Industrial Automation Technician
Skilled Trades & Technical Careers
An Industrial Automation Technician is the hands-on person who keeps automated machinery running. The work is installing control panels and field wiring, mounting and calibrating sensors, connecting motors and drives, uploading or adjusting PLC programs, and — when a line stops — tracing the fault with a multimeter, the wiring drawings and the fault codes on the HMI screen until the machine runs again. Much of the job is preventive: checking, cleaning, tightening and testing before things fail. In Nigeria technicians in this line work in breweries and bottling plants, flour and feed mills, food and beverage factories, cement plants, plastics and packaging firms, pharmaceutical plants, and for the automation and equipment companies that install and service that machinery for clients. Experienced technicians also work freelance servicing panels, drives and machines for smaller factories. It suits someone practical who is comfortable with tools and electrical safety, reads drawings and manuals patiently, stays calm when a line is down and supervisors are watching, and is willing to work shifts. A technician who adds PLC programming skill can move up to automation officer or engineer over time.

Exam requirements
Career pathway
WAEC/NECO credits including Mathematics, Physics and English
Needed for polytechnic ND admission. Technical college students take the NABTEB trade certificate in electrical installation or instrument mechanics, which is also a valid starting point.
National Diploma (ND) in Electrical/Electronic Engineering Technology, Mechatronics or Instrumentation & Control
2 years
Offered at Nigerian polytechnics and monotechnics. Not the only door in — some technicians start as apprentices or trainees in a factory — but an ND is what most employers advertise for.
Industrial attachment (SIWES) or factory apprenticeship
6 months to 1 year
ND students do SIWES; those without it should look for a trainee or apprentice position in a maintenance department. This is where you first touch real panels, drives and PLCs, and it is the most common route to a first paid job.
PLC, drives and instrumentation training
Short practical courses on Siemens or Allen-Bradley PLCs, variable speed drives and instrumentation are offered by private training centres in Lagos, Port Harcourt and Abuja, and sometimes by employers. This training, more than any certificate, is what separates an automation technician from a general electrician.
HND or part-time B.Eng for progression
2 years (HND)
After ND and a year of industrial experience, an HND raises the ceiling on promotion; some later convert to a degree and pursue COREN registration as an Engineering Technologist or Technician.
Common challenges
Getting the first factory placement
DifficultMaintenance departments are small and take few trainees, and many students finish ND without ever having worked on live industrial equipment.
How to handle: Apply early and widely for SIWES or trainee slots — write to the HR or engineering manager of every factory within reach, not just the big brand names; packaging, plastics, feed mill and bottling companies take more trainees than people expect. While you wait, get real hours with any technician who will have you: generator and AVR repair, industrial electrical installation, refrigeration, borehole pumps. Employers care that you can wire, measure and fault-find safely.
Being seen as 'just an electrician'
ModerateWithout automation-specific skills a technician gets stuck on lamps, sockets and motor starters, with lower pay and no route into control systems.
How to handle: Deliberately build the automation layer on top of your electrical skill: learn to read ladder logic, understand 4-20mA sensor signals, and practise programming on free PLC simulation software or a cheap Arduino at home. Ask the automation staff at your workplace to let you watch commissioning and take notes. Keep a small notebook of every fault you solved and how — it becomes your evidence at interviews.
Electrical and machine safety risks
DifficultThe job involves live panels, 415V three-phase supplies, moving machinery and working at height or in confined spaces. Careless work injures or kills.
How to handle: Learn and insist on lock-out/tag-out: isolate, lock, test dead before you touch. Buy and use your own insulated screwdrivers, gloves and a good multimeter rather than borrowing whatever is around. Never let pressure to restart a line push you into working on live equipment — refusing once is cheaper than a lifetime injury.
ND/HND ceiling in promotion
ModerateMany Nigerian factories reserve senior engineering titles and pay grades for degree holders, so a strong technician can plateau.
How to handle: Use the years while you are earning to close that gap: HND after ND, then part-time or sandwich degree programmes at state universities run in the long vacation. Also build brand-specific expertise (for example being the person who really knows the Siemens drives on site) — scarce skill gets you pay and consulting side work even where titles are blocked.
