• Experience in lung sampling (bronchoalveolar lavage) is a plus

• Hands on execution of various in vitro and ex vivo wet lab activities such as aseptic technique, formulations preparation, bacterial culture, tissue and blood sample processing

• Logistical coordination of studies: scheduling support staff, arranging formulation pickup and sample drop off

• Optimize efficiency and productivity through effective management of workflow

• Help develop and validate new animal models of disease related to drug discovery programs and projects with the ability to adapt, learn, and master new or more complicated in vivo techniques

• Have a good acumen for running in vivo studies, timely production of quality data and accurate record keeping of experimental designs, protocols, and findings

• Demonstrate strong aptitude, initiative, and a high level of scientific curiosity to work collaboratively across multi-disciplinary teams, ensuring timely communication and delivery of high-quality in vivo data to Therapeutic Area program teams

• Remain compliant with all company required trainings and safety regulations

• Some off-hours and weekend work may be required

Education Requirement:

• Bachelor’s degree in Biological Sciences + 4 years relevant in vivo research experience, or Master’s degree in Biological Sciences + 2 years relevant in vivo research experience, or PhD in Biological Sciences
