About The Position

L3Harris is seeking a highly skilled and dynamic senior Mechanical Engineer to support customer-funded programs and internal research efforts within our Space, Superiority and Imaging Division. Our Intelligence, Surveillance, and Reconnaissance solutions serve a broad array of government, civil, and commercial customers by enhancing information superiority, contributing to our national security and providing actionable data for the protection of property and human life. We specialize in high-reliability airborne and space-based remote sensing payloads that offer active and motion imaging and data processing, exploitation and dissemination. We also provide solutions that map and monitor the earth for a variety of commercial and governmental users. The Mechanical Engineer will perform design, development, analysis, and manufacturing tasks on complex mechanical hardware including precision space structures and mechanisms in a program team environment. This role involves program support and technical leadership over requirements definition, concept generation, material and finish selection, trade studies, design sensitivity/optimization studies, preliminary and detailed design, design sensitivity and tolerance analysis, design documentation, Bill of Materials (BOM) management, and assembly/integration and testing. The candidate must be an expert in 3D modeling, design for manufacturing, and possess the ability to work independently or within a multi-disciplined team environment. In this role, the candidate will design high-precision and complex space opto-mechanical telescopes hardware as part of an Integrated Product Team (IPT). Hardware variety spans machined components, composite structures, deployable mechanisms, opto-mechanical support structure, bearings, capital tooling and fixturing, and launch mechanisms. The candidate will leverage high reliability, flight-proven, heritage design concepts to produce high quality designs within an aggressive timeline. They will lead and participate in technical team reviews and technical review boards, interface with outside suppliers/customers and other engineering disciplines (Structural, Thermal, Electrical, Manufacturing, Integration and Testing, Quality, Configuration Management), and present design details at program reviews to customers and independent reviewers. The role also includes developing and performing testing to show proof-of-concept and/or qualification of new designs, supporting production operations with the design of tooling, test equipment, and shop aids, and providing regular status updates to Program Management and Project Engineers on cost and schedule performance.
