This hands-on, laboratory-based role requires strong problem-solving skills, a collaborative mindset, and flexibility in scheduling to accommodate experimental needs, including occasional weekend work.

Responsibilities

• Plan and execute downstream process development experiments for advanced therapeutic modalities, including AAV, LVV, and EV.
• Develop, optimize, and troubleshoot purification processes, including clarification, depth filtration, tangential flow filtration (TFF), and chromatography.
• Support the development and evaluation of continuous and intensified downstream processing technologies.
• Perform laboratory experiments to evaluate process parameters and improve product recovery, purity, yield, and quality.
• Operate, maintain, and troubleshoot downstream processing equipment, including AKTA chromatography systems and TFF systems.
• Collect, analyze, and interpret experimental data, document results, and communicate findings to the project team.
• Prepare technical reports, experimental protocols, and standard operating procedures (SOPs).
• Collaborate with upstream process development, analytical development, and manufacturing teams to support project objectives and technology transfer.
• Maintain accurate laboratory records and ensure compliance with established safety and quality procedures.
• Support laboratory operations, including equipment maintenance, inventory management, and preparation of buffers and solutions.
• Demonstrate flexibility in scheduling to support experimental activities, including occasional weekend work.
  
  
  

Education

• Bachelor’s degree in biology, Bioengineering, Biotechnology, Chemical Engineering, or a related scientific discipline with 6 years of relevant experience, or a master’s degree with 4 years of relevant experience.
