About the Role The Senior Mass Spectrometry Scientist will lead the design, development, validation, and production deployment of targeted quantitative LC‑MS/MS assays for metabolites and small molecules, which constitute approximately 80% of the role. Working primarily on triple‑quadrupole platforms, the scientist will build robust, high‑throughput quantitative methods for a broad range of analytes — including amino acids, organic acids, fatty acids, bile acids, vitamins, steroids and hormones, and other clinically relevant metabolites — across diverse biological matrices. A core expectation of this role is taking assays from R&D through analytical and clinical validation and into the production / manufacturing pipeline of a high‑complexity clinical laboratory. The remaining ~20% of the role supports targeted proteomic and peptide quantitation on high‑resolution platforms as part of the company’s multi‑omics testing portfolio. The scientist will collaborate cross‑functionally with R&D, bioinformatics, automation, quality assurance, and clinical operations teams to advance projects from concept to live, patient‑impacting te Responsibilities Metabolomics & Small‑Molecule Assay Development (≈80%) Develop, optimize, and validate targeted quantitative LC‑MS/MS methods (MRM/SRM) for metabolites and small molecules across matrices such as plasma, serum, urine, and other biofluids. Design quantitation strategies using stable isotope‑labeled internal standards, calibration curves, and robust QC schemes to achieve accurate, precise, and reproducible measurements. Develop and optimize sample‑preparation workflows (protein precipitation, solid‑phase extraction, liquid‑liquid extraction, derivatization) using both manual and automated / liquid‑handling platforms. Develop chromatographic separations (reversed‑phase, HILIC) suited to chemically diverse small‑molecule analytes. Lead the transfer of validated assays into the production / manufacturing line, partnering with operations and automation teams to ensure throughput, robustness, and long‑term reproducibility. Perform analytical and clinical method validation (accuracy, precision, linearity, LOD/LOQ, matrix effects, carryover, stability, reference intervals) in accordance with CLIA/CAP and applicable regulatory standards. Support the development and execution of targeted proteomic / peptide assays (e.g., PRM, stable isotope dilution) on high‑resolution Orbitrap and LC systems for multi‑omics panels. Contribute to peptide mapping, post‑translational modification (PTM) analysis, and intact / protein‑level measurements as needed. Operate, maintain, calibrate, and troubleshoot triple‑quadrupole LC‑MS/MS systems (e.g., Sciex, Agilent, Waters) and associated UHPLC; work with high‑resolution Orbitrap platforms for confirmation and proteomic applications. Perform routine performance checks, system suitability testing, and preventive maintenance to ensure data quality in a regulated environment. Coordinate with vendors to implement upgrades, new applications, and service support. Data Analysis & Bioinformatics Process and interpret quantitative MS data using vendor and specialized software (e.g., Sciex OS / MultiQuant, Agilent MassHunter Quantitative, Waters TargetLynx, Thermo TraceFinder, Skyline). Integrate metabolomics data with proteomics, genomics, and other omics layers to generate multi‑dimensional, clinically meaningful insights. Collaborate with bioinformatics teams to refine quantitation pipelines, perform statistical analyses, and support clinically relevant reporting. Research & Development Lead biomarker and assay development efforts and translate findings into validated clinical tests.Explore applications across metabolic, cardiovascular, endocrine, oncologic, neurologic, and immunologic health. Stay current with literature, emerging technologies, and regulatory trends in metabolomics, small‑molecule quantitation, and clinical mass spectrometry. Motivated problem solver with strong attention to detail, excellent organizational and time‑management skills, and the ability to manage multiple projects to meet development timelines in a collaborative, team‑oriented environment Qualifications Proven production / clinical implementation: Demonstrated, hands‑on experience developing an assay or product that was successfully implemented and is actively running in a production or manufacturing pipeline in a clinical diagnostic (CLIA/CAP) laboratory setting. This is a firm requirement for the role. PhD in Analytical Chemistry, Biochemistry, Chemistry, Chemical Biology, Biology, or a related field with 5+ years of relevant experience, or an MS with 10+ years of experience, in mass spectrometry‑based metabolomics and/or small‑molecule quantitation in an industry, biotech, or clinical la boratory setting.Hands‑on expertise in targ eted quantitative LC‑MS/MS method development and execution on triple‑quadrupole instruments, includi ng MRM/SRM assays using stable isotope‑labeled in ternal standards. Hands‑on experience operating, maintaining, and troubleshooting triple‑quadrupole MS and UHPLC systems; experience with high‑re solution Orbitrap instruments is a strong plus. Demonstrated experience developing and optimizing sample‑preparation methods from a va r iety of matrices (plasma, serum, urine, biofluids), including automated / liquid‑handling workflows. Experience with analytical and clinical assay validation (CLIA/CAP), including accuracy, precision, linearity, sensitivity, matrix effects, carryover, and stability.Proficiency analyzing and interpreting quantitative MS data using software such as MultiQuant, MassHunter, TargetLynx, TraceFin der, or Skyline, and the ability to communicate results effectively in a fast‑paced, team‑oriented environment. Familiarity with targeted proteomics / peptide quantitatio n (PRM, DIA/DDA) and high‑resolution MS is desirable and supports the proteomics component of the role. Experience with un‑targeted / discovery metabolomics on high‑resolution platforms (e.g., Compound Discoverer, XCMS, MZmine) is desirable. Please Note: This is a laboratory‑based role with routine handling of biological and chemical samples. It requires extended periods at mass spectrometry instruments and computational workstations. Occasional weekend / evening work may be required for long LC‑MS runs or instrument troubleshooting. #J-18808-Ljbffr Vibrant Wellness
