• Lead cross-functional teams to ensure research aligns with product development goals.
• Collaborate with suppliers to synthesize and characterize custom reagents.
• Troubleshoot technical challenges and ensure work complies with relevant standards.
• Oversee the transfer of reagents from R&D to manufacturing with appropriate QC procedures.
• Mentor research associates and contribute to the training of team members.

Qualifications

• Ph.D. or MS in Chemical Engineering, Biochemistry, Bioengineering, or a related field.
• 1-3 years of experience in IVD R&D for PhD; 8+ years for MS.
• Experience with allergen extraction, purification, and conjugation, as well as allergy-specific and autoimmunity IgG assays.
• Proficient in protein characterization (SDS-PAGE, Western blot, HPLC, FPLC) and purification techniques (IEX, SEC, affinity chromatography).
• Experience with immunoassay techniques is a plus.
• Strong background in experimental design, data analysis, and troubleshooting.
• Excellent communication and collaboration skills.

Preferred Skills

• Bio-conjugation experience, particularly with proteins, peptides, and nucleic acids.
• Experience developing life science reagents and working in an aseptic lab environment.
