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 Process Engineer you will operate across Technology Readiness Levels 3 to 8; you will lead complex, multi-disciplinary projects that bridge the gap between early formulation development and commercial scale production.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 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.

Our aim is to build an inspiring culture reflected in our working policies, environment, and people.As a Process Engineer you will spend your time working primarily through external manufacturing and production partners, you will be responsible for driving the implementation of new products, particularly injection moulded and coated materials, while coordinating the competing needs of Research, Development and Commercial teams. The role focuses on the delivery of complete products and projects rather than any single processing technology, ensuring robust scale up, improved product performance and long term operational efficiency.In order to succeed in this role you will need a strong technical background in manufacturing, polymer processing, material science or a similar field. Experience delivering multi-disciplinary projects in a TRL-driven environment. Proven track record working with external manufacturing or tolling partners and have a strong analytical and problem solving skills, with the ability to translate technical challenges into actionable
