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.<h3>Key Responsibilities</h3><ul><li>Play a central scientific role in Notpla’s in a large funded consortium project, executing and coordinating polymer chemistry activities across the consortium.</li><li>Pioneer new approaches to polymer synthesis from abundant natural materials.</li><li>Conduct feasibility studies and fast-paced discovery projects to address material science and packaging challenges.</li><li>Collaborate closely with cross-disciplinary teams — including designers, engineers, seaweed specialists, and business development managers — to solve complex problems.</li><li>Identify, source, and test natural materials; develop formulations that meet performance, sustainability, and cost targets.</li><li>Design and execute experiments, analyse data, and present findings to drive decision-making and project progress.</li><li>Stay up to date with the latest scientific and industry advancements, integrating new knowledge into projects.</li><li>Contribute to the development of intellectual property, including patents and trade secrets.</li><li>Provide technical input for grant and client proposals to secure funding.</li><li>Lead in-depth development projects to advance the understanding of seaweed and biomaterials for packaging applications.</li><li>Characterise polymer structures, reactions, and material behaviour, and conduct performance, shelf-life, and compatibility studies.</li><li>Represent Notpla to external partners, academic institutions, and commercial labs; coordinate third-party testing as needed.</li><li>Develop technical strategies and approaches to solve key challenges.</li><li>Mentor colleagues (scientists, designers, engineers) to help develop their technical skills and support their project work.</li><li>Plan and manage your own workload effectively. </li></ul> Salary £38,000 - £45,000 + EMI Share Options

We are a combination of designers and chemists, engineers and entrepreneurs. We’re hard to define because what we’re doing hasn’t been done before. We create advanced packaging solutions that disappear, naturally.
