As a Principal Process Engineer Specialist, you will provide technical leadership for chemical processes supporting the development, scale-up, introduction and ongoing improvement of intermediates and active ingredients at industrial scale.

You will hold and develop process know-how for assigned chemical steps, ensuring that processes are safe, compliant, robust, sustainable and fit for Supply Chain needs. You will work closely with production, project teams, chemists and global technical networks to solve complex technical challenges, improve performance and support strategic initiatives.

Accountabilities:

• Lead the technical development, scale-up and implementation of new or improved chemical processes for intermediates and active ingredients.
• Define and agree development programmes with relevant stakeholders; plan, oversee and, when needed, carry out laboratory, pilot and full-scale plant trials.
• Provide technical leadership for complex process-engineering projects, including process simulation, design, sizing and equipment specification
• Act as a key technical contact for project teams, providing expertise in process engineering and chemical process development.
