Job description
### **About** [****](http://Overview.ai)
[](http://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 [](http://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)**
● You move fast and stay methodical: hypothesis → test → isolate → fix → prevent recurrence
● You’re highly ownership-driven: downtime is personal
● You communicate clearly with both operators and engineers
● You enjoy the field: travel, factories, and getting your hands dirty
**Why** [****](http://Overview.ai) **(why top candidates join)**
● **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.
