DEL Platform Scientist II

DNA ‑ encoded library (DEL) and SELEX (Systematic Evolution of Ligands by EXponential enrichment) technologies are rapidly expanding drug discovery platforms within the IVBU at WuXi AppTec. These multidisciplinary platforms integrate chemistry, chemical biology, molecular biology, and informatics to enable the discovery of novel binders and lead compounds.

We are seeking a motivated and technically strong Scientist II to join our DEL/SELEX screening team. The successful candidate will work closely with senior scientists and cross ‑ functional teams to execute high ‑ quality DEL and SELEX screening projects, analyze data, and support timely delivery of results to internal teams and external clients.

Responsibilities

• Execute DEL and/or SELEX screening experiments, including sample processing and downstream analysis, under the guidance of senior scientists or project leads.
• Support assigned DEL/SELEX projects by contributing to experimental planning, execution, troubleshooting, and documentation.
• Analyze screening data and assist in the preparation of technical reports and project summaries.
• Participate in internal technical discussions and project meetings; support client communications as needed.
• Contribute to internal DEL/SELEX research and development activities aimed at improving screening workflows and platform performance.
• Maintain accurate experimental records and ensure compliance with company standards and safety guidelines.
• Perform additional duties as assigned.
  
  

Qualifications

Experience / Education

• Master’s or Ph.D. degree in biochemistry, molecular biology, biotechnology, chemical biology, or a related field (or equivalent experience).
• 1–3 years of relevant industry experience, or a combination of industry and advanced academic research experience, in DEL, SELEX, or related affinity-based selection technologies.
• Demonstrated hands on experience in several of the following areas:
• Affinity based selection technologies (e.g., DEL, SELEX, mRNA display)
• Molecular biology techniques (e.g., molecular cloning, PCR, qPCR, gel electrophoresis)
