For Synergie Controls, I would make this role more project-oriented, because the PLC Programmer should not only write PLC logic but also handle panel testing, HMI integration, commissioning and customer-site troubleshooting. Siemens’ current STEP 7/TIA Portal workplace supports S7-1200/1500 programming, distributed I/O, motion and safety, so these should be reflected in the JD. (Siemens Totally Integrated Automation)

12. Work Location

Synergie Controls & Systems Pvt. Ltd. Taloja, Navi Mumbai, Maharashtra

Working requirement: Primarily Taloja office/workshop with customer-site travel as required for FAT, commissioning and troubleshooting.

My recommendation: For Synergie, I would keep 2–6 years experience as the main hiring range and conduct a practical test before selection—for example, give the candidate an S7-1500 + ET200SP I/O + motor start/stop + interlock + analog signal + HMI screen task. This will quickly show whether the candidate is actually a PLC programmer or only has theoretical TIA Portal knowledge.
