Scientist I – Analytical (Biologics)
Darlington (National Biologics Manufacturing Centre) | On-site | £26,939 – £36,939

About the Role
CPI is seeking an Analytical Scientist to join our growing Analytical team in Darlington, supporting a wide range of biologics process development programmes.

This role sits at the heart of how CPI delivers high-quality data to support bioprocessing, with work spanning molecule characterisation, product quality testing, and formulation/stability studies.

You will work across a diverse project portfolio – from early-stage development through to more advanced programmes – contributing to the characterisation and understanding of complex biologic products.
We are open to candidates from a range of analytical backgrounds, including those looking to transition from small molecules into biologics.

What You'll Be Responsible For

Analytical Testing & Characterisation

• Perform analytical studies to support process development and product characterisation
• Investigate:
  • Product quality and structural characteristics
  • Residuals and impurities (e.g. host cell proteins, DNA, endotoxins)
  • Stability and degradation pathways

Techniques & Methods

• Apply a wide range of analytical techniques, which may include:
  • Chromatography (HPLC/UPLC)
  • Mass spectrometry
  • ELISA and qPCR/ddPCR
  • Capillary electrophoresis and SDS-PAGE
• Contribute to biophysical analysis including:
  • Circular dichroism
  • Dynamic light scattering
  • Differential scanning calorimetry
  • Other structure/function techniques

Method Development & Data Analysis

• Support development and optimisation of analytical methods
• Analyse and interpret data, preparing clear reports and summaries
• Contribute to data trending, documentation, and ensuring data integrity

Project & Team Collaboration

• Work closely with upstream and downstream process development teams
• Contribute to delivery of multiple analytical work packages across projects
• Support continuous improvement of analytical workflows and lab practices

About You
You are an analytical scientist or early-career researcher with experience in laboratory-based analytical techniques and an interest in biologics.

You'll bring:

• A degree (or equivalent) in a scientific discipline (e.g. chemistry, biochemistry, molecular biology)
• Hands-on experience with analytical techniques
• Strong attention to detail and ability to generate high-quality data
• Good communication skills and ability to work in a team environment

Desirable (but not essential):

• Experience working with biologics or bioprocessing systems
• Exposure to biophysical characterisation techniques (e.g. CD, DLS, DSC)
• Experience with mass spectrometry or spectroscopy methods (e.g. IR, Raman)
• Experience with molecular biology techniques (e.g. qPCR, ELISA)
• Background in:
  • Analytical chemistry (including those looking to move into biologics)
  • Biochemistry or molecular biology

This role is ideal for someone who:

• Enjoys working across a variety of analytical methods
• Is curious and keen to broaden their technical skillset
• Wants exposure to cutting-edge biologics development

Why Join CPI?

• Work on diverse and impactful biologics programmes
• Gain exposure to a wide range of analytical and biophysical techniques
• Excellent environment for technical development and career progression
• Collaborative, multidisciplinary scientific teams
• Competitive salary (£26.9k-£36.9k)

Location & Working Pattern

• Based on-site in Darlington (NBMC, Nigel Perry Building)
• Laboratory-based role with hands-on experimental work

The Opportunity
This is a fantastic opportunity to join a highly capable analytical team and build experience across multiple technologies, modalities, and projects – making it ideal for someone looking to develop a strong, well-rounded analytical career in biologics.

Unfortunately this role doesn't offer sponsorship so we will not be accepting any applications for candidates who require this long term.
