Career After Electrical & Electronics Engineering(EEE), Electronics & Instrumentation Engineering (EIE), Electronics & Communication Engineering (ECE) & Mechanical Engineering: The Power of Automation (PLC, HMI, SCADA, VFD)

The Real Job Question for Engineering Students

Every year, thousands of students graduate in Electrical & Electronics Engineering (EEE) , Electronics & Instrumentation Engineering (EIE) , Electronics & Communication Engineering (ECE) & Mechanical Engineering, but the same question comes up again and again:

“Where are the jobs?”
“Should I go for IT or stay in my core field?”

The truth is, the job market has changed, not disappeared.
Industries still need engineers, but they now want skilled engineers, those who understand automation, control systems, and modern tools like PLC, HMI, SCADA, and VFD.

This blog post lays out the actual job market in straightforward ways. It covers career paths for engineers in India and other countries too. It also points out why picking up automation skills matters so much for students in core engineering fields to get ahead.

The Shift: Why Many Engineers Move to IT

The shift comes down to a few key things. One big factor stands out right away. IT jobs show up more easily during campus recruitment drives.

  • Easier availability of IT jobs through campus placements.

  • Higher entry-level salaries in software companies.

  • Lack of awareness about automation and industrial jobs.

  • Fewer colleges focusing on hands-on technical training.

But what many students don’t realize is that industrial automation is a recession-free, high-growth career, and those with the right technical skills earn equally well or better than IT engineers, especially after a few years of experience

Understanding Automation: The Future of Core Engineering

It shows up all over the place. You see it in factories, airports, power plants, and even smart homes these days. This stuff really forms the backbone of Industry 4.0. In that world, machines get connected, monitored, and controlled through all sorts of intelligent systems.

Every engineer ought to know the four main pillars of modern automation.

Electrical, Instrumentation,Communication & Mechanical Engineers

These four together form the Core of Industrial Automation.

Learning them opens doors in manufacturing, power plants, process industries, oil & gas, pharmaceuticals, food processing, and renewable energy – both in India and abroad.

Job Market Overview (India & Abroad)

India

India keeps turning into this big spot for global manufacturing thanks to pushes like Make in India and Digital India. Companies in automation such as Siemens, ABB, Rockwell, Schneider, Honeywell, Mitsubishi, and Omron are growing their operations there:

  • PLC & SCADA programming

  • Maintenance and commissioning

  • Process control and instrumentation

  • Plant automation and data logging

Salary Range (India):

  • Freshers: ₹3 – 6 L per annum

  • Mid-level engineers: As per experience

  • Senior automation specialists: As per experience.

Automation jobs are practically recession-proof, because every industry depends on automated machines.

Abroad

Automation engineers see strong demand in places like USA, UK, Gulf countries, Europe, Canada, and Australia. That comes from a real shortage of trained technicians out there.

Experienced ones can earn twenty five to seventy lakhs per year. It all depends on the project and where you end up working. Global employers usually look for candidates who know PLC, HMI, SCADA, and Drives. Hands-on project experience makes a big difference too.

 

Why PLC, HMI, SCADA, and VFD Skills Are Game-Changers

People often ask how these skills bring real value to the work. Let us break it down for each one step by step.

1. PLC (Programmable Logic Controller)

  • Functions as the central processing unit of the entire machine operation. 

  • Used to automate repetitive processes such as packaging, bottling, assembly lines, etc. 

  • Must have knowledge of ladder logic programming (Siemens TIA Portal, Allen Bradley, Schneider & Delta etc.)

  • Careers include: PLC Programmer, Control Engineer, Commissioning Engineer

2. HMI (Human Machine Interface)

  • Is the touchscreen or control panel that operators use on a daily basis. 

  • Allows operators to see the entire continuous process and control/set the parameters. 

  • Common tools in this area include WinCC, Wonderware InTouch, and FactoryTalk View.

  • Careers include: HMI Developer, Control Room Engineer. 

3. SCADA (Supervisory Control and Data Acquisition) 

  • Used in large scale industries to allow monitoring of big plants remotely. 

  • Data gathered from sensors is displayed in control rooms. 

  • Common tools include: Wonderware, Citect, iFix, Ignition.

  • Careers include like SCADA Engineer, Process Automation  Specialist.

 4. VFD stands for Variable Frequency Drive. 

  • A motor control system that not only varies and controls the speed of a motor, but reduces power consumption as well.

  • You often find these devices in places like elevators, pumps, fans, and conveyors where precise control matters.

  • For electrical and mechanical engineers, learning to connect and program VFDs turns out to be really essential. It covers a lot of practical needs in the field.

  • Jobs that involve this kind of work include Drive Specialist, Maintenance Engineer, and HVAC Control Engineer.

 

Who Should Learn Automation?

Automation is not only for electrical engineers — it benefits multiple branches:

Branch

Why It’s Important

Job Opportunities

EEE

Direct link to electrical systems, power control, and motor operations.

PLC Programmer, Control Engineer, Maintenance Engineer

EIE

Focuses on sensors, instruments, and process control — fits naturally into automation.

Instrumentation Engineer, SCADA Engineer

ECE

Knowledge of circuits and communication helps in industrial networks, IoT, and control panels.

Automation Engineer, Control Engineer, Industry 4.0

Mechanical

Machines, motors, and production lines all run through PLCs & Drives.

Mechatronics Engineer, Maintenance Engineer, HVAC Automation Engineer

This means automation training creates a bridge between mechanical systems and electrical control — the foundation of modern industry.

 

How to Build a Career in Industrial Automation

How to Build a Career in Industrial Automation

Here is a stepwise plan:

Step 1: Learn the Basics

Understand sensors, motors, relays, switch, and electrical wiring. All automation is based on these.

Step 2: Get Hands On with PLCs & Drives

Take practical training that allows you to connect, program, and troubleshoot actual PLCs (Siemens, Schneider, Allen Bradley, Delta, Mitsubishi). Do not just focus on theory – hands-on experience is what matters the most.

Step 3: Learn PLC, SCADA & HMI

Learn to design an interface to visualize live data from machines. Create small projects such as controlling a motor or the movement of a conveyor belt using SCADA.

Step 4: Understand VFDs & Panel Wiring

Learn how to control the speed, torque, and direction of motors. Combine your VFD with a PLC program, and you’ll have complete automation.

Step 5: Work on Real Projects & Internships

Every industry values practical exposure. Join internships or contribute to small industrial projects in automation, water plants, or manufacturing units.

 

Step 6: Build a Resume & Portfolio

Make sure to add your project experience, examples of PLC programming and even certificates in automation to your resume. Also make sure to mention the tools used (TIA Portal, Wonderware, iFix, etc).

Step 7: Apply for the Job

  • When searching for jobs, look for positions such as:

  • PLC Programmer / Automation Engineer,

  • Control Systems Engineer,

  • Maintenance Engineer,

  • Instrumentation Engineer,

  • Process Automation Specialist,

  • Drive Commissioning Engineer.

  • Here’s a step-by-step roadmap:

Automation engineers are required in Power plants, Cement plants, Steel plants, Sugar plants, oil & gas, food processing, pharmaceuticals, packaging, automobile, and building automation sectors.

How Automation Helps EEE, EIE, ECE & Mechanical Students Stand Out
