## Description (the employer's text)

### About Overview.ai

Overview.ai is bringing the cutting edge of AI computer vision to manufacturing—solving inspection problems that were previously not solvable with traditional machine vision. We’re a full-stack company: we deploy GPU-powered cameras on production lines, run inference on the edge, and operate a platform that supports large fleets of devices deployed across the world.

We’re growing extremely fast. Our customers love the product because it works—high accuracy, fast deployment, and an operator-friendly experience that makes real factory rollouts possible (not just pilots).

### Why this role is exciting

Real production ownership: You’re not “support.” You own uptime and line performance where it matters—on the factory floor.

Hard problems, high signal: Intermittent I/O, timing jitter, noisy signals, flaky networks, multi-trigger edge cases, cycle-time constraints—this is what you’ll solve.

High learning + high leverage: You’ll deepen elite controls skills while working alongside world-class AI, embedded, and firmware teams to ship permanent fixes into the product.

Talent density: You’ll be surrounded by fast, intense people who execute. Your work will be taken seriously and acted on quickly.

High travel, high autonomy: You’ll be trusted as the senior technical owner across multiple sites.

### What you’ll own

### Controls + line integration (core of the job)

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 (and real-world variants)

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

### Electrical + signal integrity debugging (hands-on)

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.

### Field leadership + customer trust

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).

### What we’re looking for

### Required

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

### Traits that matter (we screen hard for these)
