Bioprocess Engineer

Cellcraft® is a B2B cultivated meat company based in Cambridge tackling global food security and sustainability challenges. Our AI-driven bioelectronic technology powers the Cellcraft® Farm: an end-to-end, scalable Cultivated Meat (CM) Manufacturing Platform to empower food producers to make their own delectable, sustainable cultivated meats locally. Cellcraft is the world’s first cultivated meat company with a focus on software and analytics. We believe the future of meat must be both sustainable and irresistible.

As a Bioprocess Engineer, you will play a key role in developing, optimising, and scaling bioreactor-based processes for cultivated meat production. You will be adaptable and able to handle a range of cross-functional projects in other functional areas including cell line and media development, assay development, and downstream processing, to ensure robust, efficient, and scalable production systems.

Cellcraft is a fast-paced environment. You must be a problem solver capable of applying initiative who enjoys seeing their ideas come to fruition.

• Design and execute bioprocess experiments for the development and optimisation of single cell and aggregate cell cultivation in stirred tank and 3D bioreactors.
• Develop and implement process control strategies (pH, dissolved oxygen, feed strategies, agitation, etc.) to maintain robust cell growth and differentiation.
• Lead maintenance and suspension adaptation of cell lines to enable scalable bioprocessing.
• Support translation of laboratory-scale processes into scalable, manufacturable systems.
• Support process transfer, scale-up, and tech transfer to manufacturing partners.
• Analyse process data, generate technical reports, and present findings to internal stakeholders.
• Contribute to, and evaluate bioreactor system design, including hardware, sensors, and automation integration.
• Ensure processes comply with food safety and regulatory requirements.

Required experience:

• Bachelor’s or Master’s degree in Biology, Bioprocess Engineering, Biotechnology, or a related field.
• A PhD or equivalent industrial experience in cell culture, bioprocessing, fermentation, or related biomanufacturing environments.
• 3+ years’ hands-on experience in setting up and operating stirred tank bioreactors in cell therapy, biologics, or food biotech.

• Strong knowledge of mammalian cell biology, growth kinetics, bioreactor design, and process scale-up.
• Hands-on experience with bench-scale bioreactors
• Strong knowledge of measurement, optimisation, and scaling of bioreactor parameters including mass transfer (kLa), pH, temperature, agitation (tip speed, power input), shear force, metabolomics etc.
• Experience with process analytical technologies (PAT), automation, and process modelling
• Strong analytical, problem-solving, and data interpretation skills.
• Passion for sustainable food and advancing cultivated meat technologies.

Desirable experience:

• Design and operation of continuous perfusion within bioreactor systems
• Culture of induced pluripotent stem cells and other immortalised cell lines
• Knowledge of myogenic and adipogenic differentiation
• Tissue engineering including 3D organotypic culture.
• Experience with media and cell line development
• Understanding of computational modelling of fluid dynamics, cell growth and other phenomena within bioreactors
• Sourcing and procurement of materials and equipment for bioreactors

• Competitive compensation and stock options
• Private health Insurance
• Potential for excellent career progression
• Exposure to an up-and-coming disruptive and innovative market
• Opportunity to be at the forefront of the cultivated meat industry and make a tangible impact on global sustainability.
