Electrical Hardware PCBA 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. Our services organization maximizes the value of our customers' KLA assets – with highly trained service and product support engineers providing installation services and 24/7 technical support and parts delivery through our extensive supply chain network.

What You'll DoIn 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 discipline7+ 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…
