The Customer Quality & RMA Engineer serves as the primary technical interface between Infinitum and its customers on all quality-related matters — including field complaints, warranty returns, RMA processing, corrective action management, and customer-facing quality reporting. This role owns the complete RMA lifecycle from customer notification through root cause resolution and verified closure, and is responsible for ensuring that every customer quality event is investigated with rigor, communicated with transparency, and resolved permanently.

• Own the end-to-end RMA process — from initial customer notification through receipt, inspection, root cause analysis, corrective action, and verified closure
• Triage and prioritize incoming field complaints and warranty returns based on customer impact, failure mode severity, and strategic account importance
• Conduct or coordinate physical inspection and failure analysis of returned motors and assemblies
• Maintain accurate, real-time RMA tracking data including cycle time, failure mode distribution, and cohort maturity trends
• Communicate RMA status, findings, and corrective actions to customers in a professional, timely, and technically credible manner
• Drive RMA rate reduction through systemic root cause analysis and closed-loop corrective action — targeting the structural elimination of recurring failure modes

• Serve as the primary quality point of contact for assigned customer accounts — including hyperscale data center customers and industrial OEM partners
• Lead customer quality reviews, corrective action presentations, and quality performance reporting
• Manage customer-specific quality requirements, special controls, and approval processes including First Article Inspection (FAI) and Production Part Approval Process (PPAP) where applicable
• Respond to customer quality escapes with urgency — initiating containment within 24 hours and providing 8D corrective action reports within agreed customer timelines

• Distinguish containment actions (immediate customer protection) from permanent corrective actions (root cause elimination) and manage both with discipline and documentation rigor
• Verify effectiveness of corrective actions through defined measurement periods before formal closure
• Drive yokoten — horizontal deployment of lessons learned across product lines, manufacturing sites, and suppliers where the same failure mode could recur
• Maintain a corrective…
