Job Description

We are seeking a Scientist with expertise in plate-based process impurity assays to support biologics programs. This role will focus on the development qualification troubleshooting and transfer of ELISA-based assays for detecting Host Cell Proteins (HCP) residual Protein A residual DNA and other process-related impurities. The ideal candidate will have hands-on experience in assay development and validation strong analytical problem-solving skills and the ability to collaborate with cross-functional teams.

Key Responsibilities:

1. Assay Development & Qualification (50%)

  • Develop optimize and qualify plate-based impurity assays (e.g. ELISA qPCR Western blot) for process impurity detection.
  • Evaluate assay performance ensuring sensitivity specificity accuracy and precision meet regulatory expectations.
  • Conduct method qualification and contribute to validation strategies in compliance with ICH and USP guidelines.
  • Support the development of custom and commercial HCP ELISAs including reagent assessment and selection.

2. Assay Troubleshooting & Remediation (30%)

  • Investigate assay variability drift and reagent stability issues to ensure robust impurity testing.
  • Work with internal teams and external vendors/CROs to assess critical reagents and optimize assay performance.
  • Provide technical expertise in resolving lot-to-lot variability issues in impurity assays.
  • Analyze and interpret assay data preparing technical summaries and reports.

3. Technology Transfer & Regulatory Support (20%)
