We are looking for a Product Engineer to own the production health of millimeter-wave (mmWave) RF Digital Beamforming (DBF) and RF front-end ASICs in high-volume manufacturing for our customer terminal and satellite products.
This is a data-driven, decision-making role. You will own end-to-end production for assigned ASICs and be the engineer accountable for whether material ships. You will work in a fast-moving, cross-disciplinary team to own yield and ensure high quality, maintain test program health across various products, debug issues with fab/OSAT partners, and drive on-going reliability efforts.
Key job responsibilities
Yield and lot disposition
• Own yield for assigned products across fab, bump, wafer sort, assembly and final test, and drive improvement against entitlement.
• Analyze WS and FT data to identify outliers, wafer map signatures and parametric drift.
• Make lot disposition decisions on held material, release, re-screen or scrap, and document the basis for each.
• Own OCAP response for SPC and yield excursions, and close corrective actions with the foundry and OSAT.
• Define and maintain outlier screening rules including SBL, SYL, PAT and geographical ink-out.
Test program, limits and test hardware
• Own production test limits, including limit proposals, GR&R guard-banding and coverage changes.
• Balance test coverage against test time, UPH and cost per unit, and drive test cost reduction.
• Own probe card and load board qualification and buy-off, including calibration tracking and first-pass buy-off rate.
• Work with Test Engineering to validate test program revisions before production deployment.
Production data systems and reporting
• Build and maintain automated WS/FT reporting, yield dashboards and KPI tracking.
• Develop analysis routines to automate reporting, and flag anomalies.
• Maintain die-level traceability from bump through final test.
• Present yield, quality and production status in weekly reviews and quarterly business reviews.
Quality, RMA and failure analysis
• Lead root cause investigation on QA failures, RMA returns and field escapes, and drive cases to closure.
• Own 8D and corrective action reporting for customer-facing quality events.
• Coordinate with external FA labs for physical analysis including TEM, SEM, FIB, OBIRCH, EMMI and lock-in thermography.
• Work with Design and Test to determine whether a failure is product, process or test related, and verify corrective action effectiveness.
Qualification and change management
• Qualify supplier-initiated Process Change Notifications and second-source material, comparing control against change material at the margin level rather than against test limits alone.
• Define sample plans, stress conditions and acceptance criteria per JEDEC standards.
• Own qualification status documentation and product reliability records.
Cross-team and OSAT collaboration
• Act as the production engineering interface to OSAT and foundry partners on yield, quality and test issues.
• Support production readiness reviews, production transfer checklists and new product introduction.
