About the Role

As the Director of Immunoassay Development, you will lead the transformation of innovative assay concepts into robust, scalable, and regulatory-compliant diagnostic products that advance patient care. You’ll guide both the strategic vision and technical execution across the full product lifecycle—from early feasibility through design control, verification, validation, and seamless transfer to manufacturing. This role is ideal for a dynamic, hands-on leader who combines deep immunoassay expertise with a passion for mentoring teams, driving cross-functional collaboration, and shaping the future of diagnostic innovation.

Team Culture:

- Research Oriented 
- Problem Solvers 
- Detail Oriented
- Analytical
- Collaborative

What You Will Do

  • Lead the full immunoassay development lifecycle from early concept and feasibility to design transfer, verification, validation, and regulatory submission.
  • Transform scientific innovation into impact by translating early proof-of-concept studies into structured design inputs, specifications, and controlled development plans aligned with FDA, ISO 13485, and CE-IVD requirements.
  • Design and oversee meaningful experiments that generate high-quality data for regulatory submissions, ensuring traceability and alignment between design inputs, verification, and validation outcomes.
  • Collaborate seamlessly with Regulatory Affairs and Quality teams to ensure experimental design, documentation, and testing strategies meet FDA 21 CFR 820 and IVDR standards.
  • Partner cross-functionally with Manufacturing, Process Engineering, and Operations to refine assay transfer protocols that drive robustness, scalability, and cost-effectiveness in production.
  • Oversee design verification and validation (V&V) activities including method comparison, reproducibility, precision, interference, and stability studies — ensuring data integrity and regulatory readiness.
  • Drive design transfer to manufacturing, supporting process qualification, equipment validation, and training to enable smooth transition into production.
  • Mentor and empower a multidisciplinary team of scientists and engineers, fostering a culture rooted in collaboration, scientific rigor, and continuous learning.
  • Work strategically with Program Management to define project timelines, resource plans, and risk mitigation strategies that align with company milestones and product launch goals.
  • Review and approve technical documentation, design history files, verification reports, and regulatory submissions (e.g., 510(k), De Novo, CE-IVD) with a commitment to excellence and compliance.
  • Stay future-focused by keeping current with evolving FDA and IVDR guidance, and by evaluating emerging immunoassay technologies that strengthen innovation and competitiveness.

What You'll Need to Have

  • Ph.D. in Biochemistry, Immunology, Analytical Chemistry, or related discipline with a strong foundation in immunoassay principles.
  • 10+ years of industry experience in immunoassay or in vitro diagnostic (IVD) product development within a regulated design control environment.
  • Proven track record of translating benchtop assays (e.g., ELISA, CLIA, LFA, bead-based, or homogeneous immunoassays) into validated, manufacturable diagnostic products.
  • Comprehensive understanding of FDA 21 CFR 820, ISO 13485, IVDR, and design control processes — including risk management, verification, validation, and design transfer.
  • Demonstrated success in verification and validation planning, data analysis, and preparation of high-quality data packages for regulatory submissions.
  • Hands-on collaboration experience with manufacturing and process engineering teams to scale production and ensure consistency across lots.
  • Inclusive and results-oriented leadership style, with the ability to guide teams, balance priorities, and deliver products that meet technical and regulatory milestones.
  • Excellent communication and collaboration skills, with the ability to connect scientific, regulatory, and business goals across diverse teams and stakeholders.
