About the role

Are you an inquisitive Process Engineer who enjoys practical laboratory work and has a passion to use digital tools and data analytics to make better process-development decisions? If so, this role could be for you! We are currently recruiting a Process Engineer to join our Drug Substance Development (DSD) team at GSK Stevenage R&D site. For candidates seeking to be located at our Stevenage site, this role will temporarily be based at Stevenage. However, the Company plans to relocate its offices to Ware. The location of this role will therefore subsequently change to Ware in accordance with timelines to be set by the Company. The relocation is currently proposed to take effect by early 2029 . As a member of DSD, you will apply your engineering knowledge to develop and deploy state-of-the-art processes and technologies that support the development and delivery of GSK medicines. This is a practical role based in R&D laboratories, where you will work alongside chemists and material scientists to build the process understanding needed for successful scale-up and commercial industrialisation of future GSK manufacturing processes. You will combine digital, data and analytics (DDA) information from laboratory studies with engineering principles, process simulation and modelling to develop robust, scalable and sustainable pharmaceutical manufacturing processes. As processes transfer to pilot-plant facilities for clinical-trial delivery or to manufacturing facilities for commercialisation, you will provide global support as the engineering technical expert. The work will focus primarily on chemistry-based small molecules and oligonucleotides, with potential involvement in biochemistry-based large molecules, vaccines and antibody-drug conjugates. In this role you will... • Design and conduct scale-up and scale-down experiments across chemical engineering unit operations, building process understanding within fast-paced project timelines. • Think creatively to optimise engineering solutions and de-risk scale-up processes. • Analyse experimental results and communicate conclusions and recommendations clearly at internal R&D meetings. • Contribute to technology-transfer activities with GSK manufacturing partners, providing engineering input appropriate to the project stage. • Use digital data and analytics alongside engineering expertise to predict and inform process-development decisions and manage scale-up risk • Author or contribute to internal documentation relevant to the role.  • Comply with applicable Data Integrity, Quality, cGMP (current Good Manufacturing Practice) and regulatory requirements in all aspects of work and fully embrace all aspects of safety when working in the laboratory. Why you? Basic Qualifications & Skills: We are looking for professionals with these required skills to achieve our goals: • BSc/BEng/Masters / PhD (or equivalent) in Process/Chemical Engineering. • Experience working in a plant and/or direct laboratory experience in the pharmaceutical industry, or related sector.   Preferred Qualifications & Skills The following skills and experiences are advantageous but not essential   • Practical familiarity with process simulation/modelling techniques such as DynoChem and similar software. • Experience collecting and interpreting digital process data, including through Process Analytical Technology (PAT), and using analytics to support timely decision-making. • Experience working effectively in a cross-functional scientific or engineering team. Closing Date for Applications – Wednesday 28th October 2026 Please take a copy of the Job Description, as this will not be available post closure of the advert.  When applying for this role, please use the ‘cover letter’ of the online application or y
