Position Summary

The Senior Electrical Engineer - Triggering & PCBA Design will lead the design, development, and validation of high-precision triggering electronics and printed circuit board assemblies (PCBAs) that serve as core components for Onto Innovation's capital equipment platforms. This engineer will design low-latency, deterministic trigger architectures; integrate precision timing circuits; and develop robust PCBAs that ensure accurate system synchronization, motion coordination, sensor acquisition, and metrology performance.

This is a senior technical role requiring strong electrical design depth, systems integration experience, and the ability to collaborate across multiple engineering functions to drive foundational platform capability.

Key Responsibilities

Triggering Architecture Design

• Design and implement high-precision, low-latency electrical triggering circuits used across Onto platforms.
• Develop deterministic timing architectures for synchronization of optics, motion, sensing, image acquisition, and metrology subsystems.
• Define trigger interfaces, electrical standards, and timing specifications for cross-product reuse.

PCBA Design & Development

• Lead schematic design, PCB layout reviews, component selection, and design validation for trigger-related and general-purpose platform PCBAs.
• Ensure compliance with electrical performance requirements, EMI/EMC robustness, thermal constraints, and reliability specifications.
• Collaborate with supply chain and manufacturing to ensure strong DFM/DFT outcomes and reliable build quality.

System Integration & Validation

• Work with systems engineering to integrate trigger electronics into platform modules and system-level architectures.
• Perform circuit bring-up, debug, functional testing, and characterization of timing performance.
• Lead root-cause investigations for electrical timing, jitter, sync instability, or triggering failures across product lines.

Standards, Documentation & Continuous Improvement

• Develop and maintain electrical triggering standards, best practices, and platform documentation.
• Establish common trigger hardware and interface architectures that simplify adoption across product groups.
• Identify and drive improvements in electrical timing accuracy, jitter performance, and system synchronization reliability.
