Senior Field Engineer (Controls)

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.
