Reproduce and document suspected product issues with complete environment, version, configuration, expected behavior, observed behavior, evidence, business impact, and steps to reproduce. Partner with Engineering, Quality, Offering Management, Sales, Cybersecurity, and Technical Publications to validate fixes, clarify limitations, improve documentation, and communicate practical workarounds. Create and maintain troubleshooting articles, application notes, FAQs, configuration examples, technical guidance, case notes, and training materials. Deliver or support technical demonstrations, customer and dealer training, onboarding, and team knowledge-transfer sessions. Manage several active cases and commitments with accurate status, ownership, priority, next steps, and closure documentation. Identify recurring case drivers and recommend improvements to products, processes, tools, documentation, warnings, or training. Follow applicable quality, cybersecurity, data-protection, confidentiality, export-control, record-retention, and safety requirements.
