Sr. Product Quality Engineer

UST; Singapore; On-site; SGD 90,000 - 150,000; Full time

Job summary

UST is seeking a hands-on system-debug engineer to own SLT and platform quality for embedded x86 products. You will investigate customer-return and factory-reported failures, reproduce complex issues, and drive corrective actions with design, validation, firmware, BIOS, and manufacturing teams.

The role requires strong experience with UART/JTAG, oscilloscopes, Linux, and scripting (Python/C++). You will mentor others, establish scalable debug methodologies, and communicate findings to engineers

Qualifications

• Hands-on system-debug experience with SLT and bring-up.
• Experience diagnosing boot issues and platform failures.
• Strong understanding of silicon-to-system stack.

Responsibilities

• Own or lead SLT debugging for customer and factory failures.
• Analyze boot errors, hangs, crashes, and reliability issues.
• Collect logs and diagnostics to guide root-cause actions.
• Design experiments and tests to prove hypotheses.
• Collaborate across teams to improve diagnostics and test stability.
• Prepare technical reports communicating conclusions and actions.
• Mentor engineers in system-debug and root-cause methods.

Job description

The engineer will be responsible for System-Level Test (SLT) debug, platform quality engineering and failure analysis for Embedded x86 SoC products. The role investigates customer-return and factory-reported failures, reproduces complex system-level issues, isolates root causes and drives corrective and preventive actions with Design, Validation, Firmware, BIOS, Product Engineering, Manufacturing and Failure Analysis teams.

The engineer will use SLT infrastructure, platform diagnostics, firmware and operating-system logs, system characterization and structured root-cause methods to improve product quality, reliability, manufacturing effectiveness and customer experience.

THE PERSON

The ideal candidate is a hands-on system-debug engineer with strong experience in SLT, platform bring-up, embedded x86 diagnostics, failure reproduction and customer-return analysis. The candidate should understand the complete product stack, including silicon, package, board, power delivery, BIOS/UEFI, firmware, operating system, drivers and workloads. More senior candidates are expected to establish scalable debug methodologies, lead cross-functional investigations, influence product-quality decisions and mentor experienced engineers.

KEY RESPONSIBILITIES

• Own or lead SLT debug for customer-return, qualification and factory-reported failures.
• Analyze boot failures, POST errors, hangs, resets, crashes, performance anomalies, device-enumeration issues and reliability failures.
• Collect and interpret serial-console output, firmware traces, event logs, kernel logs, crash data, diagnostic results and platform telemetry.
• Generate hypothesis and able to come up with experiments and electrical tests to prove the hypothesis for observed failures
• Work with cross-functional teams to improve SLT coverage, diagnostics, automation, screening effectiveness, test stability, cycle time and failure triage.
• Prepare clear technical reports and communicate conclusions, risk and recommended actions to engineering, management and customer-quality stakeholders.
• Lead cross-functional technical initiatives appropriate to the assigned job level and mentor engineers in system-debug and root-cause methods.

PREFERRED EXPERIENCE:

• Hands-on experience developing, executing or debugging system-level tests (UBUNTU or WINDOWs based) for x86 platform (desktop, industrial PC, server, or embedded x86 devices).
• Strong knowledge of x86 platform architecture, system boot flow and interactions among CPU, memory, storage, PCIe, USB and network interfaces.
• Experience with BIOS/UEFI, firmware initialization, POST-code interpretation, serial-console debug and operatingsystem boot troubleshooting.
• Knowledge of using system-debug instruments and interfaces such as UART, JTAG, oscilloscopes, logic analyzers and platform power or signal measurements.
• Proficiency in Linux command-line environments and at least one relevant language: Python, C/C++, Perl or Bash.
• Experience integrating AI agents into daily workflows is highly desirable.

ACADEMIC CREDENTIALS & EXPERIENCE

BS with 5+ years, MS with 3+ years, or PhD with 0-1+ years of relevant experience.
