Job Description

Senior Field Engineer (Controls) ABOUT OVERVIEW.AI http://Overview.ai 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 Overview.ai 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, E ...
