Successful Pharmaceutical Company Seeks Associate Scientist / Research Scientist

A successful pharmaceutical company is looking for an Associate Scientist / Research Scientist to join its Drug Substance Process Sciences team and support the development of innovative biologics.

This is a hands-on laboratory role focused on upstream process development, optimisation and characterisation, with exposure to mammalian cell culture, high-throughput platforms and bioreactor systems from microscale through to pilot scale.

Key Responsibilities

  • Design and execute upstream process development studies.
  • Develop and optimise mammalian/CHO cell culture processes.
  • Operate shake flasks, Ambr® systems and laboratory-scale bioreactors.
  • Apply DoE and QbD approaches to process optimisation and characterisation.
  • Support scale-up, troubleshooting, technology transfer and manufacturing activities.
  • Analyse experimental data and communicate findings through reports and presentations.
  • Collaborate with Cell Line Development, Analytical Sciences, Downstream Development and Manufacturing teams.
  • Maintain high standards of GMP, data integrity, HSE and laboratory compliance.

Reasons to use Rodeo

I’m in my final year doing Economics and I don’t know whether to apply for grad schemes now or do a masters first. What do you think?

Honest answer — it depends on where you want to end up. A lot of top grad schemes (Big 4, civil service, banking) don’t need a masters. Let’s look at the ones you’d be competitive for now, and we can decide if a masters actually adds anything.

Also worth knowing: most autumn 2026 applications are open now. Timing matters more than you think.

Start with a chat, not a search bar

Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
