Role description:
As part of the Microbial Engineering Division, the fermentation assistant will work with the fermentation scientist
to provide day-to-day operations of Colorifix’s proprietary fermentation process at its R&D in Norwich, UK. The
fermentation suite comprises a series of lab-scale bioreactors used to characterise Colorifix’s engineered
microorganisms and produce dyeing liquor which will be applied on fabrics for small scale dyeing runs. This will
involve working closely with the synthetic biology team of the Microbial Engineering Division as well as with the
Colouration team, to coordinate work across the process. The fermentation assistant will be responsible for
preparing, running and collecting data from fermentation runs. They will also collect samples and carry out
analysis, along with subsequent data analysis and report writing, ensuring that batch records are maintained for all
runs. The fermentation assistant will be expected to contribute to the maintenance and efficient running of the
fermentation suite. They will be given responsibility for specific tasks and, after training, be expected to carry them
out independently e.g., media preparation, bioreactor prepping and cleaning, sampling, sample processing and
support in the data analysis. Longer-term there may be an opportunity to be trained in the use of HPLC equipment
and development of analytical methods.

Essential skills and experience:
● BSc in biological sciences or relevant work experience in a biological sciences discipline.
● An understanding of basic microbiology techniques (e.g., aseptic technique and bacterial culture growth).
● Basic experience in the use of conventional laboratory equipment (e.g., centrifuge, microscope,
spectrophotometer, pH meter).
● Good communicator and flexible team player that is committed to the success of the team as a whole.
● Ability to follow standard operating procedures and continuously improve operations in the laboratory.
● Good organisational skills. Practised in data analysis and report writing.
● 1-2 years experience in a lab based technical role.

Desirable skills and experience
● Previous experience using microorganisms in a fermentation process.
● An attention to detail for maintaining fermentation batch record sheets.
● Previous experience with analytical techniques and equipment (spectrophotometer, HPLC)
● Experience in troubleshooting and problem solving, for both long term and quick solutions
● Development of templates for data analysis.
● Experience of keeping a digital lab book.
● Experience of working in multi-disciplinary teams.
