Commissioning Engineer job description, written by automation engineers
A copy-ready commissioning engineer job description for India, with the duties, qualifications and site conditions, the screening questions that separate hands-on engineers from keyword CVs, and the mistakes that fill your inbox with the wrong people. A commissioning engineer takes a control system from the factory test to a running plant: proves every I/O point and loop on site, runs FAT and SAT, makes the logic and HMI changes the site forces, clears the punch list and hands over the documents. This template is for PLC, SCADA and DCS commissioning in India — site work, not desk programming.

Job title
Commissioning Engineer — [platform family] · [city / site]
About the role
We are hiring a Commissioning Engineer to take [machine / line / process unit] from FAT to a running plant at [site, city]. You will own I/O checkout, loop checks, SAT and start-up on [Siemens TIA Portal / Rockwell Studio 5000 / ABB 800xA / Siemens PCS 7 — name one family], working with the client, the EPC and the instrument team until handover. Expect [x] weeks on site per project and about [x]% travel.
What you will do
- Check panel wiring against the drawings and the I/O list; carry out I/O checkout and loop checks with the instrument technician, and sign the loop folders
- Run FAT against the functional design specification with the customer, then SAT and start-up on site with live field devices
- Make the logic, sequence, interlock and HMI changes the site needs — under change control, with versions, backups and a record of what changed and why
- Fault-find on live systems: field wiring, instrument signals, networks and drives as well as the program
- Own the automation punch list through dry runs, wet runs and start-up until each item is retested and signed off by the client and the EPC
- Work inside the site's permit-to-work and safety system; attend toolbox talks; stop when the permit does not cover the job
- Hand over as-built drawings, the final program backup, alarm and tag lists, test records and operator training
What you must have
- [2–6] years commissioning [the named platform family] on site — name the plants, your scope and what you personally closed out
- At least one project taken from FAT through SAT to start-up and handover
- Hands-on loop checking and I/O checkout; reading P&IDs, loop diagrams and panel schematics
- Industrial networks on real sites — PROFINET or EtherNet/IP, Modbus RTU/TCP — and the fault-finding that goes with them
- Willing and able to travel and stay on site for the window stated above
- B.E./B.Tech or Diploma in Electrical, Electronics, Instrumentation or Mechatronics
Good to have
- A second platform family (one more, not five more)
- Process units: cause-and-effect verification and start-up sequences; DCS or SIS exposure, stated separately
- Drives on site: VFD parameterisation and motor checks
- Hazardous-area practice (IEC 60079); confined-space and work-at-height training
Qualifications
- Degree or diploma in Electrical, Electronics, Instrumentation or Mechatronics engineering
- Hands on the platform family named above. A vendor course certificate shows attendance; the proof is a plant where you used it and what broke
- Site-safety inductions current: permit-to-work, and confined space or work at height where the site needs them
- A valid passport if projects run outside India (Gulf, South-East Asia) — state it only if it applies
Site and travel conditions
- Travel: about [x]% of working time; typical stay [x] weeks per site; sites in [regions / abroad]
- Pattern on site: six-day weeks and shutdown or start-up hours are normal on commissioning — say so here, not at offer stage
- Accommodation, local travel and site allowance: [state what the company provides]
- Safety: PPE provided; the site's induction and permit-to-work rules apply from day one
Questions that separate real experience from a listed skill
What did you do at SAT that you could not do at FAT?
Real commissioners talk about live field devices, loop checks with the instrument technician, the customer’s operators and the changes the site forced. Listed-only candidates repeat the definition.
Tell me about a fault on site that took more than a day to find. What fixed it in the end?
Real answers land in the physical layer — a shield not bonded, a connector, a cable run beside a VFD, a loose module seat — and say what was ruled out first. Pretenders stay in software: “we reloaded the program”.
Who signed your loop folders and punch list, and what was still open at handover?
A real commissioner names the client’s or EPC’s person and the items carried over, with dates. “Everything was closed”, with no names, is a listed-only answer.
These are the lines our engineers listen for when we screen for client mandates. See how TVP screens a candidate end to end.
Three mistakes that attract the wrong CVs
- Hiding the travel and the stay. Commissioning hires fail at offer stage when the site weeks surface late. Put the percentage and the working pattern in the JD.
- Asking for a programmer and expecting a commissioner. Desk programming and site commissioning are different days’ work. Say which you need — or ask for both and screen for both.
- Treating a vendor certificate as site experience. A course proves attendance. Ask for the plant, the scope and what went wrong.

Commissioning Engineer — questions answered
What does a commissioning engineer do?
A commissioning engineer takes a PLC, SCADA or DCS system from the factory acceptance test to a running plant: I/O checkout and loop checks on site, the site acceptance test and start-up, the logic and HMI changes the plant forces, the punch list until it is signed off, and the handover documents — as-builts, backups, alarm and tag lists, test records.
What qualifications does a commissioning engineer need?
A degree or diploma in Electrical, Electronics, Instrumentation or Mechatronics; hands-on time on one PLC, SCADA or DCS family; and site experience — loop checking, FAT and SAT, start-up on a plant you can name. Vendor courses help you get the interview; the plant you commissioned gets you the job. Site-safety inductions (permit-to-work, confined space, work at height) are usually required before you step on site.
How much travel does a commissioning engineer role involve?
Most of the work is on site, usually weeks at a time per project, with six-day weeks and shutdown or start-up hours. How much of the year that is depends on the employer: a system integrator’s commissioning engineer may spend most of it on site; a plant’s own engineer far less. A good job description states the percentage, the typical stay per site and what the company provides for accommodation and local travel.
