Job Title: IVD Assay Characterization Validation Consultant Job Description

We are seeking an IVD Assay Characterization Validation Consultant to lead the technical characterization, execution, analytical verification, and regulatory documentation for automated clinical chemistry processes. This role requires a hands-on scientist with a proven track record of transforming complex biochemical processes into scalable manufactured diagnostic products. The successful candidate will spearhead CLSI-compliant validation protocols, manage analyzer operations, lead multi-method matrix characterizations, and author technical packages for FDA Pre-Submissions Q-Sub.

• Author, review, and finalize formal clinical validation protocols in strict alignment with CLSI guidelines.
• Establish analytical and clinical acceptance criteria for non-standard, altered, or synthetic matrix applications.
• Design iterative experimental workflows to characterize precision, linearity, interferents, stability, and matrix dynamics.
• Lead hands-on operation, calibration, and execution on automated clinical chemistry platforms, specifically Roche Cobas systems.
• Perform complex multi-day evaluations, such as 20-day EP05 protocols, spike-and-recovery assessments, and serial dilution series.
• Mentor and train laboratory staff on platform SOPs, clinical protocols, and standardized analytical techniques.
• Spearhead method comparison studies evaluating candidate assays against primary and secondary reference standards.
• Investigate and resolve complex matrix phenomena, such as surface tension variations, fluidic behavior, and recovery bias in protein-free aqueous solutions.
• Conduct iterative assay characterization cycles to define Limits of Detection/Quantitation (LoD/LoQ) and Analytical Measuring Ranges (AMR).
• Perform statistical analysis on raw datasets using specialized validation software to build statistical models, recovery plots, and bias metrics.
• Draft comprehensive Method Validation Reports (MVRs) for inclusion in the Design History File (DHF) and regulatory filings.
• Compile analytical performance packages for FDA Pre-Submission Q-Sub documentation.
• Frame strategic technical and regulatory questions for FDA Q-Sub interactions regarding matrix expansion and validation scope.

• On-going Ph.D. or Ph.D. in Clinical Chemistry, Biochemistry, Biomedical Engineering, or a related discipline.
• 2 years of experience in IVD assay development, characterization, and method validation within a regulated quality environment (FDA 21 CFR 820 / ISO).
• Deep practical knowledge of CLSI standard methodologies.
• Direct hands-on experience operating automated clinical chemistry analyzers; Roche Cobas experience strongly preferred.
• Working knowledge of FDA 510k matrix expansion strategies and the Q-Sub process.

• Demonstrated ability to bridge theoretical chemistry and commercial IVD manufacturing requirements.
• Strong practical troubleshooting capability on benchtop and automated platforms.
• Exceptional experimental discipline, data integrity, and attention to detail.
• Ability to distill complex analytical findings into actionable insights for scientific, engineering, and regulatory teams.
• Self-directed operator who thrives in a fast-paced, milestone-driven product development environment.

The role offers a flexible consulting/contract arrangement with a hybrid schedule, including three days on-site and two days remote, based in Indianapolis, IN. The work environment is dynamic, focusing on a large-scale commercial point-of-care IVD product launch.
