We seek an experienced Sr. Principal Mechanical Engineer (T4) to join our team within the Intelligence Systems Business Unit. The successful candidate will independently lead mechanical design, analysis, integration, and testing for RF and EO aperture and payload structure design supporting multiple high-profile satellite programs. This role is ideal for a technically accomplished and strategic engineer who thrives in fast-paced, multidisciplinary environments and is eager to take leadership responsibility beyond foundational design activities.

• Lead end-to-end mechanical design and development of advanced antenna and electro-mechanical sensor sub-assemblies through all product lifecycle phases: concept, detailed design, fabrication, integration, test, and delivery
• Develop high-fidelity 3D CAD models (Creo or Siemens NX), and generate aerospace-compliant engineering documentation
• Identify, assess, and mitigate technical risks; support troubleshooting and root-cause analysis during integration and testing
• Drive incorporation of digital engineering practices, including Agile/Dev Ops methodologies, Model-Based Systems Engineering (MBSE), simulation, and data analytics to improve engineering rigor and efficiency
• Independently determine technical objectives and solutions, exercising substantial latitude in problem-solving complex and novel engineering challenges
• Collaborate closely with cross-functional teams—electrical, thermal, structures, manufacturing—to ensure subsystem compatibility and manufacturability
• Support and contribute to proposal technical volumes, technology roadmap creation, and process improvement initiatives within the department
• Engage with customers and senior leadership in technical presentations, briefings, and program reviews, clearly articulating design rationale and status
• Mentor junior level engineers, facilitate knowledge transfer, and contribute to a culture of continuous improvement
• Maintain configuration and compliance with applicable quality, security (TS/SCI clearance), and industry standards

• Bachelor’s degree in STEM with 8 years of experience, a master’s degree with 6 years of experience or a PhD with 3 years of experience in Mechanical Engineering, Electrical Engineering, Computer Engineering, Computer Science, or related technical fields
• U.S Citizenship is required
• No clearance required to start, but must have the ability to obtain and maintain a TS/SCI clearance
• Working knowledge of materials, specifications, manufacturing processes and design tools utilized for antenna panel and supporting electronics assemblies
• Proven proficiency with mechanical hardware design in RF/EO sensor or antenna assemblies, including electro-mechanical subsystems and electronic packaging
• Expert-level use…
