Walker Cole International are currently supporting the hire of an Upstream Fermentation Scientist for a leading biologics process development organisation supporting global pharmaceutical and biotechnology companies.

As an Upstream Fermentation Scientist, you will support the development, optimisation, scale-up, and technology transfer of microbial fermentation processes across a range of innovative biopharmaceutical programmes.

Key Responsibilities

• Develop, optimise, and scale microbial fermentation processes using bacterial, yeast, and fungal expression systems

• Design and execute fermentation studies, including media optimisation, process characterisation, growth parameter optimisation, and yield improvement activities

• Support scale-up activities from laboratory through to pilot-scale bioreactors and establish representative scale-down models

• Utilise Design of Experiments (DoE), statistical analysis, and process data to drive process understanding and optimisation

• Support technology transfer activities and ensure successful implementation of processes across development and manufacturing environments

• Collaborate closely with downstream processing, analytical development, strain engineering, and manufacturing teams to deliver integrated bioprocess solutions

• Troubleshoot process challenges and identify opportunities to improve process robustness, productivity, and scalability

• Provide technical leadership within project teams and support the development of junior scientists where appropriate

Knowledge, Skills & Experience

• MSc or PhD in Biotechnology, Microbiology, Biochemical Engineering, Bioprocess Engineering, Bioengineering, Biochemistry, or a related scientific discipline

• Significant industrial or academic experience in microbial fermentation, upstream process development, or industrial biotechnology

• Hands-on experience operating bioreactors across laboratory, bench, and pilot scales

• Strong understanding of batch, fed-batch, and continuous fermentation processes

• Experience with fermentation process optimisation, media development, scale-up, and process troubleshooting

• Knowledge of bioprocess data analysis, DoE, statistical modelling, and process characterisation techniques

• Experience supporting technology transfer, process development, or manufacturing activities would be advantageous

• Strong communication, problem-solving, and stakeholder management skills

This opportunity would suit an Upstream Fermentation Scientist, Fermentation Scientist, Upstream Process Development Scientist, Bioprocess Scientist, Microbial Fermentation Scientist, or Bioprocess Development Scientist looking to further their career within biologics process development.

Where to Advertise Biotech Jobs in the UK (2026 Guide)

Where to advertise biotech jobs UK in 2026: the specialist boards, academic networks and trade channels that reach biotech R&D and bioprocessing talent. The candidate pool spans life scientists, computational biologists, regulatory specialists and biomanufacturing engineers — each with distinct professional networks and job search behaviours. General job boards reach a broad audience but lack the specificity that biotech professionals expect. Specialist platforms, academic channels and sector-specific communities each serve a different part of the market. This guide, published by BiotechnologyJobs.co.uk, covers where to advertise biotech roles in the UK in 2026, how the main platforms compare, what employers should expect to pay, and what the data says about hiring across different role types.

Biotech Jobs UK 2026: What to Expect Over the Next 3 Years

Biotech Jobs UK 2026: roles, salaries and the genomics, cell therapy and AI-driven drug discovery hiring trends shaping UK biotech careers. Biotechnology is creating jobs at a rate that few other sectors can match. New disciplines are emerging from research labs and entering commercial hiring pipelines, existing roles are fragmenting into deeper specialisms, and the technologies driving it all — from AI-assisted drug discovery to next-generation gene editing — are advancing faster than the workforce can keep pace with. For job seekers, this creates an unusual challenge. In most industries, career planning means navigating a relatively familiar landscape and identifying where your skills fit. In biotech, that landscape is being actively redrawn. The roles generating the most hiring activity in 2028 may look quite different from the ones appearing in job adverts today. That's not a reason to feel overwhelmed — it's a reason to get informed. The candidates who thrive in this market aren't always those with the longest CVs or the most letters after their name. They're the ones who understand where the sector is heading: which disciplines are gaining commercial traction, which technologies are driving employer demand, and how the definition of a "biotech job" is expanding well beyond traditional pharmaceuticals and research roles. This article breaks down what the UK biotech jobs market is likely to look like over the next three years — covering emerging job titles, the technologies reshaping hiring, the skills employers are prioritising right now, and how to position your career ahead of the curve rather than behind it.
