Is PLC Programming in Demand? Jobs, Salary & Career Scope

Is PLC programming in demand? The short answer

Yes, PLC programming is in high demand, and the demand keeps growing. Every automated factory, water plant, packaging line and pharma unit runs on PLCs, and there are not enough skilled people to program, commission and maintain them.

At The Core Systems, we deliver PLC automation projects for industry and train engineers through our advanced PLC course. What follows is what we see on the shop floor every week, backed by current market data.

What is PLC programming?

PLC programming is writing the logic that tells a Programmable Logic Controller how to run a machine or process. A PLC reads inputs (sensors, switches, push buttons), runs your program, and drives outputs (motors, valves, conveyors, alarms) in milliseconds, around the clock.

PLC programmers work in the five IEC 61131-3 languages:

Ladder Diagram (LD) – the most common, built to look like electrical relay logic
Function Block Diagram (FBD) – blocks wired together, popular in process control
Structured Text (ST) – a text language similar to Pascal, used for complex maths and data handling
Sequential Function Chart (SFC) – step-by-step sequences for batch processes
Instruction List (IL) – a low-level language, now rarely used

The job rarely stops at the PLC. Most roles also include HMI screens, SCADA systems, VFDs, sensors, industrial networks and on-site commissioning. That broad skill set is exactly why trained PLC engineers are hard to find.

Why PLC programming is in demand: 4 reasons

1. The PLC market keeps growing

Forecasts differ by research firm, but all point up. Global Market Insights projects the global PLC market to nearly triple over a decade, growing about 11.4% a year (GMI). Fortune Business Insights is more conservative at about 6.2% a year, and notes Asia Pacific holds the largest share of the market, close to 40% (Fortune Business Insights). More PLCs installed means more people needed to program and service them.

2. Industry 4.0 and smart factories

Smart manufacturing connects PLCs to SCADA, MES, cloud dashboards and IIoT devices. Companies now want engineers who can program a PLC and get its data onto a network. That raises both the demand and the pay for well-trained people.

3. A real skills gap

Deloitte and The Manufacturing Institute estimate US manufacturing alone could need 3.8 million new workers within a decade, and up to 1.9 million of those jobs could go unfilled if the skills gap is not closed (Automation.com). A later Deloitte analysis expects manufacturing technician jobs to grow six times faster than production jobs (MMH). The same pattern shows up in India: plenty of applicants, too few with hands-on automation skills.

4. Every legacy plant needs upgrades

Thousands of plants still run on old relay panels or obsolete PLCs. Migrating them to modern controllers, adding HMIs and connecting them to SCADA is steady, well-paid project work for automation engineers and system integrators like us.

PLC programming demand in India

India is one of the fastest-growing markets for automation skills. Ken Research estimates the Indian industrial automation market is growing about 8.4% a year (Ken Research). IMARC expects the India machine automation controller market to roughly double over the next decade, growing about 8% a year (IMARC).

Growth in domestic manufacturing, the PLI schemes and new plants in electronics, EV, pharma and food processing all add PLC-controlled lines that need engineers.

Industries hiring PLC programmers in India and abroad:

Automotive and auto components
Food, beverage and packaging
Pharmaceuticals and FMCG
Textiles, paper and steel
Oil and gas, chemicals and petrochemicals
Power, renewable energy and utilities
Water and wastewater treatment
Cement, mining and material handling
Warehousing, logistics and airport baggage systems
Machine builders (OEMs) and system integrators

PLC skills also travel well. Indian automation engineers with Siemens, Allen-Bradley or Mitsubishi experience regularly find commissioning and maintenance roles in the Gulf, Europe and Southeast Asia.

PLC programmer salary in India and top job roles

PLC pay in India starts modest and rises fast with experience. Flexiple’s salary data on more than 4,000 Indian PLC programmers shows median pay growing about 4.2 times over a career, from ₹4.7 lakh a year at 0–2 years to ₹19.6 lakh at 12+ years, with Pune holding the largest talent pool (Flexiple). Indeed job postings put entry-level PLC programmer pay between roughly ₹16,600 and ₹49,700 a month, with Bengaluru and Pune paying the most (Indeed).

PLC programmer / trainee automation engineer (0–2 years): ₹2.5–5 lakh per year
Applications engineer (PLC/automation) (2–5 years): around ₹5 lakh per year median (PayScale)
Automation / controls engineer (PLC + SCADA + HMI) (3–7 years): ₹5–10 lakh per year
Electrical engineer with strong PLC skills (7+ years): around ₹7.9 lakh per year median, with the top 10% near ₹20 lakh (PayScale)
Senior automation lead / commissioning specialist (10+ years): ₹15–20 lakh+ per year
Overseas commissioning engineer (Gulf, Europe) (5+ years): often several times Indian pay

Ranges are indicative and vary by city, company, brand experience (Siemens, Allen-Bradley, etc.) and whether the role includes site travel.

The biggest pay jumps come from three things: hands-on project experience, knowing more than one PLC brand, and adding SCADA, drives and industrial networking to your PLC skills.

Skills employers want from PLC programmers

When we hire for our own projects, and when companies ask us for trained candidates, these are the skills that matter:

PLC programming on major brands – Siemens (TIA Portal, S7-1200/1500), Allen-Bradley (Studio 5000, RSLogix), Mitsubishi, Delta, Schneider, Omron
Ladder logic plus Structured Text – ST is increasingly expected for complex logic and data handling
HMI design – building operator screens with alarms, trends and recipes
SCADA systems – WinCC, FactoryTalk, Wonderware/AVEVA, Ignition
VFDs and servo drives – parameter setting, speed control and motion basics
Industrial communication – Modbus, Profinet, Profibus, EtherNet/IP, OPC UA
Electrical fundamentals – reading wiring and control panel drawings, sensors, field instruments
Troubleshooting and commissioning – finding faults fast on a live machine
IIoT and data skills – sending PLC data to dashboards, MQTT, basic SQL
Safety – interlocks, emergency stops and safety PLC basics

Theory alone does not get you hired. Employers want people who have worked on real PLCs, written real programs and fixed real faults.

Will AI replace PLC programmers? The future of PLC programming

No. AI will change how PLC programmers work, but it will not replace them. Deloitte’s manufacturing outlook still expects people to perform 81% of task hours in the sector, even as automation spending rises (MAU).

Here is why the role is safe:

Physical work stays physical. Someone has to wire panels, test I/O, commission machines and fix faults on site.
Safety needs human sign-off. A wrong output can injure a person or wreck a machine. Plants will not trust unchecked AI code on live equipment.
Every plant is different. Process knowledge, customer requirements and old equipment quirks are hard to automate.

What will change: AI tools will help write boilerplate code, document programs and suggest fixes. Engineers who use these tools well, and who add IIoT, data and networking skills, will earn the most. The future of PLC programming belongs to engineers who keep learning.
