Bio-Process Engineer (Downstream)

HIGH DemandMEDIUM AI RiskGROWING in SL· Rs.160k+ /mo

About This Role

Specializes in the recovery and purification of biological products from complex mixtures after fermentation.

A Day in the Life

Bio-Process Engineers specialising in downstream processing focus on the separation, purification, and formulation of biological products after the bioreactor stage — handling centrifugation, chromatography, filtration, and fill-finish operations.

  • Develop and optimise chromatography purification methods (affinity, ion exchange, size exclusion)
  • Design and operate tangential flow filtration (TFF) and depth filtration steps
  • Monitor product purity and yield at each downstream processing step
  • Perform viral inactivation and removal studies as part of biosafety validation
  • Write and execute downstream process validation protocols
  • Collaborate with upstream teams on process integration and product handoff specifications
  • Troubleshoot purification step failures and investigate yield losses
  • Prepare batch records and technical reports for regulatory submission
