Collins Aerospace is looking for a Principal Structural Engineer to fill a high business impact role by representing the Engineering organization through tactical and strategic oversight. This experienced Engineer will provide technical expertise throughout the product design, build, and delivery processes for complex, integrated aircraft components of metallic and advanced composite construction. This role will drive meaningful improvements across Engineering Production Support processes by applying a strong understanding of product design, performing detailed structural analyses, and promoting continuous improvement in engineering efficiency, product producibility, quality, and cost reduction. What You Will Do: Perform complex structural analyses using hand and computer calculations, including static, fatigue and fracture analysis of aerospace components. Define, assess, and document repair designs for metallic, bonded metallic, and advanced composite aerospace structures. Work with Materials Review Board (MRB) to develop standard repair instructions. Analyze repair proposals and prepare formal engineering reports supporting minor and major repairs for customers and FAA approval, which may include obtaining authorized engineering signatures. Provide limited direction to others in stress analysis and may act as technical lead on assigned projects. Coordinate repairs with internal and external customers, as well as external staff of major airlines and aircraft manufacturers. Develop and implement processes, methods, and tools that improve efficiency throughout Engineering Production Support workflows activities. Lead and support continuous improvement initiatives focused on engineering quality, productivity, standardization, and cycle time reduction. Assist cross functional technical team in identifying opportunities for improved producibility and working with extended engineering team to implement meaningful changes. Collaborate with Operations, Quality, Manufacturing, and Engineering teams to identify and implement cost reduction opportunities across product lines and processes. Provide technical expertise to Engineering Build Assessment and design study activities to drive regular improvements in defect eradication. Review, quantify, and drive support of defect corrective action plans across the product lines. Support product development teams by providing defect eradication, producibility, and lessons learned early in the product lifecycle. Communicate technical findings, recommendations, risks, and decisions clearly to engineering leadership, customers, and cross functional stakeholders. Ability to travel up to 10% as needed. Qualifications You Must Have: Typically requires a degree in Science, Technology, Engineering or Mathematics (STEM) and minimum 8 years prior relevant experience or an Advanced Degree in a related field and minimum 5 years of experience.
