Senior PLC Engineer - Automation & Commissioning

ABOUT THE ROLE

Own the electrical and software side of automated machinery, from panel build through to production handover. You will be the in office technical point of contact for PLC logic, HMI, robotics and vision integration - writing the control logic, proving it on the machine, and getting the line to run reliably. This is a hands-on site role: expect equal time at the laptop and at the panel.

The position is on Syntek Automation LLP payroll, deployed on-site at client premises in Krishnagiri, Tamil Nadu. You will report to Syntek's Technical Lead through a weekly online review, with day-to-day coordination at the client site.

KEY RESPONSIBILITIES

Control software development

- Develop, structure and document PLC logic (ladder / function block) for machine and line-level control.
- Build HMI screens for operator interfaces - recipes, alarms, diagnostics and production counters.
- Program robots for pick-and-place, material handling and machine-tending applications.
- Configure and integrate vision systems for inspection, presence checks and code reading.
- Set up servo drives, VFDs, motion profiles and sensor calibration.

Electrical commissioning and panel work
- Read and mark up electrical schematics, I/O lists and cable schedules; feed corrections back to design.
- Supervise or execute control panel wiring, terminations and pre-power checks.
- Carry out field installation: sensors, actuators, safety devices, drives and network cabling.
- Perform I/O checkout, dry runs, safety circuit validation and interlock testing before production trials.





Integration and problem solving

- Integrate new equipment into existing lines with minimum production disruption.
- Diagnose and resolve electrical, logic, communication and mechanical-interface faults on live equipment.
- Work with mechanical, quality, production and IT teams to close integration gaps.
- Drive cycle-time, uptime and false-reject improvements once the machine is running.

Documentation and handover

- Maintain versioned backups of all PLC, HMI, robot and vision programs.
- Produce as-built drawings, I/O lists, parameter sheets and commissioning reports.
- Train operators and maintenance staff; hand over troubleshooting guides and spare-part lists.
- Submit weekly progress reports to Syntek's technical lead.

ESSENTIAL SKILLS

- Independent PLC programming and debugging on at least one mainstream platform (Mitsubishi, Siemens, Omron, Allen-Bradley or equivalent), with the ability to pick up a new PLC platform quickly, as the client standard may differ from your current one.
- HMI development on any mainstream platform: screen design, alarm handling, recipe management.
- Industrial communication: Modbus RTU/TCP, EtherNet/IP, EtherCAT, CANopen or Profinet.




- Servo and VFD configuration, tuning and troubleshooting.
- Ability to read and correct control panel drawings, and to wire and test a panel unaided.
- Confident use of a multimeter, oscilloscope and diagnostic software on a live machine.
- Site discipline: safety compliance, LOTO, working at height, shop-floor conduct.

DESIRABLE SKILLS

- Robot programming - SCARA, parallel-kinematic or 6-axis articulated (Epson, Fanuc, Yaskawa, Universal Robots or similar).
- Machine vision setup, including lighting and optics selection.
- AutoCAD Electrical or EPLAN.
- SCADA / MES exposure - OPC UA, SQL logging, dashboard tags, IIoT gateways.
- Safety PLC or safety relay architecture and risk-assessment awareness.
- Experience in electronics, EMS, SMT or precision assembly manufacturing.

WHAT WE LOOK FOR

- Solves problems on the floor rather than escalating them upward.
- Clear communication in English; Tamil and/or Hindi an advantage for shop-floor coordination.
- Willing to work extended hours or shifts during commissioning and production ramp-up.
- Open to short-notice travel for site work and factory acceptance testing.

WHAT WE OFFER

- Direct exposure to a large multinational electronics manufacturing operation.
- Ownership of complete machines rather than a narrow slice of a project.
- Structured technical mentoring from Syntek's engineering leadership.
- Salary commensurate with experience and demonstrated capability.

When applying, include a short note on two machines you have commissioned end to end.
