Principal Additive Manufacturing Design Engineer

At RTX, the world’s largest aerospace and defense company, the Principal Additive Manufacturing Design Engineer will help shape the future of aerospace and defense by applying advanced additive manufacturing (AM) design and engineering expertise. What You Will Do Develop, demonstrate and document design methodologies and tools for additive manufacturing, including conventional CAD and implicit modeling‑based approaches. Enhance design tools through the development of custom modules and scripts. Apply topology optimization to generate geometries enabled by additive manufacturing across structural, thermal, or hydrodynamic domains. Execute Design for Additive Manufacturing (DFAM) projects to support business‑unit evaluation and adoption of additively manufactured components and systems. Define AM software tools and methodologies to interconnect individual tools into a unified toolchain. Establish relationships with government, industry, academia, and RTX Business Units and lead the development of whitepapers, project concepts, and responsive proposals. Provide training and knowledge transfer to RTX Business Units while disseminating best practices to increase the rate of additive adoption. Manage multiple design, development, and demonstration projects. Qualifications Strong understanding of engineering principles and hands‑on experience with laboratory equipment. Ability to work effectively in a multidisciplinary, collaborative team environment focused on innovation. Excellent verbal and written communication skills. University Engineering Degree (or equivalent experience) with at least 8 years of relevant experience, or an Advanced Degree with at least 5 years of experience. Expert CAD user (Siemens NX preferred). Advanced scripting experience with CAD tools, MATLAB, Python, VBA, JavaScript, or similar. Experience with implicit modeling tools such as nTop, including development of custom blocks. Understanding of the AM process using laser powder bed fusion. Experience with finite element analysis (e.g., Ansys, Abaqus, COMSOL). MS or PhD in Mechanical Engineering or a related technical field preferred. U.S. citizenship required; active DoD Secret clearance required. #J-18808-Ljbffr Prattwhitney
