Senior Scientist Protein and Cell Sciences
Job Summary
Job Title: Senior Scientist; Protein and Cell Sciences
Location: Cambridge UK
Salary: Competitive with excellent benefits!
Introduction to role:
Are you ready to turn recombinant protein design into therapies that change the way cancer is treated In this laboratory-based role you will deliver high-quality antigens that fuel our biologics discovery portfolio and help move promising ideas into the clinic. Your work will directly enable teams to evaluate novel modalities and make faster better-informed decisions for patients.
As a Senior Scientist in Protein and Cell Sciences you will design express purify and characterize recombinant proteins that underpin antibody discovery and other biologics programs. You will use modern computational tools alongside rigorous experimental methods to ensure the proteins you produce behave as intended. Can you see your experiments influencing cross-functional strategy in real time This is the bench where that happens.
Accountabilities:
Recombinant Antigen Design: Apply computational structural biology (including AlphaFold andProteinMPNN) to design target proteins that are fit-for-purpose for discovery and development.
Expression Vector Engineering: Design recombinant expression vectors using standard molecular biology techniques;optimizeconstructs for expression and stability.
Protein Production: Express and purify recombinant proteins using bacterial and transient mammalian systems ( HEK CHO) building robust scalable methods and standard operating procedures that improve throughput and reproducibility.
Functional Characterization: Develop and deploy assays tomonitorprotein expressionfunctionand quality (e.g. SDS-PAGE analytical SEC ELISAcell basedassays OCTET) ensuring integrity and suitability for downstream applications.
DataDocumentationand Insight: Make detailed observationsanalyzedataand interpret results;maintainrigorous electronic laboratory notebooks and databases to create a reliable evidence base for decision-making.
Collaboration and Communication: Report and present findings to project teams and the department; contribute scientific judgment that shapes early- and late-stage therapeutic programs.
Continuous Improvement: Troubleshoot experimental processes and apply automation in molecular biology and protein expression to reduce cycle times and increase consistency.
Essential Skills/Experience:
BSc or higher degree with lab-based experience
Practical knowledge and demonstrable technical skills in molecular biology cell culture transient proteinexpressionand protein purification
Computational structural biology knowledge enabling recombinant protein (antigen) design use of AlphaFoldProteinMPNNand related computational methods
Practical knowledge of developing and deploying assays tomonitor/assess protein expressionfunctionand quality(e.g. SDS-PAGE analytical SEC ELISAcell basedassays OCTET).
Excellent communication capable of developing good working relationships with individuals in team; experience working within a team environment
Ability tomaintainaccurateexperimental recordsdatabasesand use/develop standard operating protocols
Demonstrable ability to troubleshoot experimental processes relating to protein expression and purification
Application of automation to laboratory processes in areas of molecular biology and protein expression
Desirable Skills/Experience:
Experience designing recombinant expression vectors and producing proteins in bacterial and transient mammalian systems ( HEK CHO)
Experience building robust methods and standard operating procedures for protein production
Experience developing assays for recombinant protein functionality and integrity
Experience with electronic laboratory notebooks and data systems
Experience reporting and presenting results to project teams
Experience collaborating with cross-functional colleagues and external outsourcing partners
