Senior Field Engineer, Controls

Role Overview

• Integrate Overview.ai systems into automation lines and make them rock-solid.
• Commission and troubleshoot PLC-to-device communication across common industrial protocols:
• EtherNet/IP, PROFINET, Modbus, OPC UA
• Diagnose and eliminate timing and triggering issues:
• double triggers, missed triggers, trigger bounce, incorrect edge detection, latency/jitter, inconsistent handshakes
• Debug inconsistent network communication:
• packet loss, unstable links, IP conflicts, switch configuration issues, grounding/noise coupling, cable quality, EMI, misconfigured QoS/VLANs (where applicable)
• Work with PLC logic and machine sequencing to ensure correct system behavior:
• interpret and modify ladder logic / structured text (as needed) to stabilize integration and performance
• Build repeatable integration standards:
• wiring patterns, sensor conditioning recommendations, network topologies, validated PLC templates, commissioning checklists
• Troubleshoot sensors, discrete I/O, and signal conditioning in real factory environments:
• NPN/PNP sensors, pull-ups/pull-downs, filtering/debounce, shielding/grounding, noise mitigation
• Use multimeters and oscilloscopes to diagnose:
• voltage levels, signal bounce, timing alignment, interference, poor grounding, intermittent connections
• Identify root cause quickly and implement robust fixes—not temporary patches.
• Be the senior technical point of contact on-site: calm, decisive, and structured under pressure.
• Train customer automation engineers and technicians on best practices for operation and first-line troubleshooting.
• Capture high-quality issue reports for HQ engineering:
• reproduction steps, logs, electrical measurements, network symptoms, PLC state, and recommended fixes
• Drive feedback loops that result in real product improvements (tooling, diagnostics, reliability features).

Requirements

• Deep PLC / controls engineering experience (you can independently commission and debug automation lines)
• 5+ years in controls / automation / field engineering in high-volume manufacturing environments
• Hands-on expertise with industrial networks and protocols:
• EtherNet/IP, PROFINET, Modbus, OPC UA (practical troubleshooting, not just theory)
• Strong electrical debugging ability:
• multimeter + oscilloscope competence, reading schematics, signal conditioning, EMI/noise intuition
• Strong understanding of sensors, triggering, and real-time sequencing on production lines
• Mandarin fluency (native or near-native)
• Working English for technical communication with global teams

Benefits

• Extreme growth + real-world impact: We’re not building demos. We’re deploying AI systems on real production lines, at scale.
• Talent density: You’ll work with world-class engineers and operators across AI, embedded systems, and enterprise deployment.
• Front-row seat to the AI manufacturing wave: This is one of the biggest transformations happening in industry right now.
• Ownership: In this role, your work directly changes the trajectory of the company. Great hiring = winning.
• Global exposure: You’ll recruit for roles that touch the most advanced customers and factories in the world.
