Job Summary

The Molecular Assay Development Scientist will support the development, optimisation and validation of molecular assays within Cyted’s new molecular R&D laboratory, with a key focus on next generation sequencing. Working under the guidance of the Molecular Assay Development Manager, this role will contribute to discovery research, experimental planning, wet‑lab execution, data analysis and documentation required to advance new biomarker assays toward diagnostic adoption. As a new laboratory, the role will be key to laboratory set‑up including equipment and assay validations, protocol development, and in shaping core working practices. This role will also be key in designing and carrying out laboratory experiments, evaluating new molecular technologies and methodologies, maintaining high‑quality molecular laboratory practices, and collaborating closely with R&D dry lab, project management, QA and clinical teams to progress assays through development stages.

Working Pattern and Location

Full‑time, 37.5 hour week. The role holder may be required to work flexibly. The Molecular Assay Development Scientist will be based within Cyted's molecular lab at Ground Floor Building 3 Old Swiss, 149 Cherry Hinton Road, Cambridge, United Kingdom, CB1 7BX.

What You Will Be Doing

• Perform wet‑lab molecular experiments to support discovery, development and validation of new biomarker assays.
• Assist in evaluating and implementing new molecular technologies in collaboration with the Molecular Assay Development Manager.
• Work closely with the dry lab team to plan experiments, generate data and interpret results.
• Prepare and maintain laboratory documentation including experimental records, validation plans, reports, SOPs and training materials.
• Support the optimisation of assay workflows for accuracy, reproducibility and cost‑effectiveness.
• Contribute to the translation of assays from R&D into diagnostic workflows, working with project management, QA and clinical operations.
• Maintain high laboratory quality standards, including adherence to molecular QA practices and preparation for audit and accreditation activities.
• Perform equipment maintenance, troubleshooting and reagent management in the molecular laboratory.
• Perform laboratory maintenance to ensure clean, safe, compliant and efficient laboratory operations at all times.

How We Work

At Cyted, how we work is just as important as the impact we create. Our values shape how we collaborate, operate and support the clinicians and patients who ultimately rely on our diagnostics. As a Molecular Assay Development Scientist, you’ll bring those values to life through rigorous science, disciplined execution and a deep commitment to quality in everything you do in the laboratory. Care deeply about delivering accurate, clinically meaningful diagnostics, and for you, care means precision, reproducibility and scientific integrity. You’ll approach molecular assay development with attention to detail and a strong quality mindset, ensuring experiments are well designed, data is robust and documentation is thorough. From nucleic acid extraction through NGS library preparation and assay optimisation, your work will directly contribute to building assays that can be trusted in clinical settings. We own your science with confidence and accountability. You’ll take responsibility for executing wet‑lab experiments, supporting assay development, optimisation and validation, and contributing high‑quality data to multidisciplinary teams. Working under the guidance of the Molecular Assay Development Manager, you’ll plan experiments thoughtfully, interpret results critically and maintain clear, compliant records that support regulatory and diagnostic progression. We aim high. Cyted is growing, and with that comes the challenge of building new molecular capabilities from the ground up. As part of a new molecular R&D laboratory, you’ll help establish robust laboratory practices, support equipment and assay validation, and contribute to shaping core ways of working. You’ll support the transition of assays from discovery through development toward diagnostic adoption, balancing scientific ambition with practicality and robustness. You’ll be expected to dive deep. You’ll build a strong understanding of Cyted’s biomarker strategies, molecular technologies and assay workflows, working closely with dry lab, project management, QA and clinical teams. Whether evaluating new technologies, troubleshooting assay performance or supporting workflow optimisation, you’ll bring curiosity, structure and problem‑solving skills to complex scientific challenges. We encourage everyone to challenge and commit. You’ll actively contribute to scientific discussions, share learnings, and help improve protocols, documentation and laboratory processes. You’ll question assumptions, suggest improvements and support continuous improvement in assay performance, efficiency and quality, while committing fully to agreed approaches and project goals. And above all, we deliver. This role requires momentum, reliability and results. You’ll progress experiments efficiently, generate high‑quality data and support assay development milestones. Every experiment you run, every protocol you refine and every dataset you analyse strengthens Cyted’s ability to deliver innovative molecular diagnostics at scale.

Person Specification

• BSc or MSc in Molecular Biology, Genetics, Biomedical Science or a related field.
• Hands‑on experience in molecular biology techniques, such as NGS library preparations and sequencing, PCR/qPCR, nucleic acid extraction and assay optimisation.
• Experience working in a molecular laboratory or diagnostic/R&D environment.
• Familiarity with documentation processes including SOPs, validation reports and experiment records and understanding of clinical sample handling and molecular QA standards.
• Experience working to ISO15189 or other regulatory standards.
• Strong wet‑bench molecular skills with the ability to execute precise, high‑quality experiments.
• Excellent attention to detail, ensuring accurate data generation and documentation, and strong analytical ability to interpret experimental outcomes and troubleshoot.
• Organised, proactive and able to manage workload across multiple projects.
