Tech Lead Mechanical Design (Electro-Optical Systems)

Key Responsibilities

Leadership & Project Ownership

• Lead and mentor a team of mechanical design engineers, providing guidance on design methodologies, standards, and best practices.
• Manage team performance, facilitate technical and soft skill development plans, and foster a collaborative, innovative culture.
• Own the complete mechanical design life cyclefrom concept, feasibility, prototyping, to production release.
• Prepare project schedules, track progress, and provide status updates to management.
• Foster innovation within the team by exploring new materials, manufacturing processes (CNC, additive manufacturing, injection molding), and costeffective solutions.
• Set strategic direction for mechanical design innovations and future capabilities to support evolving product and market needs.
• Ensure design data and intellectual property are protected in line with defense cybersecurity standards and company IP policies.

Mechanical Design & Development

• Execute and review 3D mechanical designs using CAD tools (SolidWorks, CATIA, Creo, NX) for weapon upgradation kits (buttstocks, pistol grips, rails, helmet mounts) and electro-optical assemblies.
• Design for manufacturability: injection molding (draft, wall thickness, undercuts, parting lines, ribs), machining, casting, and sheet metal parts.
• Conduct design analysis (thermal, stress, fit/form, IP, IK parameters) and perform FEA (ANSYS, Abaqus) as needed.
• Generate detailed design documentation: manufacturing drawings, exploded stack-ups, assembly guides, and BOMs.
• Manage suppliers and vendors for prototype development and component manufacturing.
• Troubleshoot and resolve design issues during development, testing, and production phases.

GD&T (Geometric Dimensioning & Tolerancing)

• Apply and interpret

  GD&T principles

  (ASME Y14.5 or ISO standards) in all drawings to ensure functional fit, form, and interchangeability.
• Define and review critical dimensions, datum structures, and tolerances for manufacturability and inspection readiness.
• Conduct tolerance stack-up analysis and support first-article inspections, CMM measurements, and PPAP reviews.

Design Reviews & Compliance

• Conduct design reviews (DFMEA, PFMEA, DVP&R) and ensure robust design processes.
• Ensure all designs comply with regulatory, safety, and environmental standards (RoHS, REACH, MILSTD if applicable).
• Present concepts and finalized designs in internal and external stakeholder reviews.
• Lead mechanical aspects during field trials, gather user feedback, and iterate designs to improve ergonomics, durability, and mission-readiness.

Cross-Functional Collaboration & Support

• Coordinate with crossfunctional teams (Electrical, Electronics, Firmware, Manufacturing, QA) to ensure seamless product integration.
• Collaborate with Engineering & SCM teams for project execution, timelines, and material readiness.
• Coordinate with OEMs for technical documentation, compliance certificates, authorizations, and tender QRs.
• Support product demonstrations, exhibitions, and client interactions as required.

Design Enhancement & Sustenance

• Modify and update existing product designs to meet evolving technical or client requirements.
• Perform root cause analysis on field/production issues and develop corrective test procedures.
• Optimize mechanical production techniques, incorporating DFMA (Design for Manufacturing & Assembly).
• Finalize and maintain mechanical BOMs, ensuring accurate SAP uploads and case tracking.

Knowledge Building & Continuous Development

• Conduct technical studies on optical/mechanical systems, thermal imaging, night vision, and firmware integrations.
• Maintain an updated repository of datasheets, specs, presentations, case histories, and product brochures.

Required Qualifications & Skills

• Bachelors or Master’s degree in Mechanical Engineering or equivalent.
• 8–12 years of mechanical design experience in precision electro-optical or defense-grade systems, with at least 3 years in a lead or senior role.
• Proven ability to lead mechanical projects and drive cross-functional deliverables.
• Strong hands-on experience with 3D CAD tools (SolidWorks, Creo, CATIA, NX) and surfacing techniques (boundary surface, loft, fill, etc.).
• Expertise in applying

  GD&T (ASME Y14.5 or ISO standards)

  for production drawings, inspection plans, and tolerance stack-up.
• Proficiency in FEA tools (ANSYS, Abaqus) and thermal/structural analysis.
• Knowledge of manufacturing processes: machining, casting, sheet metal, plastic molding.
• Strong understanding of product life cycle management (PLM) systems.
• Excellent leadership, communication, and interpersonal skills.
• Ability to manage multiple projects and prioritize tasks in a fast-paced environment.
• Experience in design for manufacturability, supplier development, and rapid prototyping.
• Working knowledge of SAP, ERP systems, and documentation protocols.

Desirable Skills

• Exposure to ISO standards & military standards (MIL-STD-810/883, JS 55555) or ruggedization.
• Knowledge of weapons, thermal cameras, and night vision sensor devices.
• Experience working with Govt Labs, OEMs, Defense Integrators, and product certification authorities.
