Job description

You’ll play a key role in shaping the future of cultivated fat production by leading the design, optimisation, and scale-up of bioprocesses from bench through to industrial scale.

Working closely with engineers, biologists and software experts, you’ll drive process development and integration of novel bioreactor designs, ensuring our technology is ready for our next-generation manufacturing facility. This role offers both technical depth and leadership responsibility – guiding experimental strategy, mentoring colleagues and setting direction for scale-up operations.

What you’ll do

• Lead the development and optimisation of scalable bioprocesses for cultivated fat production
• Design, implement, and validate processes for novel bioreactor formats and monitoring systems
• Scale operations from bench and pilot scale through to industrial (>1000L) production
• Hands‑on contribution for innovation and troubleshooting of upstream and downstream processes
• Optimise downstream operations to maximise harvest efficiency and throughput
• Oversee sterile operations, process control and analytical instrumentation strategies
• Write, review and maintain SOPs and technical documentation to enable robust operations
• Mentor engineers and technicians, sharing expertise in process design and scale-up
• Collaborate across software and hardware teams to integrate innovative instrumentation and automation technologies

What we’re looking for

• Master’s degree (or equivalent experience) in biochemical engineering, cell biology, biomanufacturing, or related discipline
• At least 6 years experience in bioprocess development and scale-up in an industrial setting
• Hands‑on expertise with mammalian cell culture in suspension bioreactors
• Proven experience scaling processes to pilot and industrial scales (1000L+)
• Track record of developing and transferring processes into novel bioreactor designs
• Strong background in sterile operations, process monitoring, and analytical instrumentation
• Ability to lead projects, coordinate cross‑functional teams, and mentor colleagues
• Enthusiasm, curiosity, and a drive to engineer biology at scale
• Ideally you’ll also have experience with
• Multiple bench- and pilot‑scale bioreactor systems
• Large‑scale sterile media preparation and utilities for GMP environments
• Tech transfer and validation of processes into manufacturing facilities
• R&D project leadership and cross‑team collaboration
• ELNs, LIMS and data‑driven process optimisation

Why join us?

• Combine deep technical work with team leadership to meet ambitious scale up goals in a brand new industry
• Work alongside expert hardware and software teams to implement a novel bioreactor platform for food and biotech
• Join a fast‑paced startup culture that values responsibility, agency and technical excellence
