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 £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.
