Senior Product Design Engineer

Purpose of Role:

You will collaborate closely with our production and technical service teams to deliver cutting-edge fenestration products that push the boundaries of design, performance, and functionality, while being mindful of real-world production constraints.

Main Duties and Responsibilities:

• Driving Innovation: Lead the development of ground breaking, high-quality fenestration products. Bring fresh, creative ideas to life by exploring new design possibilities, materials, and manufacturing techniques. Inspire the team to think outside the box while balancing innovation with Design for Manufacture.
• Design for Manufacture: While pushing boundaries with innovative designs, ensure that the concepts are optimized for efficient production, assembly, and cost-effectiveness. Design with a deep understanding of extrusion processes (particularly PVCu) and tooling requirements to make sure innovative designs can be practically brought to life.
• Collaboration with Production & Technical Service Teams: Work together with the production team to ensure the feasibility of innovative designs from a manufacturing standpoint. Collaborate with the technical service team to identify real-world challenges during installation or field use and iterate designs to solve these problems while maintaining innovation.
• Extrusion Process & Tooling: Use your knowledge of extrusion processes and tooling to design products that can be innovatively produced at scale. Collaborate with the production team to ensure that tooling and material flow support your innovative design ideas without compromising manufacturability.
• Hands-On Prototyping: Lead the prototyping process by creating functional models and mock-ups to test innovative design concepts. Use 3D printers, manual tools, and other fabrication methods to bring your creative ideas into tangible forms and validate their performance and manufacturability.
• CAD Design: Utilize SolidWorks and AutoCAD to create detailed, innovative designs that push design boundaries, while ensuring they can be efficiently manufactured. Develop complex 3D models, technical drawings, and assembly instructions that clearly communicate complex ideas to the wider team.
• Material Selection & Optimization: Choose new, innovative materials and optimize them for production processes such as extrusion, ensuring that the materials align with both the performance goals of the product and the constraints of the manufacturing process.

Key Skills & Knowledge:

• Experience with sustainable design practices and innovation in eco-friendly materials and manufacturing processes.
• Ability to mentor junior team members, encouraging innovative thinking and creativity while ensuring design feasibility.
• Strong problem-solving skills and excellent communication skills, with the ability to work effectively with cross-functional teams, including production, technical service, suppliers, customers and engineering, to turn innovative designs into practical products.
• Advanced use of Microsoft Word, Excel & Outlook (Ability to create working complex spreadsheets)
• Installation and fabrication knowledge of building and fenestration products

Qualifications & Experience:

• Bachelor’s degree in industrial design, product design, mechanical engineering, or a related field (or equivalent experience).
• 10+ years of experience in product design, with a strong focus on innovative design, project management, design for manufacture, and extrusion processes.
• Experience with product testing, field installations, and real-world performance evaluations, with a focus on applying feedback to iterate and innovate.
• Hands-on prototyping experience using 3D printers, manual tools, and other fabrication techniques, with a proven ability to turn innovative ideas into functional prototypes.
• 10+ years’ experience working in the PVCu / Aluminium extrusion industry
