A Quality Engineer is a professional responsible for ensuring that products meet specific quality standards before they are released to customers. They develop and implement testing processes, analyze data, and identify areas for improvement. Their work helps to minimize defects and enhance customer satisfaction. Quality Engineers often collaborate with other teams, such as manufacturing, design, and supply chain, to ensure that quality is maintained throughout the production process. They may also use various tools and methodologies, including Six Sigma and ISO standards, to assess and improve product quality effectively.
