Requirements

  • A Bachelor's degree in a relevant scientific discipline with 5 or more years of progressive laboratory or industry experience demonstrating significant analytical capabilities, or a Master's degree with 3–5 years of laboratory or industry experience, or a Doctoral degree with a thesis focused on related analytical methodologies and hands-on laboratory experience.
  • Hands-on operational expertise and troubleshooting experience with Liquid Chromatography-Tandem Mass Spectrometry (LC-MS/MS) systems.
  • Proficiency in chromatographic data processing, qualitative and quantitative review, and analysis software.
  • Extensive experience with biological sample handling, micro-pipetting, and biofluid extraction techniques.
  • Demonstrated experience developing or validating LC-MS/MS assays in compliance with regulatory frameworks such as CLSI, ANSI/ASB, CAP, NYSDOH, or ISO regulations.
  • Ability to safely handle chemicals and hazardous materials and thorough knowledge of standard laboratory equipment.
  • Deep conceptual and practical understanding of related products and analytical technologies, acquired through developmental experience in academic or industrial settings.
  • Ability to read, critically analyze, and interpret highly technical documents, including peer-reviewed scientific journals, instrument operating manuals, and standard operating procedures (SOPs).
  • Ability to draft comprehensive technical reports, scientific protocols, and business correspondence.
  • Ability to communicate complex technical concepts clearly in individual discussions and small-group collaborative settings.
  • Ability to apply advanced mathematical and statistical concepts to analytical problem-solving, including frequency distributions, assay reliability and validity, analysis of variance (ANOVA), and correlation techniques.

Responsibilities

  • Develop, plan, conduct, and document results from complex experimental studies in clinical, forensic, or environmental toxicology.
  • Perform high-recovery sample preparation, including solid-phase extraction (SPE) of biological matrices such as urine, oral fluid, serum, or whole blood, for qualitative and quantitative analysis on LC-MS/MS platforms.
  • Analyze experimental data and author technical reports correlating findings to product, process, or assay performance.
  • Execute complex laboratory experiments in compliance with validated protocols, standard operating procedures (SOPs), and company guidelines; document project milestones through technical reports and experimental summaries.
  • Work on individual tasks and long-term project teams, and serve as a technical leader and advisor to Associate Scientists.
  • Identify experimental and analytical anomalies, investigate alternative methodologies, and recommend data-driven courses of action.
  • Maintain current knowledge of industry-relevant technological advancements and peer-reviewed scientific literature to optimize laboratory processes, workflows, or procedures.
  • Integrate and apply advanced analytical methods and next-generation instrumentation.
  • Contribute ideas and technical concepts for new product development, primarily targeting established clinical and diagnostic markets.
  • Safely handle infectious biological specimens and hazardous chemical waste in accordance with environmental health, safety, and corporate waste-disposal practices.
