We are seeking a Scientist or Senior Scientist to join our Translational Science/Bioanalysis Department, supporting bioanalytical PK, ADA, and related biomarker assays for clinical‑stage oncology programs using ELISA (Soft Max Pro) and MSD platforms. This role serves as a critical translational interface between nonclinical development and clinical trials, generating high-quality, GLP‑compliant bioanalytical data to support IND‑enabling studies and clinical development (Phase I–III).

The successful candidate will be responsible for PK and ADA assay development, validation, and execution, while ensuring full compliance with GLP, ICH, FDA, and global regulatory requirements.

• Design, develop, optimize, and execute PK, ADA, and related ligand‑binding assays (e.g., ELISA and MSD) to support nonclinical and clinical studies
• Perform routine and non‑routine bioanalytical sample analysis for toxicology and clinical trial samples in accordance with approved protocols and SOPs
• Ensure robust assay performance, including sensitivity, specificity, accuracy, precision, and stability

• Lead or support method qualification, validation, and partial validation in compliance with GLP
• Author, review, and maintain bioanalytical validation plans, reports, and SOPs
• Support technology transfer and method bridging to CROs or internal laboratories, including troubleshooting and performance assessment

• Conduct all laboratory activities in compliance with GLP, ICH M10, ICH E6, FDA Bioanalytical Method Validation Guidance, and internal quality systems
• Maintain audit‑ready documentation, ensuring data integrity, traceability, and compliance
• Support internal QA audits, external audits, and regulatory inspections (e.g., FDA, EMA, NMPA)
• Contribute to IND, CTA, and other regulatory submission documents related to bioanalysis and clinical pharmacology

• Collaborate with Translational Science, DMPK, Toxicology, Clinical Operations, and Regulatory Affairs teams to align bioanalytical strategy with clinical objectives
• Support exposure–response and PK/PD interpretation, and participate in translational data review meetings
• Provide bioanalytical input into clinical protocols, sample handling plans, and bioanalytical strategy documents

• Manage samples, reagents, and inventory using LIMS systems, ensuring proper chain‑of‑custody and documentation
• Maintain complete and accurate laboratory notebooks, data records, and analytical reports
• Troubleshoot assay issues and drive continuous improvement initiatives

• Mentor junior scientists and contribute to team capability development
• Stay current with emerging bioanalytical technologies, regulatory updates, and industry best practices
• Contribute to internal scientific reports, white papers, publications, or conference presentations as appropriate

• PhD in Pharmaceutical Sciences, Bioanalytical Chemistry, Biotechnology, Pharmacology, or a related discipline (MS with strong relevant industry experience may be considered)
• 2+ years (Scientist) or 5+ years (Senior Scientist) of industry experience in bioanalytical PK and/or ADA assays
• Hands‑on experience with ELISA, MSD, and ligand‑binding assay…
