Job Description: Senior Field Engineer (Controls) at Overview.ai Location: Shenzhen, China Employment Type: Full time Location Type: Hybrid Department: Overview China About Overview.ai:
- AI computer vision company focused on manufacturing inspection problems unsolvable by traditional machine vision.
- Full-stack company deploying GPU-powered cameras on production lines, running inference on the edge, and operating a platform supporting large fleets globally.
- Known for high accuracy, fast deployment, and operator-friendly experience enabling real factory rollouts.
Why this role is exciting:
- Real production ownership on the factory floor (not just support).
- Solve hard problems like intermittent I/O, timing jitter, noisy signals, flaky networks, multi-trigger edge cases, cycle-time constraints.
- High learning and leverage working with AI, embedded, and firmware teams.
- Work among fast, intense people with direct impact.
- High travel and autonomy as senior technical owner across multiple sites.
Responsibilities (What you’ll own): Controls + line integration (core):
- Integrate Overview.ai systems into automation lines to make them rock-solid.
- Commission and troubleshoot PLC-to-device communication across industrial protocols: EtherNet/IP, PROFINET, Modbus, OPC UA (and variants).
- Diagnose and eliminate timing and triggering issues such as double triggers, missed triggers, trigger bounce, incorrect edge detection, latency/jitter, inconsistent handshakes.
- Debug inconsistent network communication including packet loss, unstable links, IP conflicts, switch config issues, grounding/noise coupling, cable quality, EMI, misconfigured QoS/VLANs.
- Work with PLC logic and machine sequencing to ensure correct system behavior; interpret/modify ladder logic/structured text as needed.
- Build repeatable integration standards: wiring patterns, sensor conditioning recommendations, network topologies, validated PLC templates, commissioning checklists.
Electrical + signal integrity debugging (hands-on):
- Troubleshoot sensors (NPN/PNP), discrete I/O and signal conditioning in real factory environments including 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 causes quickly and implement robust fixes.
Field leadership + customer trust:
- Senior technical point of contact on-site; calm and decisive under pressure.
- Train customer automation engineers/technicians on best practices for operation and troubleshooting.
- Capture high-quality issue reports for HQ engineering including reproduction steps/logs/electrical measurements/network symptoms/PLC state/recommended fixes.
- Drive feedback loops resulting in real product improvements.
Requirements: Required:
- Deep PLC / controls engineering experience; able to independently commission/debug automation lines.
- 5+ years in controls/automation/field engineering in high-volume manufacturing environments.
- Hands-on expertise with industrial networks/protocols: EtherNet/IP, PROFINET, Modbus, OPC UA (practical troubleshooting).
- Strong electrical debugging skills including multimeter + oscilloscope competence; reading schematics; signal conditioning; EMI/noise intuition.
- Strong understanding of sensors/triggers/real-time sequencing on production lines.
- Mandarin fluency (native or near-native).
- Working English for technical communication with global teams.
Traits that matter:
- Move fast but stay methodical (hypothesis → test → isolate → fix → prevent recurrence).
- Highly ownership-driven; downtime is personal.
- Clear communication with operators and engineers.
- Enjoy field work including travel/factories/getting hands dirty.
Why Overview.ai?
- Extreme growth with real-world impact deploying AI systems at scale on production lines.
- Talent density working with world-class engineers/operators across AI/embedded systems/enterprise deployment.
- Front-row seat to AI manufacturing transformation wave.
- Ownership role directly impacting company trajectory.
- Global exposure recruiting for advanced customers/factories worldwide.
