  • Participate in and, when appropriate, lead design reviews, technical trade studies, risk assessments, root-cause investigations, and failure analyses.
  • Support product development throughout the lifecycle, including concept development, detailed design, prototyping, testing, release, production, certification, and sustainment.
  • Perform hands-on engineering activities, including prototype fabrication, test setup and execution, troubleshooting, data collection, and operational support for company products.
  • Identify technical risks, incomplete requirements, design weaknesses, and engineering issues and develop effective solutions.
  • Contribute to improvements in product quality, manufacturability, reliability, maintainability, cost, and development efficiency.
  • Contribute to the development and improvement of engineering methods, tools, templates, calculations, and processes.
  • Collaborate with manufacturing, quality, supply chain, program management, and other engineering disciplines to resolve technical issues and deliver products successfully.
  • Ensure designs comply with applicable aerospace standards, customer specifications, regulatory requirements, and company quality standards.
  • Contribute to engineering schedules, estimates, resource planning, and technical execution plans.
  • Evaluate and apply appropriate design tools, materials, technologies, analysis methods, and manufacturing approaches for aerospace applications.
  • Follow configuration management, engineering change, document control, and other required engineering processes.
  • Review technical work for accuracy, completeness, compliance, and practical application.
  • Provide technical guidance and mentorship to less-experienced engineers and technicians when appropriate.
  • Participate in customer meetings, technical reviews, audits, and presentations.
  • Promote a culture of engineering rigor, safety, quality, accountability, and continuous improvement through consistently high-quality work.
