Chief Science Officer Deep tech startup

9N is developing a new class of modular carbon-conversion systems that turn non-recyclable plastics and other carbon-rich residues into high-value engineered carbon materials. Our mission is to build scalable systems that cut industrial emissions, close material loops and power the next generation of clean, high-performance applications.

We are hiring a Chief Science Officer to lead the scientific core of 9N and shape the full technical journey from concept through to commercial scale.

What You Will Lead

• Set the scientific and technical direction of our carbon-conversion process

• Oversee MVP development, validation, performance testing and cost modelling

• Integrate AI across process control, optimisation and predictive systems

• Coordinate work with external labs, universities and research partners

• Build and manage all technical documentation, white papers and patent strategy

• Turn complex technical data into clear scientific narratives for investors

• Represent 9N in investor meetings and external technical discussions

• Take a hands-on approach to experimentation, iteration and innovation

What You Bring

• PhD in Materials Science, Nanotechnology, Graphene, Chemical Engineering or a related field

• Proven experience developing advanced materials or carbon-based systems

• Ability to convert lab-scale research into manufacturable processes

• Confidence in patent drafting, scientific writing and IP management

• Experience working with external research teams or scientific institutions

• A mindset that enjoys building, testing and pushing new materials in real time

• Genuine enthusiasm for deeptech, climate innovation and creating the future

Why Join 9N

• Become the scientific driver of a technology with global impact

• Work with a sharp, founder-led team focused on high-growth execution

• Full ownership of scientific direction and R&D strategy

• A role designed for builders, not observers

• Competitive salary tied to funding and revenue milestones

• Equity from day one

• Flexible on full time or part time

• Preference for Manchester-based candidates
