Company Summary:

Tessera Therapeutics is pioneering Gene Writing™— a new biotechnology designed to offer scientists and clinicians the ability to write small and large therapeutic messages into the genome, thereby curing diseases at their source. Gene Writing holds the potential to become a new category in genetic medicine, building upon recent breakthroughs in gene therapy and gene editing while eliminating important limitations in their reach, utilization, and efficacy. Tessera Therapeutics was founded by Flagship Pioneering, a life sciences innovation enterprise that conceives, resources, and develops first-in-category companies to transform human health and sustainability.

Position Summary:

The Scientist will contribute to evaluation of genomic safety of pioneering gene writing technologies (RNA writers) and support the process of development of innovative therapeutics. In this role, the Scientist will be applying the knowledge in fundamental biology to investigate cellular responses to the genotoxic stress and help assess and improve the safety profile of RNA writers. We are searching for a self-motivated individual with a passion for science and enthusiasm for development of revolutionary therapeutics. The successful candidate will join a dynamic, rapidly growing, and highly collaborative team.

Key Responsibilities:

  • Use classic and cutting-edge molecular and cellular biology techniques to assess genomic stability and cell fitness/proliferation upon gene editing with RNA writers
  • Collaborate cross-functionally to characterize and optimize leading RNA writer candidates, advance our knowledge in RNA writer biology
  • Apply knowledge of molecular biology of the cell to address complex biological questions
  • Work in a team environment, meet the deadlines, and prioritize and balance work from multiple sources
  • Manage and train junior research associates

Basic Qualifications:

  • D. in biological sciences
  • Experience in culturing immortalized and primary mammalian cell lines and transfection techniques
