We are seeking an experienced and highly motivated Sr. Director, Assay Development to drive continued growth and expansion of our portfolio of ultrasensitive Simoa immunoassays into IVD validation. This is a high impact role with responsibility for leading development of clinically and commercially significant Simoa biomarker assays. You will use your technical and managerial skills and experience to lead a high-performing group of Assay Development scientists and to oversee multiple immunoassay development projects for novel biomarkers serving fast-growing market segments.

BASIC QUALIFICATIONS

• Ph.D. in Biology, Biochemistry, or other relevant life science discipline such as Immunology.
• 10+ years of immunoassay development experience in an industrial diagnostic R&D setting (IVD/Diagnostics), including design, development, and verification/validation activities supporting commercialization.
• 5+ years of experience managing people and leading immunoassay development projects
• Demonstrated experience working with established standards related to the development and validation of biomarker assays, including CLSI guidelines, fit-for-purpose biomarker method validation, ISO9001, ISO13485, and FDA data reporting requirements.

PREFERRED QUALIFICATIONS

• Experience supporting regulated IVD products under EU IVDR and/or FDA frameworks, including partnering with RA/QA on technical documentation (e.g., performance evaluation/validation evidence) and requirements to enable CE marking and market access
• Experience of successfully leading development of products within a stage-gate process is required.
• Familiarity with the field of protein biomarkers for neurodegeneration, infectious disease, or cancer is strongly preferred.

EXPECTATIONS, COMPETENCIES, SKILLS & ABILITIES

• Broad subject matter expertise in key technical aspects of commercial immunoassay development, including protein chemistry, antibody screening, antibody: bead conjugation, assay diluent formulation, multiplexing, preanalytical sample processing, scale-up, assay optimization, troubleshooting, multivariate data analysis, and analytical and clinical validation.
