Type: Full Time
Start: Immediate
Minimum Experience: +5 years industrial experience

Be part of shaping Stem’s future to deliver the next generation of transformational food ingredients. Our mission is to tackle the world’s greatest public health crisis; excessive sugar consumption. We use cutting edge biological science to create functional, nutritional, and economic replacements for conventional sugar, that work across the food industry.

Stem operates from the lab bench to manufacturing plant and development kitchen to end consumers. We value our networks and have strong connections to the University of Cambridge’s Biochemistry Department. It is imperative we carefully select outstanding individuals who care about our mission and are passionate about challenging the status quo.

As a team, we are committed to working together to create a great work environment where smart and engaged people tackle meaningful challenges and make an impact. If this excites you, we encourage you to join us as Bioprocessing Team Leader

• 5+ years industry experience in a relevant technical role

Required Skills:
• Good understanding of microbial bioreactor culture including considerations at scale, microbial growth and physiology, media optimisation and product recovery
• Demonstrated practical ability to grow bacteria, yeast and filamentous fungi. Experience of working with filamentous fungi is particularly favoured
• Proficiency with techniques such as design of experiments and statistical approaches to maximise information generated from the minimum number of experiments
• Skill with standard methodologies for protein recovery as well as understanding of how upstream decisions affect downstream processing
• Expertise in use of bioreactors at various scales from lab bench to manufacturing plant
• Ability to plan, execute, interpret results and report / present own work and that of team
