Recruitment at Domainex – drug discovery CRO in Cambridge

Established since 2001, Domainex is a privately-owned, rapidly growing drug discovery therapeutics company with expertise spanning disease target expression, hit discovery, hit-to-lead identification and lead optimisation. We have established a reputation for a high-quality and innovative approach, and have a sustained track record of delivering preclinical drug candidates. Our clients include leading academic groups, biotechnology and pharmaceutical companies from the UK and overseas.

At an exciting stage in its evolution, Domainex has recently moved in to a newly refurbished facility on Chesterford Research Park, near Cambridge, giving an over two-fold increase in laboratory space. The company is now looking to welcome experienced and ambitious scientists to our team.

The Domainex team has been recruited from major companies and leading universities, and we are highly experienced in every aspect of drug discovery. Our state of the art laboratories are located near Cambridge, at the centre of Europe’s largest biotechnology cluster. We have a multi-disciplinary, collegiate culture where ideas, innovation, commitment and collaboration are encouraged.

Assay Biologists - Cambridge, UK

BioassayBuilder is a suite of services covering protein expression, assay development, high throughput screening, compound profiling (potency, selectivity, phenotype, and mechanism of action) and off-target safety assessment to support the generation of pre-clinical candidates. Our team of experienced molecular, assay and cell biologists are able to support our clients in ways that are precisely adapted to their needs.

This role requires the ability to plan and implement experimental programmes, to solve any problems that arise, and to work effectively within project teams to deliver high quality data. Other required attributes will include diligent reporting of results, data interpretation and an ability to make recommendations for further studies. Laboratory work is the major component of these varied and challenging roles, and most of our bioassays are run on automated instrumentation in medium-throughput mode. It will also be essential to able to communicate results effectively and provide data interpretation to our customers.

Candidate requirements

Qualified to BSc or PhD level, all applicants must have some prior industrial experience of running biochemical and/or cellular assays in at least one of the following categories; enzyme kinetics (including kinases), protein-protein interactions, cellular efficacy and/or mechanism of action studies, or phenotypic screening. Experience of working with laboratory automation is preferential. It would be desirable, but not essential, to have experience in some of these techniques: biophysical techniques; inflammation or oncology cellular and disease models; use of FACS equipment; primary cell culture; identification of pharmacodynamic markers in cellular assays.

Candidates must have experience of working with microtitre plate-based assays in a drug discovery setting, will have developed assays for compound screening and potency determination in a variety of formats, and will be proficient in data processing and analysis.
