PLC programmer / controls engineer / automation engineer — same job, three titles
Here's a small, annoying problem that costs people jobs.
A plant in Alberta needs someone to program PLCs, troubleshoot drives, and keep a line running. They post it as Controls Engineer. A nearly identical plant in Ontario needs almost exactly the same person and posts it as Automation Specialist. A third company calls the same work PLC Programmer, a fourth calls it Electrical Controls Technician, and a fifth — my personal favourite — buries it under Maintenance Electrician and then describes ninety percent programming in the body of the posting.
If you only search one title, you will miss most of the market. Not some of it. Most of it.
Why the titles are all over the place
There's no single gatekeeper for these titles in Canada, and companies name the role for internal reasons that have nothing to do with your search. HR has a pay band tied to the word Engineer. Or the last person in the role was called a Technician, so the posting reuses the old title even though the work has grown. Or the plant manager wrote the posting at his kitchen table and called it what he's always called it.
There's also a real boundary worth knowing: in most provinces, Engineer is a protected title if you're presenting yourself as a professional engineer, and some roles genuinely do require a P.Eng. or an EIT path — design sign-off, certain consulting work, that sort of thing. Other roles use Engineer loosely to mean "the person who figures out the controls," with no licence required or expected. You can't tell which one you're looking at from the title alone. You have to read the requirements.
So read the job, not the label
When a posting opens, skip straight past the title and look for the verbs and the tools. What will you actually do all week?
Programming and modifying PLC and HMI code is a different daily life than designing panels from scratch. Commissioning new equipment at a customer's site is a different life than maintaining one plant you know like your own garage. If a posting lists Studio 5000 or TIA Portal, drives, basic networking, and troubleshooting existing equipment, you know most of what you need to know — whatever the title says on top.
Pay attention to the quiet lines too. On-call rotation. Travel percentage. Shift work. Those three lines will shape your life more than whether the business card says Engineer or Specialist.
A better way to search
Search by task and platform first, title second. PLC, SCADA, controls, automation, your platform of choice, and your city or province — mix them. Set up alerts for more than one title, because the perfect role for you may be filed under the one you never type.
And apply based on the work, not the label. If you can do seventy percent of what's listed and you're honest about the rest, you're in the range a lot of hiring managers actually hire from. They know the title on the posting was partly guesswork. They wrote it.
A word for employers, since you're reading this too
If your posting isn't getting the right people, look at your title before you blame the market. If the job is mostly hands-on programming and troubleshooting in one plant, a title that sounds like a senior design role in an office tower will attract the wrong resumes and scare off the right ones — especially experienced tradespeople who don't call themselves engineers and will scroll right past your ad.
Use the title your best candidate would type into a search bar at 9 p.m. on their phone. Then describe the real work plainly underneath it. That simple change brings in people who actually want the job you've got, not the one the title promised.
Titles in this trade are a rough map, not the territory. The territory is a cabinet, a laptop, a line that's down, and someone who can get it running again. Search for that, hire for that, and the label on top matters a lot less.
