Senior System Integration Engineer - Test & Validation

Halo Industries•Santa Clara, CA

About The Position

Halo Industries, Inc., a pioneer in manufacturing innovation with light-based technologies, seeks a highly skilled System Integration Engineer to join our dynamic team. Our proprietary advancements replace traditional processes with novel light-based equivalents, offering higher quality, lower cost, and enhanced functionality. As we rapidly expand our operations, we're looking for a team to oversee our prototype systems' integration and verification activities. We are seeking a highly motivated and skilled Senior System Integration Engineer – Test & Validation to join our dynamic team. This role is crucial for the successful integration, testing, and deployment of our cutting-edge laser-based wafer manufacturing systems. The ideal candidate will have deep hands-on experience with complex electro-mechanical and optomechanical hardware, including lasers, motion stages, and control electronics, and will be responsible for ensuring that all system components perform to specification through rigorous test and validation. This position requires a strong understanding of system-level hardware integration, and test automation, along with the ability to diagnose issues across electrical, mechanical, and optical domains. This is a hardware-focused documentation, test, and validation role – ideal for an engineer passionate about working directly with instrumentation, sensors, and high precision actuators to drive reliability and performance improvements in a fast-paced manufacturing environment.

Requirements

Bachelor’s degree in Mechanical Engineering, Optical Engineering, Electrical Engineering or a related field.
5+ years of experience in hardware system test, validation, or system engineering within semiconductor equipment, laser systems, robotics, or precision automation.
Demonstrated ability to troubleshoot complex hardware systems, isolate issues, and drive corrective actions in collaboration with design engineers.
Proven ability to plan, execute, and document hardware validation efforts from concept through system acceptance.
Strong hands-on background with electromechanical systems, including controls, sensors power electronics, and optical assemblies.
Experience developing and maintaining ATP documents, test procedures, and build instructions for complex systems.
Proficient with instrumentation and diagnostics tools (Oscilloscope, DMM, DAQ’s, interferometers, alignment cameras, etc.)

Nice To Haves

Experience in a hands-on lab or factory setting, working alongside technicians to build, test and qualify hardware systems.
Experience with laser systems and optical alignment, including beam path setup, diagnostics, and calibration.
Familiarity with semiconductor wafer manufacturing equipment, process flow, or fab environment practices (vacuum, cleanroom or safety protocols).
Working knowledge of hardware test automation using tools for system characterization.
Exposure to motion control and optomechanical systems, including tuning, encoder calibration, and vibration analysis.
Experience developing or executing Acceptance Test Procedures (ATP’s) and formal system-level validation plans.
Proficiency with data analysis and visualization for performance trending and reliability studies.
Familiarity with data-acquisition and control software (LabVIEW, Python, MATLAB, or similar) for test automation and data logging.

Responsibilities

Lead the hardware integration and validation of complex laser-based wafer manufacturing systems, including optical, mechanical, electrical, and precision motion subsystems.
Develop and execute detailed hardware test procedures – from subsystem acceptance tests to system-level validation – ensuring performance meets design and reliability requirements.
Perform hands-on testing, troubleshooting, and root-cause analysis across electrical, mechanical, optical and controls domains.
Work closely with technicians to ensure consistent build quality, accurate documentation, and reproducible test processes.
Design and specify test setup, instrumentation and data acquisition requirements needed to validate system functionality and performance.
Collect, analyze, and interpret test data, identifying trends, deviations, and opportunities for design or process improvements.
Contribute to the development of automation tools for data collection and test execution (LabVIEW, Python, or equivalent).
Collaborate with cross functional teams – including mechanical, electrical, optical, and software engineers to resolve integration and performance issues.
Contribute to design and readiness reviews, providing feedback focused on hardware testability, manufacturability, and serviceability.
