Own the IVD reagent development plan execution by developing reagent specifications and manufacturing processes for finished reagents that will be used for DELFI’s molecular diagnostic assays.

Lead the Reagent Development and Operations team and be accountable for Process Validation and Design Transfer from R&D to Operations.

Define reagent criticality (Key, Ancillary, General Use) for DELFI's IVD molecular diagnostic assays, and develop reagent FMEA to inform testing rigor and change control requirements.

Develop and qualify QC test methods for reagent lot release, including method design, acceptance criteria, lot release procedures, and integration with batch manufacturing records.

Evaluate Contract Reagent Manufacturers. Be the primary point of contact and be accountable for the completion of process development and the generation of pilot builds for R&D needs by developing various scopes of work (SOWs) and helping implement supplier agreements. Participate in Quality audits.

Plan reagent stability to set preliminary expiry specifications required for Verification and Validation activities.

Perform rigorous design of experiment, data analysis, and act as subject matter expert by collaborating with assay biostatisticians, bioinformaticians, engineers, and scientists.

Develop IVD design documents required for PMA submission under Design Control to meet product development and project milestones.
