Temporary Biomedical Scientist jobs

Join our R&D Laboratory Services team in Slough to deliver vital mammalian cell culture, recombinant protein production, and bioreactor operations that directly enable the development of innovative, life-saving biopharmaceuticals on a 12-month contract.

This is a fully site‑based role. Working together in person supports close, real‑time collaboration and the technical precision needed to manufacture medicines to the highest quality and safety standards.

What you will get:

• An agile career and dynamic working culture.

• An inclusive and ethical workplace.

• Competitive hourly rate.

The hourly rate for this position in the United Kingdom is expected to range between £17.00 and £20.00. Initial salary placement within this range will be determined based on role‑related factors such as experience, qualifications, and expected contribution.

What you will do:

• Conduct routine upstream bioprocess experiments strictly following established Standard Operating Procedures (SOPs).

• Perform daily aseptic CHO mammalian cell culture passaging, media preparation, and cell viability tracking.

• Set up, inoculate, sample, and monitor bench-scale automated bioreactor runs (ambr15, ambr250) for recombinant protein production.

• Record, analyze, and document experimental data accurately using MS Office and digital laboratory tools.

• Maintain laboratory equipment, assist with instrument calibrations, and manage technical reagent and consumable inventory.

• Collaborate closely with cross-functional team members across R&D and Manufacturing pipelines.

• Adhere strictly to Good Laboratory Practice (GLP) standards and site Health & Safety guidelines.

What we are looking for:

• Direct hands-on experience with CHO mammalian cell culture maintenance and aseptic handling techniques.

• Demonstrated experience working with recombinant proteins or monoclonal antibodies in a laboratory environment.

• Practical operational experience with bench-scale bioreactors (such as ambr15, ambr250, or similar bioreactor platforms).

• Proven ability to perform experimental workflows to GLP standards and follow SOPs accurately.

• Strong proficiency in Microsoft Office suite and scientific data logging.

• Background in a Biotech, Pharma, or CDMO environment is highly desirable.

• Proactive work ethic with strong collaborative and multi-tasking abilities.
