Posted February 27, 2026. - Company: Overview Corporation - Location: Nantong, China - Workplace: On-site - Job type: Full-time - Experience: 5+ years - Posted: 2026-02-27 - Apply: https://jobs.ashbyhq.com/overview/6b07bfd6-a179-4c9f-aae8-1f5069f3ac13/application - Source: https://jobmagic.ai/jobs/senior-field-engineer-controls-overview-corporation-wfhds0 ## 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) ## Description **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)** - 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 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.
