as required under laboratory accreditation guidelines
• Participating in proficiency testing, quality control programs, and internal audits to support laboratory accreditation
• Contributing to evaluation and implementation of approved chemical methodologies for food and environmental testing
• Assisting in scientific research initiatives and continuous improvement of laboratory analytical processes
