Position Description

The Scientist I/II will work with Tr1X’s Virology/Molecular Biology team to design and execute studies in cell lines and primary immune cells to characterize candidate viral vectors and processes to support pipeline program advancement. This role offers exposure to company leadership, prime mentoring and scientific training, and an opportunity to be a high-impact contributor to the company’s mission and vision. The successful candidate will have demonstrable expertise in molecular cloning, lentiviral vector design and production and the design and execution of gene editing experiments in primary immune cells. 

The Impact You’ll Make

  • Design and produce viral vector plasmids and stocks in support of program goals.
  • Perform experiments in cell culture and primary cells to verify and optimize viral vector performance and gene editing protocols.
  • Maintain detailed and highly organized documentation of experimental procedures, data, and generated products.
  • Analyze data in a timely manner and present findings at team/departmental meetings.
  • Demonstrate advanced knowledge of principles and techniques in molecular cloning, cell culture, lentiviral vector biology and viral vector production
  • Keep up to date - on industry knowledge and advancements; provide input on optimization of design, process, or capability.
  • Contribute – Be a subject matter expert and contribute to project direction, prioritization and mitigation strategies.
  • Mentor junior Research Associates to help them reach the next level
  • Collaborate - and work effectively with Discovery Biology, Translational Sciences and CMC teams.

The Team – Yes You Belong!

We are building a diverse, bold, agile, and collaborative organization where each team member works closely and communicates respectfully with each other.
