Electrical PCBA Sustaining Engineer

To make electronics, you need chips, wafers, transistors, reticles, and... To make these, you must see, test and manufacture them at scale-faster and better than ever before. That's where KLA comes in. Whether you're early in your career or an experienced professional, you'll solve complex challenges, work alongside brilliant minds and help shape the future of technology.

Group/Division

The KLA Services team consists of Service Sales, Marketing, Spares Supply Chain Management, Field Operations, Engineering, Product Training, Digital Solutions and Analytics, and Technical Product Support.

What You'll Do

In this role, you will play a key part in advancing business priorities by delivering high-impact work across your area of expertise. Perform hands-on diagnosis, troubleshooting, and repair of complex electronics at the PCB and board level to support KLA products throughout their lifecycle. This role requires strong technical capability in PCBA failure analysis, the ability to work through circuit-level problems with limited design documentation, and close collaboration with senior engineers and cross-functional teams to deliver timely, high-quality repair solutions.

Key Responsibilities

• Diagnose and troubleshoot defective PCBAs using oscilloscopes, multimeters, logic analyzers, and related lab equipment.
• Conduct PCBA design analysis (reverse engineering) to understand circuit intent and failure modes, building toward reverse engineering capability.
• Troubleshoot PCBA issues with limited or no design documentation, applying critical thinking and systematic debugging techniques.
• Perform board-level failure analysis on analog, digital, and mixed-signal circuits, working with senior engineers when issues span sub-system boundaries.
• Support the development of board diagnosis, troubleshooting, and repair plans — including contributing to approach definition, timeline estimation, and identification of technical dependencies.
• Support engineering change orders (ECOs) with technical justification and cross-functional coordination.
• Contribute to root-cause analysis and corrective action implementation, with increasing independence on moderate-complexity problems.
• Collaborate with cross-functional teams (systems, software, manufacturing, service, supply chain) to support issue resolution.
• Support technical engagement with external vendors on issue resolution and repair readiness.
• Develop and maintain engineering documentation including test procedures, troubleshooting guides, and repair records.
• Engage with suppliers to train them on board troubleshooting, repair execution trainings.
• Communicate progress, findings, and risks clearly to both technical and non-technical stakeholders.
• Work effectively with junior and senior team members in a collaborative environment.
• Travel for escalations as needed, primarily to Singapore and China.

Preferred Qualifications

• Bachelor’s or Master’s degree in Electrical Engineering, Electronics Engineering, or related discipline
• 7+ years of experience in electronics develop, sustaining engineering, or board-level sub-system support
• Demonstrated ability to independently resolve complex board and sub-system level issues
• Strong expertise in analog and digital circuit design principles and hands-on PCBA troubleshooting
• Proven experience driving root-cause analysis, corrective actions, and ECO execution
• Strong written and verbal communication skills with the ability to influence cross-functional teams
• Minimum Qualifications Master's Level Degree and 3 years related work experience; Bachelor's Level Degree and related work experience of 5years; or equivalent work experience
