Job Description:

Role: Senior Scientist – Process Development

Company: ATMP focussed biotech

Location: London, on-site

Full time / Permanent

We are currently supporting an innovative clinical-stage biotechnology company developing next-generation engineered immune-cell therapies targeting severe diseases.

This is an exciting opportunity for an experienced and highly motivated scientist to join a multidisciplinary Process Development team focused on development of advanced cell therapy manufacturing platforms for clinical application.

The successful candidate will play a key role in driving process development activities for engineered-cell therapy programmes progressing through clinical development, alongside supporting platform expansion into additional therapeutic indications.

The role will be highly laboratory-based and collaborative, involving close interaction with discovery, translational, manufacturing, quality and clinical teams, as well as external partners and CDMOs.

Key responsibilities include:

  • Driving development and optimisation of cell therapy manufacturing platforms for clinical application
  • Designing and executing process development experiments and analysing complex datasets
  • Supporting development and optimisation of engineered-cell workflows involving mRNA/nucleic acid delivery technologies
  • Contributing technical expertise around transfection, non-viral engineering and engineered immune-cell process optimisation
  • Supporting process robustness, manufacturability and scalability activities
  • Technology transfer of manufacturing processes into GMP manufacturing environments
  • Supporting regulatory and quality documentation activities
  • Cross-functional collaboration with internal scientific teams and external partners
  • Supporting development of manufacturing workflows for late-stage clinical programmes
  • Contributing to continual improvement of process understanding, data collection and process performance
  • Supporting and mentoring junior scientists where appropriate

We are particularly interested in candidates with hands-on experience across areas such as:

  • mRNA / RNA delivery
  • Transfection / electroporation / nucleofection
  • Non-viral engineering approaches
  • Engineered immune cells (CAR-T, CAR-NK, macrophages etc.)
  • LNP or nucleic acid delivery systems
  • Translational cell therapy or CGT process development
  • Technology transfer and interaction with external manufacturing partners/CDMOs

Requirements:

  • BSc, MSc or PhD in Cell Therapy, Immunology, Molecular Biology, Biotechnology or related field
  • Industrial experience within process development, cell therapy, gene therapy or advanced therapeutics
  • Strong laboratory and experimental design capabilities
  • Experience working within multidisciplinary project teams
  • Understanding of translational development and manufacturing considerations within advanced therapies
  • Excellent communication and presentation skills

Previous experience across GMP manufacturing, regulatory submissions, process validation or late-stage clinical development would be advantageous.
