Bioprocess Development & Manufacturing Scientist.

Drive & help manage process development & manufacturing activities and resources for Purespring’s products to ensure smooth and effective transition from pre-clinical & early phase clinical proof of concept to pivotal trials and commercial launch.

Purespring is one of the first AAV gene therapy companies focused on the kidney globally. It has been founded around the seminal work of Professor Moin Saleem, Head of Bristol Renal where he heads a world leading group researching glomerular diseases. Purespring will seek to advance gene therapies for the treatment of chronic renal diseases that are currently poorly addressed with existing treatments. The Company is backed by Syncona (, a London-listed FTSE 250 healthcare investment company founded by the Wellcome Trust.

We are building a world-class team from the ground up and are seeking an experienced Bioprocessing & Manufacturing professional to help drive the establishment, development and implementation of AAV production processes for both in-house and outsourced manufacture of AAV gene therapy products.

Experience of outsourced development & manufacturing in support of the GMP manufacture of biological products, spanning development through to Pivotal Phase III clinical material supply, is essential. Experience of commercial supply is desirable but not essential.

Experience of working with viral products is required. Experience of AAV and gene therapy products is preferable.

Many manufacturing activities are outsourced. Experience of managing out-sourced manufacture is therefore preferable.

This role will report to the VP Development.
