Bioprocess Engineer

Designs and runs the processes that use living cells to make products such as vaccines, antibodies, enzymes and biofuels at scale.

Bioprocess engineers work for biopharmaceutical and vaccine makers, food and brewing companies, and biofuel and enzyme producers, linking lab science with manufacturing. It suits people who like biology and maths together and enjoy solving practical problems.

Also called Biochemical engineer, Process engineer, Process development engineer or Bioprocess scientist.

The work

What does a bioprocess engineer do?

  • Develop and optimise cell culture and fermentation steps in the lab and pilot plant.
  • Scale processes up from small bioreactors to full production while keeping the product consistent.
  • Design purification steps such as filtration and chromatography to recover the product.
  • Monitor production runs and find out why a batch has gone wrong when it does.
  • Write procedures and reports that meet good manufacturing practice and regulators' rules.

Where they work

  • Biopharmaceutical manufacturers
  • Vaccine production sites
  • Brewing and food companies
  • Biofuel and enzyme plants
  • Contract manufacturing organisations

How to become a bioprocess engineer

  1. Take maths and chemistry at school, with biology or physics if you can.
  2. Complete a degree in chemical, biochemical or bioprocess engineering, ideally with an industrial placement year.
  3. Join a graduate scheme or a process development team at a biomanufacturing company.
  4. Work towards chartered engineer status, or take a master's or PhD for research-heavy roles.

Degrees people take

  • Chemical engineering
  • Biochemical engineering
  • Bioprocess engineering
  • Biotechnology

In the UK, IChemE (the Institution of Chemical Engineers) accredits degrees, biochemical engineering among them, and you can become chartered through it.
