Phage Display - Scientist/Senior Scientist
About Us
Gastrobody Therapeutics is an early stage, University of Cambridge spin-out company developing ultrastable, orally-administered protein therapeutics to treat gastrointestinal tract diseases, including inflammatory bowel diseases (IBD). Our platform combines computational protein design, protein engineering, and experimental validation to create highly stable, functional therapeutic binders suitable for oral delivery. We are building a multidisciplinary team at the intersection of computational biology, protein engineering, and translational therapeutics.
The Role
We are seeking to expand our team with an experienced phage/yeast display scientist to join the platform technology team. The successful candidate will apply display technologies to generate, identify, and optimise protein binders against therapeutic targets to support and accelerate our drug discovery programmes.
This role is ideally suited to a scientist with strong expertise in phage/yeast display and protein engineering who is excited to work in a highly collaborative and fast-paced start-up environment. The candidate will contribute across multiple discovery-stage projects, helping to advance the development of next-generation orally administered biologics.
The candidate will work in a dynamic, project-focused environment, aiming to accelerate the development of life-changing medicines.

Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
The role will include the following responsibilities:
- Employing display technologies to select and optimise protein binders against therapeutic targets, including library design.
- Designing and executing display selection campaigns using phage, yeast, or mammalian display platforms.
- Screening and validating hits using high-throughput assays including ELISA, Spy-BLI, and cell-based assays.
- Analysing and interpreting experimental data to support iterative optimisation of binder affinity, specificity, and developability.
- Subcloning plasmid constructs for protein expression and engineering.
- Performing protein expression, purification, and biophysical characterisation of engineered binders (BLI, SPR, DSF or DSC).
- Supporting library generation and affinity maturation workflows.
- Collaborating closely with multidisciplinary scientists across discovery, protein engineering, and computational biology teams.
Requirements
- PhD in a relevant area of biology, biochemistry, molecular biology, protein engineering, or related discipline.
- At least 3 years of hands-on experience carrying out display campaigns.
- Theoretical and practical expertise in phage, yeast, and/or mammalian display technologies and selection methodologies.
- Experience working with antibody or protein display libraries.
- Strong and evidenced molecular biology & cloning proficiency.
- Experience in protein expression, purification, and biochemical and biophysical characterisation.
- Ability to work independently in a fast-moving startup environment.
- Strong interpersonal skills and interact effectively with scientists across disciplines to generate timely and informative data.
