The Role
At Notpla, we’re at the forefront of sustainable innovation, creating natural alternatives to single-use plastic packaging that are carefully engineered to help build a healthier planet. Founded on the belief that nature knows best, we’re an innovative, action-oriented scale-up developing and manufacturing uncompromisingly natural packaging solutions from seaweed and plants.
As a Senior Material Scientist, you’ll spearhead scientific and technological breakthroughs, playing a pivotal role in developing natural polymer technologies to replace plastic. This role will suit someone with a background in Materials Science, Polymer Chemistry, or Chemical Engineering, with hands-on experience working with natural materials such as biopolyesters, rubbers, resins, seaweed, and/or processes such as PET recycling or polymer extrusion.
This is an exciting time to join Notpla — we’re on the brink of a record-breaking year for revenue and on track for major growth in the next 18–24 months. To support this, we have just secured a £20 million Series A+ fundraise, enabling us to scale our growth and environmental impact faster than ever.
Beyond offering meaningful roles and a vibrant working environment, Notpla provides competitive compensation, including EMI Share Options, a zero-carbon pension scheme, discounts with local businesses, and subsidised social activities. Our office-first hybrid working policy lets you work in the way that maximises your productivity while maintaining a dynamic and collaborative atmosphere. We’re a social business with regular clubs and events, and we’re proud of how our diverse, mission-driven community works together to make plastic disappear.
Led by strong values, all Notpla employees are encouraged to take ownership of their domain, enjoying a high degree of autonomy. Our aim is to build an inspiring culture reflected in our working policies, environment, and people.
As a Senior Material Scientist, you’ll balance fast-paced feasibility initiatives with in-depth polymer and process development. Your work will be highly hands-on and collaborative, engaging with cross-disciplinary teams and international partners. You’ll tackle complex materials challenges, coordinate trials, scout novel natural polymer opportunities, and engage with a network of scientific experts and labs to bring innovation to life.
Within the Innovation Team, you’ll thrive in a setting that embraces ambiguity and agile ways of working. You’ll collaborate closely with colleagues from diverse backgrounds — such as design, engineering, and business — to develop new materials and products. A true innovator, you’ll explore the unknown, constantly learning and pushing the boundaries of science rooted in nature.
Key Responsibilities
* Play a central scientific role in Notpla’s in a large funded consortium project, executing and coordinating polymer chemistry activities across the consortium.
* Pioneer new approaches to polymer synthesis from abundant natural materials.
* Conduct feasibility studies and fast-paced discovery projects to address material science and packaging challenges.
* Collaborate closely with cross-disciplinary teams — including designers, engineers, seaweed specialists, and business development managers — to solve complex problems.
* Identify, source, and test natural materials; develop formulations that meet performance, sustainability, and cost targets.
* Design and execute experiments, analyse data, and present findings to drive decision-making and project progress.
* Stay up to date with the latest scientific and industry advancements, integrating new knowledge into projects.
* Contribute to the development of intellectual property, including patents and trade secrets.
* Provide technical input for grant and client proposals to secure funding.
* Lead in-depth development projects to advance the understanding of seaweed and biomaterials for packaging applications.
* Characterise polymer structures, reactions, and material behaviour, and conduct performance, shelf-life, and compatibility studies.
* Represent Notpla to external partners, academic institutions, and commercial labs; coordinate third-party testing as needed.
* Develop technical strategies and approaches to solve key challenges.
* Mentor colleagues (scientists, designers, engineers) to help develop their technical skills and support their project work.
* Plan and manage your own workload effectively.
