Job Purpose
To be an integral member of ARC’s laboratory team, supporting the design, development and delivery of internal and client-facing in vitro diagnostic (IVD) and companion diagnostic (CDx) programmes.

Reporting to the Laboratory Manager, the Associate IVD Scientist will support assay development, optimisation, verification and validation, alongside clinical trial sample testing and laboratory operations. Working closely with experienced scientists and colleagues across ARC, the postholder will contribute to accurate, reliable scientific outputs while developing their technical expertise within a quality-driven laboratory environment.

Key responsibilities

• Support the optimisation, verification and validation of molecular diagnostic assays, including NGS, PCR and related technologies.
• Perform biomarker testing and sample analysis, ensuring accuracy, quality and adherence to approved protocols.
• Analyse experimental results and contribute to scientific reports, presentations and project documentation.
• Maintain accurate, complete and traceable laboratory records in accordance with quality systems and approved procedures.
• Carry out laboratory activities in line with applicable regulatory requirements, quality standards and health and safety procedures.
• Collaborate with Laboratory, Quality, Regulatory and Research Operations teams to support project delivery and client outcomes.
• Participate in structured training to develop expertise in assay validation, diagnostic development and laboratory operations.
• Keep informed of developments in molecular diagnostics, precision medicine and scientific best practice.
• Identify opportunities to improve laboratory processes, efficiency and quality.

What you’ll bring
We are looking for a scientifically minded individual with at least two years’ experience working within a laboratory environment, strong attention to detail and an interest in molecular diagnostics and precision medicine. Experience in next-generation sequencing (NGS) would be particularly advantageous.

Essential experience

• A BSc in Biological Sciences or another relevant scientific discipline.
• A minimum of two years’ experience working within a laboratory environment.
• Practical experience using molecular biology techniques, such as PCR.
• Practical experience in next-generation sequencing (NGS).
• A basic understanding of assay verification and validation principles.
• Awareness of quality and regulatory requirements within laboratory environments.
• The ability to record, analyse and report scientific data accurately.
• Strong organisational skills, with the ability to prioritise tasks and meet agreed deadlines.
• Effective communication skills and the ability to work collaboratively across different functions.
• A commitment to learning, continuous improvement and developing technical expertise.

It would be an advantage if you also have

• A postgraduate qualification, such as an MSc or PhD, in a Life Science or related field.
• Experience with immunohistochemistry (IHC), histology or biomarker testing.
• An understanding of IVDR, ISO 15189, CAP or related regulatory and quality frameworks.
• Exposure to precision medicine, molecular diagnostics or companion diagnostics.

Why this role matters
At ARC, laboratory services sit alongside deep clinical, regulatory and technology expertise. Your work will support the development and testing of diagnostics used in precision medicine clinical trials, helping our teams and customers deliver high-quality research and accelerate patient access to appropriate treatments.

We are an equal opportunity employer; applications are welcome from all and appointment will be made on the basis of merit.
