About the Role:

We are seeking a highly skilled Senior Engineering Lab Technician to support advanced hardware validation, power electronics testing, and lab operations for next-generation semiconductor and power delivery systems.

This role is ideal for a hands-on technician with strong lab discipline, excellent troubleshooting skills, and experience supporting hardware bring-up in a fast-paced R&D environment. The Senior Lab Technician will work closely with PMIC designers, systems, and test engineers to execute validation activities, maintain lab readiness, improve test efficiency, and support production-readiness efforts for next-generation power delivery and semiconductor systems.

Key Responsibilities:

Hardware Bring-Up, Validation & Debug

• Support board-level bring-up of power electronics and semiconductor-based hardware.

• Execute validation, characterization, and reliability testing based on engineering test plans.

• Assist engineers with debug of power converters, evaluation boards, test fixtures, and prototype hardware.

• Capture, organize, and summarize test data, waveforms, and observations clearly and accurately.

• Identify abnormal behavior, document issues, and support root-cause investigation.

Soldering, Rework & Prototype Support

• Perform fine-pitch soldering, component replacement, board rework, and prototype assembly.

• Support engineering change implementation on prototype boards and test fixtures.

• Inspect boards and assemblies for workmanship, damage, solder defects, or handling issues.

• Coordinate with engineering on rework priorities and documentation.

Lab Test Execution & Automation Support

• Set up and operate lab equipment including oscilloscopes, DMMs, power supplies, electronic loads, function generators, and data acquisition systems.

• Support automated test setups using tools such as Python, LabVIEW, MATLAB, or similar platforms.

• Help improve test throughput, repeatability, documentation, and lab workflow efficiency.

• Build, modify, and maintain test fixtures and evaluation setups.

Lab Operations & Infrastructure

• Own daily lab operations, including equipment setup, organization, calibration tracking, maintenance, and troubleshooting.

• Maintain a safe, clean, and ESD-compliant lab environment.

• Manage lab inventory including cables, probes, fixtures, components, tools, and consumables.

• Support incoming hardware inspection, labeling, tracking, storage, and controlled checkout/return processes.

• Help define and enforce best practices for lab usage, equipment handling, safety, and documentation.

Cross-Functional Collaboration

• Partner closely with chip designers, power electronics engineers, test engineers, digital designers, and operations teams.

• Support engineering validation and production-readiness activities.

• Help establish disciplined lab practices.

• Communicate clearly on test status, lab constraints, equipment issues, and technical observations.

Required Qualifications:

• 3-5+ years in hardware lab or R&D environment

• Strong hands-on experience with lab equipment such as oscilloscopes, DMMs, power supplies, electronic loads, function generators, and thermal test equipment.

• Experience supporting hardware bring-up, debug, validation, or characterization.

• Strong soldering, rework, and prototype modification skills.

• Familiarity with at least one automation or data analysis tool such as Python, LabVIEW, MATLAB, or similar.

• Ability to read schematics, follow test procedures, and understand basic electrical measurements.

• Strong troubleshooting skills and attention to detail.

• Comfortable working with high-current, low-voltage, and sensitive electronic hardware.

• Strong organizational skills and ability to maintain lab discipline in a fast-paced environment.

Preferred Qualifications:
