Research Scientist – hiPSC & Cardiac Differentiation

Vivo Sphere UK, the UK arm of U.S.

-based biotech company Vivo Sphere, is an innovative life sciences company based at Colworth Science Park, Bedfordshire, dedicated to advancing human-relevant biological models for research and therapeutic discovery. We specialise in developing 3D tissue engineering platforms using human induced pluripotent stem cells (hiPSC) to create next-generation in vitro models.

We are seeking an initiative-taking and skilled Research Scientist to join the Vivo Sphere team on a 10-month contract. The successful candidate will contribute to our research programmes focused on hiPSC culture, cardiac differentiation, and 3D tissue engineering. This is an exciting opportunity for a scientist looking to develop expertise at the forefront of stem cell and 3D tissue engineering technology within a dynamic and collaborative environment.

• Maintain and expand hiPSC lines under feeder-free and defined culture conditions
• Execute and optimise cardiac differentiation protocols to generate cardiomyocytes (hiPSC-CMs) with high efficiency and purity
• Perform quality control assessments including pluripotency characterisation, differentiation efficiency analyses, and functional assays including cell viability assessment and fluorescent imaging
• Troubleshoot and refine cell culture workflows to ensure reproducibility and scalability
• Contribute to the development and optimisation of 3D cardiac tissue constructs using hydrogels, scaffolds, and bioreactor systems
• Assist in the fabrication and validation of micro‑tissue models incorporating hiPSC‑derived cardiac tissue
• Contribute to the development of 3D cardiac tissue constructs, with opportunities to expand into additional tissue types

• Collect, process, and analyse experimental data using appropriate statistical methods
• Perform quantitative image analysis of cell morphology, tissue organisation, and functional assays
• Use software tools (e.g. Graph Pad Prism, R, Python, Image
  
  J/FIJI) for data visualisation and statistical reporting
• Contribute to the preparation of clear, accurate scientific reports and presentations

• Maintain detailed, accurate laboratory notebooks and experimental records in compliance with GLP and internal quality standards
• Ensure safe working practices in line with institutional health and safety policies
• Actively participate in team meetings, scientific discussions, and knowledge‑sharing activities
• Support the ordering and management of laboratory consumables and reagents
• MSc or PhD (completed or in progress) in Cell Biology, Biomedical Science, Biomedical Engineering, or a closely related discipline
• Practical, hands‑on experience working with hiPSC lines, including routine maintenance and passaging
• Demonstrated understanding of stem cell biology principles and differentiation methodologies
• Competence in standard cell culture techniques, such as sterile technique, microscopy, flow cytometry, and/or immunofluorescence
• Experience with data analysis and the ability to apply basic statistical approaches to biological datasets
• Strong attention to detail, scientific rigour, and a commitment to reproducible research
• Excellent organisational skills with the ability to manage multiple tasks and prioritise effectively
• Good written and verbal communication skills in English
• Direct experience with cardiac differentiation protocols and characterisation of hiPSC‑derived cardiomyocytes
• Familiarity with 3D tissue engineering techniques, including hydrogel‑based systems, organoids, or organ‑on‑a‑chip platforms
• Experience with bioreactor culture systems or microfluidic devices
• Proficiency in quantitative data analysis using standard analysis software knowledge of functional assays for cardiomyocyte assessment (e.g. calcium imaging, contractility measurements, MEA).
• Experience preparing scientific reports, posters, or publications
• Prior experience in an industrial or commercial research environment

• A stimulating and supportive research environment at one of the UK's leading science parks
• Hands‑on experience with hiPSC and 3D tissue engineering platforms
• Mentorship from experienced scientists and opportunities for professional development
• Exposure to translational research with real‑world biomedical applications
• Competitive remuneration
• International collaborative work possibilities
• Potential opportunities for future advancement
