Cell Culture Technician

Science is an early stage company developing technologies for a range of serious unmet medical needs. We are unafraid to take difficult technical risks, secure in the knowledge that with a clear understanding of what we are doing and with support from powerful modern tools, more progress is possible than might be immediately obvious. Regardless of role or team, the two most important factors we look for in a candidate are evidence of exceptional ability and the addition of positive energy to the group.

As a small, very early stage team in a largely unstructured environment, the ability to independently orient yourself to the problems that need to be solved and then follow through is essential.

We are seeking a strongly motivated Cell Culture Technician to join our team. The successful candidate will play a critical role in the operation of our Stem Cell Foundry, which produces high quality induced pluripotent stem cell lines. This job will entail ensuring operational excellence of stem cell culture including but not limited to: clonal selection and expansion, cell bank generation, and differentiation.

In addition, the candidate will perform quality control assays to characterize stem cell lines including testing for endotoxins, mycoplasma, sterility, and more. Science relies heavily on automation, and this role will involve leveraging that laboratory automation to achieve results beyond what you thought possible. This job is perfect for experienced cell culturists and molecular biologists with strong attention to detail and organizational skills looking to make an impact at an early stage of our company’s development.
