What you'll need:

You will bring around eight years or more of supplier quality, manufacturing or manufacturing engineering experience in a production environment, along with a degree in engineering or another technical discipline. You will have extensive experience of supplier failure analysis, root cause analysis and corrective action, and of putting robust process controls in place across a supply chain. You weigh several sources of data and alternative solutions before committing to a path.

You will know Quality Management Systems such as AS9100 and the ISO quality management standard, quality tools such as Six Sigma and 8D, and ERP and MRP systems, ideally Oracle NetSuite. You communicate clearly with suppliers, senior management and non-technical colleagues, and you work self-directed, setting your own approach on new assignments and managing several priorities in a fast-paced environment.

You’d be a great fit with:

• Experience thriving in a rapidly changing, fast-scaling start-up environment
• Working knowledge of industry standards such as ANSI, ASTM, AS9100 and AS9102, and of ECJU, UK Dual-Use List, DEFCON and DCC and Cyber Essentials requirements as they apply to suppliers
• Experience with complex optical, electrical or mechanical products in high-technology manufacturing
• Working knowledge of reliability engineering, ESD, calibration and preventive maintenance in a supplier context
• Experience leading cross-functional and supplier teams through systematic improvement, including compliance data collection and sharing with tools such as Power BI
