• 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.
• Experience developing customer‑specific product modifications, configurable product variants, and engineered solutions for industrial products.
• Experience conducting root‑cause analysis and resolving complex product design, manufacturing, and field issues.
• Strong analytical, troubleshooting, leadership, and technical communication skills.
• Ability to work independently while contributing effectively within cross‑functional engineering teams.

Responsibilities

• Lead the mechanical design and development of complex electromechanical products, assemblies, enclosures, and mounting systems used in demanding industrial and utility environments.
• Own enclosure and assembly designs from concept through production release, ensuring performance, manufacturability, serviceability, reliability, and cost objectives are achieved.
• Develop detailed 3D CAD models, assemblies, manufacturing drawings, specifications, and engineering documentation.
• Perform tolerance analysis, stack‑up analysis, geometric dimensioning and tolerancing (GD&T), and Design for Manufacture and Assembly (DFMA) assessments.
• Conduct thermal, structural, shock, vibration, and modal analysis using analytical and simulation‑based methods.
• Lead thermal management design activities for embedded electronics, communications equipment, industrial computing platforms, sensors, and power electronics.
• Develop and validate mitigation strategies for thermal, shock, vibration, transportation, and environmental stresses affecting product performance and long‑term reliability.
• Support environmental qualification activities including vibration, shock, ingress protection (IP), temperature cycling, humidity, transportation, and accelerated life testing.
• Work closely with Electrical, Firmware, Software, Systems, Manufacturing, and Quality teams to ensure successful product integration.
• Drive root‑cause investigations and corrective actions related to mechanical, thermal, reliability, manufacturing, and field performance issues.
• Support supplier selection, manufacturing readiness, value engineering, and cost optimisation initiatives.
• Own mechanical product structures, Bills of Materials (BOMs), drawings, specifications, and engineering documentation throughout the product lifecycle.
• Drive Engineering Change Requests (ECRs), Engineering Change Orders (ECOs), Engineering Change Notices (ECNs), deviation requests, and product release activities in accordance with company processes.
• Lead change impact assessments covering product performance, manufacturability, cost, quality, supply chain, reliability, compliance, and installed‑base considerations.
• Ensure accurate configuration management and control of mechanical designs through PLM, ERP, PDM, and engineering data management systems.
• Support Sales, Product Management, and Application Engineering teams in evaluating customer‑specific requirements, special modifications, and product variation requests.
• Develop practical enclosure concepts, assembly modifications, and configurable product variants that meet customer requirements while maintaining reliability, manufacturability, compliance, and lifecycle supportability.
• Assess technical and commercial impacts of customer‑specific modifications, including cost, schedule, tooling, qualification, certification, manufacturing, and service implications.
• Support proposal and quotation activities through concept development, feasibility assessments, engineering estimates, and solution reviews.
• Drive standardisation and modular design approaches that maximise customer flexibility while minimising unnecessary product variation.
• Leverage advanced simulation, modelling, automation, and AI‑assisted engineering tools to improve product quality and accelerate development activities.
