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.
