• Do you want to apply physics and advanced modelling to solve real manufacturing challenges with a direct impact on business performance?
• Are you excited by the opportunity to design next‑generation processes and equipment that support the journey to net‑zero carbon manufacturing?
• Would you thrive in a role where simulation, experimentation, pilot testing and industrial‑scale implementation all come together?
• Do you enjoy working with experts across engineering, data science, industry and academia to tackle complex, cutting‑edge problems?

As R&D Engineer
, you would have the opportunity to work on high‑profile projects that are at the heart of the production process and to have a direct impact on the profitability of the business. You will work on the design of next‑generation key equipment and processes to meet the company’s net‑zero carbon targets. You will also have the opportunity to work with the latest analytical equipment, simulation software, data science applications and link with external experts from industry and academia to solve cutting‑edge problems.

• Develop physics‑based and mathematical models for key manufacturing processes in glass fibre production, including thermal losses, fluid flow and combustion dynamics.
• Build a strong understanding of the physics across the full manufacturing process, including melting, fibreising and curing, to support the CO₂‑free manufacturing journey.
• Translate modelling insights into proof‑of‑concept designs and industrial‑scale testing on pilot lines and production sites, leading these activities where required.
• Work with CFD engineers, physicists and other specialists to ensure simulations apply the appropriate physics for each application and scale.
• Collaborate with process engineering teams to identify critical parameters, optimise operations and assess the impact of process changes on forces, flows, stresses and overall behaviour.
• Partner with product development teams to improve understanding of the factors affecting product quality and performance, and recommend enhancement strategies using validated models.
• Act as a consultant to Core R&D teams requiring deeper physics insight.
• Work with internal and external experts, including glass scientists, combustion specialists, CFD modellers and process experts, to deepen understanding of fibreising and related phenomena.
• Develop knowledge of manufacturing processes across Knauf Insulation and produce clear reports to support effective knowledge sharing across process and engineering teams.

This role requires travel to collaborate with plant teams and external stakeholders. Expected business travels is up to 30% of time.

We are interested in you as a person; your attitude, behaviours and values. As long as you have the willingness to learn anything you need for the role that you don't already have, we’d love to speak to you.

• Degree in Physics or Physical Science with advanced applied Mathematical content (i.e. Physics, Mathematics, Mechanical Engineering, Aerospace Engineering).
