The Lockheed Martin Next Generation Interceptor (NGI) team is seeking a Sustainment Engineer Sr. – Maintenance Concepts & Supportability to work from our Huntsville, AL location.

This position supports the development and integration of missile maintenance concepts, technical procedures, and supportability solutions for the NGI missile defense system. The role focuses on applying practical missile maintenance knowledge to the development of in-silo maintenance capabilities, technical assessments, and system development activities.

The position will collaborate with Systems Engineering, Design Engineering, Manufacturing Engineering, Reliability Engineering, and Product Support teams to ensure maintenance requirements and operational considerations are addressed throughout system development.

We are seeking a technically experienced professional with hands‑on missile maintenance experience who can translate practical maintenance knowledge into clear, accurate, and executable technical procedures.

The ideal candidate understands military missile maintenance operations, can gather technical information from subject matter experts, interpret engineering documentation, and work effectively with multidisciplinary engineering teams. Experience gained through military service, government organisations, or the aerospace and defence industry is highly relevant.

• Develop and evaluate in‑silo missile maintenance concepts, processes, and technical approaches, considering operational constraints, safety, equipment needs, and system requirements.

• Gather and evaluate technical information from maintenance SMEs, engineering documentation, and equipment knowledge to develop, write, and revise maintenance procedures, work instructions, and supporting technical products.
• Ensure maintenance documentation is accurate, repeatable, technically sound, and aligned with applicable requirements.

• Support the identification and integration of missile maintenance requirements throughout system development.
• Participate in technical reviews, maintenance demonstrations, and verification activities to evaluate maintenance feasibility and identify potential issues.

• Collaborate with Manufacturing Engineering and other technical teams to address maintenance procedures, tooling, support equipment, and system interfaces.
• Communicate maintenance challenges and recommend practical solutions to engineering and program stakeholders.

• Evaluate maintenance processes and operational considerations to identify risks, improve maintainability, and support long‑term system readiness.

• Experience supporting the maintenance, inspection, repair, troubleshooting, or sustainment of military or DoD missile systems or associated missile support equipment.
• Experience gathering technical information from subject matter experts (SMEs) and translating complex or undocumented maintenance processes into clear, accurate, and repeatable technical procedures, work instructions, or other technical documentation.
• Demonstrated hands‑on experience personally developing, writing, or substantially revising technical maintenance procedures, work instructions, or related technical documentation based on equipment knowledge, maintenance activities, or information obtained from subject matter experts.
• Experience interpreting and applying technical manuals, engineering drawings, specifications, or military technical orders.
• Familiarity with military maintenance practices, safety requirements, and configuration‑controlled…
