Automation Engineer

About AtmosPower Pvt. Ltd.

AtmosPower Pvt. Ltd. is an Ahmedabad-based full turnkey EPC company specialising in PSA/VPSA-based industrial gas plants (biogas upgradation, oxygen and nitrogen) and Compressed Biogas (CBG) plants, with 150+ plants commissioned across India in the 1006,500 m/hr range.

Role Overview

We are looking for an experienced Instrumentation professional to own the complete instrumentation scope of our projects, from engineering and procurement support through inspection, commissioning and after-sales troubleshooting.

Key Responsibilities

• Develop and maintain Siemens PLC programs (S7-1200 / S7-1500, TIA Portal) for plant sequences, valve-switching cycles, PID loops, alarms and interlocks, based on the approved control philosophy and cause-and-effect matrix.
• Configure HMI/SCADA screens (Siemens WinCC or equivalent): mimics, alarms, trends, data logging and reports.
• Prepare the PLC hardware configuration and I/O mapping from the project I/O list; maintain program documentation, version history and backups for every plant.
• Set up communication between the PLC and third-party equipment such as VFDs, gas analysers, compressors and packaged skids over Profinet and Modbus RTU/TCP.
• Test PLC and HMI logic by simulation and during control panel FAT (Factory Acceptance Testing); support the instrumentation team in I/O checks, loop checks and SAT (Site Acceptance Testing) at site.
• Commission control systems at site and tune sequences and control loops during start-up with the process team.
• Provide remote and on-site troubleshooting for running plants, including fault diagnosis and program changes.
• Support the instrumentation team on field instrument configuration and control panel drawing review.

Required Qualifications & Skills

• Education: B.E. / B.Tech in Instrumentation & Control, Electronics & Instrumentation, Electrical or Electronics.
• Experience: Minimum 23 years of hands-on Siemens PLC programming.
• Proficient in TIA Portal / STEP 7 using Ladder (LAD), Function Block Diagram (FBD) and Structured Control Language (SCL); able to write a program from a control philosophy, not only modify existing code.
• Experience in HMI/SCADA development; Siemens WinCC preferred.
• Working knowledge of Profinet, Profibus, Modbus, 420 mA / HART signals, PID loops and VFD integration.
• Able to read P&IDs, loop diagrams and panel wiring drawings; has commissioned at least one PLC system at site.

Preferred Experience

• Background from industrial automation companies or system integrators, or from process-plant OEMs and EPCs in oil & gas, chemicals, water & wastewater, power or industrial gases.
• Experience with sequence-based logic (valve-switching or batch cycles) and plants handling flammable gases.
• Exposure to other PLC platforms (Allen-Bradley, Schneider, Mitsubishi, Delta) and AutoCAD.
