• Design and synthesize peptides using solid-phase peptide synthesis (SPPS) techniques, using both automated peptide synthesisers and manual methods.
• Cleavage of peptides from resin supports, purification by preparative HPLC and analysis using mass spectrometry techniques.
• Identify, troubleshoot and help resolve synthetic and analytical challenges.
• Document experimental work accurately and in a timely manner, maintaining appropriate records in line with company standards.
• Communicate results clearly through presentations, data summaries, reports and discussion with colleagues and project team members.
• Contribute to multi-disciplinary research and drug development and collaborate effectively within matrix teams, building productive working relationships.
• Maintain and develop scientific knowledge by keeping up to date with literature, methodologies and advances in peptide chemistry and related disciplines. 

Essential experience/skills required:

• Undergraduate qualification (or equivalent level of experience) in Chemistry, Biochemistry or relevant subject area.
• Good understanding of chemistry and peptide chemistry, with the ability to apply scientific principles, concepts and techniques in a defined area.
• Technical proficiency in solid-phase and/or peptide synthesis via manual syntheses or automated peptide synthesisers.
• Working knowledge of HPLC purification and mass spectrometry.
• Excellent record-keeping and strong written and verbal communication skills.
• Experience of working within a team environment and developing good working relationships with individuals across organisational boundaries  

Desirable experience/skills required for the role:

• Masters degree, or equivalent lab-based experience.
• Previous experience within the pharmaceutical or peptide industry.
• Experience of working with peptide conjugates or bioconjugation techniques.
