The role is responsible for evaluating product performance, identifying opportunities for improvement, and implementing design modifications where required.
Key Responsibilities:
• Apply sound engineering principles, analytical techniques, and industry standards to perform accurate calculations that support product design, development, performance verification, and compliance requirements.
• Evaluate design assumptions, identify potential risks, and provide technically robust recommendations to support decision-making throughout the product lifecycle.
• Develop clear and comprehensive technical specifications for engineering projects, products, and tooling, ensuring requirements are accurately defined, achievable, and aligned with customer, regulatory, and business needs.
• Produce and maintain accurate quality assurance documentation, test records, inspection reports, and compliance evidence to support internal quality processes and external customer requirements.
• Participate actively in product development reviews with the Engineering Manager, providing technical insight, progress updates, risk assessments, and recommendations to support informed project decisions.
• Conduct inspections of products and assemblies during manufacture and development to verify compliance with drawings, specifications, quality standards, and project requirements.
• Respond professionally and accurately to client technical enquiries, providing expert advice, troubleshooting support, and practical solutions to engineering challenges.
• Prepare, review, and maintain technical literature, including operating instructions, technical manuals, product specifications, test reports, and engineering documentation.
• Maintain comprehensive and organised technical files, ensuring all design records, calculations, drawings, specifications, test results, and validation documentation are controlled, current, and readily accessible.
• Support traceability, compliance, and knowledge retention through effective document management practices.
• Interpret test data and provide evidence-based recommendations for product acceptance, modification, or further investigation.
• Identify opportunities for product enhancement, cost reduction, improved manufacturability, increased reliability, and enhanced customer satisfaction.
