Job summary

This is an exciting opportunity for a well-qualified candidate to join a rapidly growing international company focused on transforming the lives of patients with rare disorders through innovative gene therapies.

Orchard Therapeutics, Ltd. (OTL) is looking for a suitable candidate to join the newly created analytical development team at Orchard. The candidate will perform activities related to the development and implementation of analytical methods for the testing, lot release and characterization of OTLs innovative gene-modified cell-based therapeutic products. More specifically, working in the lab, as well as with OTLs designated European Contract Manufacturing Organizations (CMOs) and Contract Testing Organizations (CTOs), this individual will be responsible for developing and/or optimizing new and existing analytical methods (in-house, in the lab and outsourced) to facilitate the progression of OTLs product pipeline programs.

Key Elements and Responsibilities
  • Work in the laboratory to develop and/or re-optimize new and existing analytical methods for the lot release and characterization of HSC-derived gene therapy products with specific cell-based potency assay development expertise.
  • Routine operation of potency assays and other analytical methods to support characterisation of HSC-derived gene therapy products as required.
  • Oversee analytical method development and optimization with external partners as required.
  • Execution, review and approval of method development reports, protocols and process documents as required.
  • Assist in the preparation of CMC regulatory submissions.
  • Assisting with comparability protocol design and execution as required
