We are looking for a hands-on Senior Scientist to join the Validation Team at IQVIA Labs. This is not a pure research role; it is a technical problem-solving role. You will be the "go-to" person when instrumentation fails or data looks abnormal, responsible for troubleshooting assays and ensuring the validity of analytical runs. You will support Method Validation for small molecule assays (LC-MS/MS), executing complex extractions from biological matrices and ensuring data integrity in a strictly regulated GLP environment. **What You’ll Be Doing:** + Serving as the technical lead for the Validation team, specifically focusing on troubleshooting assays and root cause analysis when instrumentation fails or data abnormalities occur. + Designing experiments and runs to support the validation of small molecule assays; you will focus on Method Validation and adaptation rather than pure Method Development. + Performing and documenting complex analytical procedures using LC-MS/MS, including extraction (Liquid-Liquid Extraction, Protein Precipitation) from biological matrices (plasma, serum, tissue) in a fast-paced environment. + Analyzing data, identifying deviations, and ensuring accurate upload to the LIMS system. You will be responsible for reviewing data from failed runs and proposing technical solutions. + Leading Quality Investigations and ensuring all work meets GLP regulatory standards. + Overseeing the technology transfer of methods and SOPs across departments to ensure scalability and sustainability. **What We’re Looking for:** + Bachelor’s degree in Chemistry, Biochemistry, or a related scientific discipline + 4+ years in a regulated lab (GLP preferred) with strong proficiency in LC-MS/MS operation and maintenance. + Deep familiarity with extracting small molecules (LLE, PPT) from biological matrices. + Strong practical knowledge of operating and troubleshooting LC-MS/MS and Mass Spec instrumentation. **Knowledge and Skills You’ll Need:** + A "troubleshooter" mindset; the ability to look beyond the result to diagnose the root cause (instrument vs. science) and propose independent solutions. + Excellent communication skills to effectively articulate complex data issues to cross-functional teams and ensure smooth method transfers + The ability to make data-driven decisions on run validity and experimental design independently + The resilience to work in a fast-paced, high-volume environment where priorities can shift quickly. + A natural orientation toward detail and precision IQVIA is a leading global provider of clinical research services, commercial insights and healthcare intelligence to the life sciences and healthcare industries.
