In short

• Join us at the heart of the revolution. As a hands-on Lead Process Engineer at our LightSpray production sites, you will be the critical link between engineering and live operations. You will support a growing production system, ensuring this disruptive technology is robust, repeatable, and ready to scale.As the Lead Process Engineer, you will own the day-to-day process stability, execute experimental designs (DoE), and drive root cause analysis on faulty products. Working closely with the Senior Lead Process Engineer, you will support process validation, contribute to novel process development, and lead field deployment of LightSpray machinery across global sites
• Drive Data-Driven Process Validation: Execute experimental designs (DoE) and process validation protocols to ensure repeatability and robustness for high-volume manufacturing
• Hands-On Machine & Product Troubleshooting: Serve as the primary technical point of contact for machine parameters and material processing issues. Perform root cause analysis to resolve critical process deviations and product defects
• Support Deployment & Global Readiness (Up to 20% Travel): Visit global production sites to support machine readiness, assist with equipment deployment, and translate factory floor feedback into technical improvements
• Bridge Innovation to Production: Execute process-related tasks on multidisciplinary projects, bridging material and process innovations from the lab to production lines
• Documentation & SOPs: Develop and maintain Standard Operating Procedures (SOPs) based on real-time operational feedback to ensure process repeatability across sites

Your story

• Degree in Engineering, Material Science background or an apprenticeship in polymer processing or automation
• 6+ years of Industry Experience: Solid track record in process execution, machine troubleshooting, and process validation within polymer processing or related manufacturing technologies
• Practical experience executing experiments, handling machine parameters, and performing on-site troubleshooting
• Knowledge of pneumatic systems, the ability to understand wiring schematics, and experience wiring electrical components is a big plus
• Demonstrated ability to perform root cause analysis and work systematically using data-driven approaches
• Willingness to travel globally up to 20% for equipment deployment and site support, with strong cross-functional communication skills
• Fluent in English (written and spoken)

As a member of the Innovation Technology Engineering team, you will join a multidisciplinary collective of experts redefining the future of sports goods manufacturing. We bridge the gap between digital theory and physical industrialization by building bespoke machinery, processing novel materials, and leveraging advanced modeling and simulation. Our mission is to unlock the potential of next-generation manufacturing through LightSpray technology
