Senior Automation Engineer PLC & Electrical Control Systems

Company: Nimble Vision Technologies Pvt. Ltd. Location: Bengaluru (HQ) — with site travel across Karnataka, Andhra Pradesh, Odisha and NCR Experience: 3+ years Employment type: Full-time Reports to: Head of Engineering / Founders

About the role

We build AI-IoT systems for water infrastructure — borewell automation, STP/WTP control, industrial instrumentation and construction technology. Our systems run live at BWSSB (500+ borewells, 25 GLRs, 110 tankers), Ford India, Ashoka Buildcon and multiple state government deployments.

We are looking for an engineer who can own the electrical and automation side end-to-end: design the control philosophy, program the PLC, get the panel built and procured, define the process so it repeats reliably, and lead a small team executing it at site. This is a hands-on role with ownership, not a supervisory-only position.

Key responsibilitiesPLC, SCADA & control systems

• Design, program, simulate and commission PLC logic (ladder / FBD / SFC) for pumping stations, STPs, dosing systems and industrial process skids
• Develop HMI and SCADA screens, alarm hierarchies, trending and operator interlocks
• Configure and troubleshoot industrial communication — Modbus RTU/TCP, Profibus/Profinet, OPC-UA, and MQTT bridges to our cloud platform
• Implement closed-loop control (PID for level, flow, pressure, DO, dosing) and tune loops at site
• Integrate our NV-series IoT controllers and third-party instrumentation (flow meters, level sensors, multi-parameter analysers, energy meters)

3-phase motor & panel engineering

• Design LT control panels — MCC, PCC, APFC, feeder pillars — including single-line diagrams, schematics, GA drawings and cable schedules
• Select and size motor starting schemes: DOL, star-delta, soft starter, VFD (Danfoss, ABB, Schneider, Delta or equivalent)
• Size cables, breakers, contactors, overload and motor protection relays; specify earthing and surge protection
• Own protection and safety logic — dry run, phase failure, single phasing, over/under voltage, thermal overload, no-flow cutoff
• Commission submersible pumps, blowers, aerators, agitators, screw pumps; carry out load testing, insulation testing and energy verification
• Ensure compliance with IEC 61439, IS 732, CEA regulations and relevant CPCB/OCEMS requirements

Process definition & documentation

• Write control philosophy documents, I/O lists, cause-and-effect matrices and sequence-of-operation documents before execution begins
• Create and maintain standard templates: panel BOM formats, wiring standards, tag naming conventions, firmware/program version control
• Define and enforce FAT and SAT protocols, pre-dispatch checklists, commissioning checklists and handover documents
• Build O&M manuals and train client operators and site technicians
• Drive root-cause analysis on field failures and convert findings into permanent design or SOP changes

Procurement & vendor management

• Prepare accurate BOMs and issue RFQs; run technical and commercial comparisons across vendors
• Negotiate pricing and delivery with OEMs, panel fabricators and distributors; develop alternate sources to de-risk supply
• Manage procurement through GeM and government e-procurement portals where applicable
• Track order-to-delivery timelines against project schedules and escalate slippage early
• Run incoming material inspection, calibration records, warranty claims and spares/inventory planning

Project & team management

• Plan and track multiple concurrent site deployments — resources, schedule, material readiness, manpower
• Lead and mentor a team of junior engineers and site technicians; review their drawings, code and site work
• Serve as the technical point of contact for clients, consultants and government engineers during design reviews and inspections
• Own project cost against estimate and flag variances

Must-have requirements

• Diploma / B.E. / B.Tech in Electrical, Electronics, Instrumentation or Mechatronics
• 4+ years of hands-on experience in industrial automation, water/wastewater treatment, or process plant electrical work
• Independent programming experience on at least one major PLC platform — Siemens (TIA Portal), Allen-Bradley, Schneider, Delta or Mitsubishi
• Strong practical command of 3-phase power systems, motor control and VFD parameterisation
• Ability to read and produce electrical schematics (AutoCAD Electrical, EPLAN or equivalent)
• Proven site commissioning experience — not just design-desk experience
• Willingness to travel to project sites (typically 30–40% of the time)
• Working proficiency in English and Hindi or Kannada

Good to have

• Exposure to STP/WTP unit processes — SBR, MBBR, MBR, aeration, sludge handling, chlorination
• Experience with CPCB online monitoring compliance and pollution control board interfacing
• Familiarity with IoT/edge devices, MQTT, and cloud dashboards
• Basic scripting (Python) for data handling or test automation
• Experience preparing technical submittals for government tenders
• Prior ownership of vendor development and cost reduction initiatives

What we offer

• Direct ownership of systems deployed at state-level water infrastructure scale
• Flat structure with direct access to founders and fast decision-making
• Exposure across the full stack — hardware, firmware, control, cloud, and client-facing delivery
• Competitive compensation with performance-linked components

While applying

Please include, in a short note:

1. One project where you owned the PLC program end-to-end — plant type, PLC make, I/O count, and your specific contribution
2. The largest motor rating you have commissioned and the starting method used
3. Your current location, notice period and expected CTC
