• Expert‑level proficiency using SolidWorks or equivalent 3D CAD platforms.
• Extensive experience applying thermal management techniques including conduction, convection, radiation, airflow management, heatsinks, thermal interfaces, and environmental derating.
• Strong understanding of structural mechanics, vibration, fatigue, shock loading, mechanical reliability, and environmental robustness.
• Proven experience using simulation and analysis tools to support product development and design validation.
• Experience supporting environmental qualification testing and reliability verification activities.
• Strong knowledge of sheet metal, machined, cast, moulded, fabricated, and injection‑moulded component design.
• Strong understanding of GD&T, tolerance analysis, materials selection, DFMA, and engineering best practices.
• Experience managing product structures, BOMs, engineering documentation, and design releases within PLM systems.
• Hands‑on experience working with PLM and ERP systems such as Oracle Agile PLM, Oracle Cloud PLM, Windchill, Teamcenter, Arena, or similar platforms.
• Experience using SolidWorks PDM, Autodesk Vault, or similar engineering data management systems for revision control, configuration management, and product releases.
• Strong experience managing ECR, ECO, ECN, deviation, waiver, and product release workflows.

Responsibilities

• Lead the mechanical design and development of complex electromechanical products, assemblies, enclosures, and mounting systems.
• Own enclosure and assembly designs from concept through production release, ensuring performance and cost objectives are met.
• Develop detailed 3D CAD models, assemblies, drawings, specifications, and documentation.
• Perform tolerance analysis, GD&T, and DFMA assessments.
• Conduct thermal, structural, shock, vibration, and modal analyses using analytical and simulation methods.
• Lead thermal management design activities for embedded electronics and power systems.
• Develop and validate mitigation strategies for thermal and environmental stresses.
• Support environmental qualification activities including vibration, IP, humidity, and life testing.
• Work with cross‑functional teams to ensure successful product integration.
• Drive root‑cause investigations and corrective actions for mechanical and reliability issues.
• Support supplier selection, manufacturing readiness, and cost optimisation initiatives.
