Product Quality Engineer

Key Responsibilities

• Receive, log, and maintain chain-of-custody for all customer-returned units (bare modules and end-devices); manage sample tracking from receipt through investigation completion.
• Operate the Irvine production lab (LitePoint IQxel + FW) to run full Tx/Rx RF test suites on FA units measuring Tx power, EVM, SEM, PER, and frequency error across MCS/BW/frequency combinations and flash firmware branches from the Systems/Radio teams to execute structured before/after corrective action verification.
• Systematically perform multi-unit failure triage using the module test jig: assess power-on behavior, collect chip serial logs, classify failure modes, and create Jira tickets.
• Conduct component-level fault isolation to determine if failures are at the chip or PCB level.
• Serve as the primary customer-facing contact for all FA cases, acknowledging receipt, setting timelines, and providing data-backed status updates throughout the investigation lifecycle.
• Prepare and issue FA Reports (FARs) to customers, ensuring they are technically accurate and clearly communicate root cause, corrective action, and verification evidence.
• Respond to FAE and customer technical inquiries, translating ongoing lab findings into clear, timely communication appropriate for both technical and non-technical contacts.
• Act as the Irvine-side technical liaison to Design, Systems, Radio, DVT, and Firmware teams, translating lab findings into structured technical briefs and working with FAEs to provide full customer application context that remote engineers can act on asynchronously.
• Maintain Jira FA tickets with complete technical detail, test configurations, firmware versions, BCF files, per-unit results, and failure evidence so remote teams can pick up full context without a live handoff.
• Drive firmware branch requests, root cause assignments, and corrective action commits; follow up proactively to prevent stalls.
• Facilitate cross-site FA review calls preparing agendas, presenting lab findings, capturing action items, and tracking commitments to closure.
• Document all lab test procedures, results, and configurations in Confluence ensuring investigations are fully reproducible, auditable, and accessible to remote engineering teams.
• Prepare internal FA summary reports covering failure pareto, repeat failure patterns, and corrective action verification results for engineering review and management visibility.

Qualifications

• Hands-on RF production test experience operating LitePoint IQxel or equivalent, running Tx/Rx test suites, flashing firmware builds, configuring BCF/test region settings, and executing before/after comparisons for corrective action verification.
• Demonstrated module-level failure triage experience: power-on jig assessment, chip serial logging, multi-category failure classification, and Jira-based tracking with engineering team routing.
• Demonstrated experience owning customer FA investigations end-to-end from unit receipt through root cause, corrective action verification, and FA Report delivery.
• Strong technical writing skills: clear customer-facing FA reports and structured internal investigation documents.
• Effective cross-time zone communication: experience working with distributed engineering teams with a disciplined async-first, Jira/Confluence documentation approach.
