• Coordinate with suppliers and labs for procurement and certification of materials meeting defense standards.
• Recommend advanced coatings, treatments, or bonding strategies for component durability.

Mechanical CAD Design & Simulation:

• Design complex mechanical systems and components using 3D CAD tools (e.g., SolidWorks, Creo).
• Create detailed manufacturing and assembly drawings, applying GD&T and defense-compliant tolerances.
• Perform thermal and structural simulations to assess the reliability of designs.
• Optimize enclosure designs for RF transparency, EMI shielding, and environmental sealing.
• Develop modular assemblies for easy maintenance and field replaceability.

Mechanical System Integration:

• Lead the integration of missile mechanical components into vehicle platforms and ground systems.
• Design and implement mounting strategies that isolate shock and vibration.
• Troubleshoot mechanical, including grounding, shielding, and chassis design.

• Ensure system-level mechanical alignment and tolerance stack-up compliance.

Assembly & Mechanical Fitment:

• Supervise and perform assembly of mechanical sub-systems including missile structural components, and precision mechanisms.
• Verify geometric and weight tolerances, including CG (center of gravity) measurements for integrated systems.
• Develop and refine assembly procedures to reduce error and improve consistency.
• Apply heat dissipation strategies (e.g., heat sinks, airflow optimization, thermal interface materials) in high-power assemblies.
• Ensure all work follows defense QA standards and traceability requirements.

Tooling & Fabrication Oversight:

• Identify tooling requirements for complex assembly and testing processes.
• Oversee the use of mechanical tools, jigs, and fixtures during production.
• Recommend tool improvements for enhanced ergonomics and safety.
• Approve tool calibration cycles and ensure traceability.
• Support decisions on in-house vs. outsourced fabrication based on complexity and cost.

Maintenance & Sustainment Engineering:

• Lead preventive and corrective actions/maintenance for mechanical components in deployed systems.
• Develop upgrade kits and retrofitting solutions for fielded platforms.
• Diagnose failures during routine checks and develop repair strategies.
• Maintain maintenance logs and revision-controlled documentation.
• Collaborate with logistics and field teams to ensure availability of spares and tools.

Standards Compliance & Safety:

• Interpret and apply defense standards including ASTM, AMS, IS, ISO, MIL-STD in design and testing.
• Ensure environmental, ergonomic, and operational compliance of all mechanical components.
• Lead implementation of mechanical safety protocols in assembly and testing zones.
• Review and approve documentation related to risk assessments, hazard analysis, and PPE usage with safety precautions.

Team Mentoring & Technical Reviews:

• Guide junior engineers and technicians on best practices for assembly, testing, and documentation.
• Review peer designs and provide constructive feedback during design and gate reviews.
• Lead knowledge-sharing sessions and develop SOPs for repeatable tasks.
• Promote a safety-first culture and encourage continuous improvement in mechanical processes.

Technical Documentation:

• Generate and review technical documents such as design reports, test plans, and compliance checklists.
• Preparation of MDI,BOM, IPD and QAP etc
• Maintain engineering change logs, ECN/DCRs, and part qualification records.
• Ensure clarity, accuracy, and completeness of installation manuals and maintenance guides.
• Support proposal or bid documentation with mechanical input and specifications.
