• Develop and optimize formulations, processes, and analytical methods.
• Interpret data (including cell culture performance) and translate results into actionable recommendations.
• Hands-on experimental work involving the characterization of material properties, set up, operation, and maintenance of bioreactors across batches, fed-batch, and perfusion modes (ATF/TFF).
• Process development work in the laboratory involving testing equipment, chemical processes, and testing materials and products (membranes, filters, polymers, etc.) inclusive of mammalian suspension cell work (CHO and HEK293 lines using both 2D and 3D culture systems.
• Carry out filter testing, failure analysis, lifetime studies, comparative performance evaluations using appropriate instrumentation that may involve chemical analysis, microscopy, thermal and mechanical properties evaluation.
• Operate both singleuse and glass bioreactor systems and associated equipment (controllers, pumps, perfusion setups, hollow fiber filters).
• Lead small-scale R&D projects or technical workstreams, including resource planning and coordination.
• Prepare detailed technical documentation, including protocols, reports, and presentations.
• Maintain documentation and support SOP development as we build out upstream lab capabilities.
• Collaborate with cross-functional teams (Engineering, Production. MTS) to support product development scale-up.
• Stay current with relevant scientific literature, technologies, and competitive trends.
• Mentor junior scientists and research associates as needed.
• Ensure compliance with all safety, quality, and regulatory standards.
