Develop and review 3D CAD models, engineering drawings, layouts, bills of material, and mechanical specifications.
Own complex structural calculations, tolerance studies, and mechanical engineering analyses.
Lead FEA and simulation activities for structural, thermal, vibration, shock, and related mechanical performance requirements.
Translate simulation and analysis results into design recommendations, tradeoffs, and product improvements.
Develop and resolve mechanical interfaces between cells, modules, pack structures, cooling systems, electrical assemblies, and enclosures.
Lead mechanical prototype builds, design verification, validation testing, and simulation-to-test correlation.
Lead mechanical root‑cause investigations and develop corrective actions for test, manufacturing, supplier, and field issues.
Apply GD&T, tolerance analysis, and design‑for‑manufacturing and assembly principles to product designs.
Lead mechanical engineering changes through review, validation, and release processes.
Provide technical support for supplier component development, qualification, and resolution of mechanical issues.
Present mechanical analyses, technical risks, design decisions, and recommendations during design reviews.
Drive improvements in product performance, cost, quality, reliability, serviceability, and manufacturability.
Develop and improve engineering methods, analysis standards, and reusable technical tools.
