We’re looking for a technically capable and reliable Senior/Research Scientist to join our Discovery Team at Sortera Bio. This is a lab-based role focused on the operation of our proprietary Deep Screening technology, and provision of broader support for library preparation, NGS, and hit validation workflows.
You’ll become a core operator of Deep Screening, running experiments from inputs to hit profiling on internal discovery and partnership projects. This role would suit a molecular biologist or antibody engineer with the ability to handle complex processes with consistency and who is looking to apply their skills to a cutting-edge technology at a pivotal point in the platform’s development.
-
Run Deep Screening experiments end-to-end on internal and partner projects
-
Prepare and QC library and protein inputs for screening
-
Carry out library preparation and NGS workflows
-
Maintain Deep Screening instruments and reagent stocks
- Accurately record and present experimental data, through contributions to project team discussions and Benchling ELN entries
-
Interpret experimental outcomes using data from Deep Screening and off-platform assays to contribute to hypothesis generation and inform decisions on hit progression
-
Contribute to the development and improvement of protocols and SOPs, documenting optimisations and new methods as the platform evolves
-
Carry out routine molecular biology tasks such as gel extractions, qPCR, Gibson assembly, and related techniques
-
Support display technology selection campaigns as required by project needs
-
Assist with the preparation and QC of enriched library pools as substrates for Deep Screening
-
Isolate and express antibody hits in relevant formats (e.g. scFv, VHH) using established protocols
-
Run off-platform binding assays to generate orthogonal validation data for internal and partner projects
As an early-stage company, we expect roles to evolve as we grow. You'll work in a collaborative, multidisciplinary environment where initiative and attention to detail are valued, and where there are genuine opportunities to expand your technical capabilities.
-
Degree in biochemistry, molecular biology, protein engineering, or a closely related discipline. PhD or equivalent industry experience preferred
-
Experience with antibody/protein or peptide discovery and engineering
-
Molecular biology skills such as qPCR, Gibson assembly, site-directed mutagenesis, and related techniques
-
Ability to execute complex laboratory protocols with precision and consistency
-
Strong attention to detail and commitment to rigorous documentation and data integrity
-
Good organisational skills and able to manage multiple tasks in a startup environment
-
Team player with clear communication skills and a proactive approach to science
-
Practical experience with a display technology such as phage, yeast, or ribosome display
-
Experience with a biophysical characterisation method (e.g. SPR, BLI, MST, or ITC)
-
Familiarity with NGS library preparation and sequencing data interpretation
-
Proficiency in Python or equivalent for data analysis
-
Experience with VHH and scFv antibody formats
-
Experience with functional assay development (cell-based, biochemical, or immunoassay formats)
-
Understanding of antibody sequence-function relationships and early-stage hit triage
