Job Description

Principal Scientist – Gene Therapy

Full-time role: 37.5 hours per week over the course of 5 days.


Pencil Biosciences i s a seed stage biotech company developing the novel Break Free TM gene editing platform. The proprietary gene editor offers unique platform properties including an unparalleled safety profile with applications in therapeutics, diagnostics, and cell engineering.


Pencil is developing an in vivo gene editing therapeutics program and as an experienced cell biologist you will be expected to facilitate the transition from proof of concept in mammalian cells lines into the primary cell. You will also be expected to run tests to support the pre-clinical model work in relation to payload formulation and analyse cargo delivery into cells and cellular organelles.


This is a key role for the company in applying the technology in the target organs. It is an on-site hands-on technical role where extensive experience is required. The role will sit within an experience team of gene editors, molecular biologists and protein engineers, and will require a can-do attitude and adept communication across different disciplines. It also requires process development and ability to transfer knowledge to internal and external teams. First-hand gene editing experience is required but does not need to be extensive at this stage.


You will drive forward such activities as:

  • Cell biology: in various cell lines and types; include that of hepatocytes and lymphocytes
  • Primary cell and tissue : including the culturing of cells from human, primate, and mouse primary tissues
  • Protocol development : biochemical assays and assessment of delivery cargos for key primary cell types
  • In vivo model lead: Lead or support outsourced pre-clinical model work for both healthy and disease models
  • Technology evaluations: Lead the Developing assays for external technology evaluations for assessment with 3 rd party partners
