Estimates for a small start in Canada, not guarantees.

What it is

You write and troubleshoot control programs (PLCs, operator screens, simple robot cells) for manufacturers and for larger integrators who need extra hands. Most design work is done on a laptop, with trips to site to commission and support.

Your first three steps

  1. Pick one or two platforms you know well (for example Allen-Bradley or Siemens) and set up a licensed laptop with the software
  2. Tell former employers, local integrators and machine builders that you are taking on contract work, and ask what overflow they have
  3. Get quotes for professional liability (errors and omissions) and commercial general liability insurance, and write a simple contract with a clear scope
Who pays

Small and mid-sized manufacturers, food and packaging plants, machine builders and larger integrators that subcontract.

How it makes money

Hourly or day rate for programming and support, fixed quotes for small upgrades, and paid support or call-out agreements after a job is finished.

Skills that help
  • PLC programming and industrial controls knowledge
  • Reading electrical drawings
  • Clear communication with plant staff
  • Careful documentation and testing
Watch out for
  • Engineering rules: check your provincial engineering regulator on whether your work needs a P.Eng. or sign-off, and avoid using protected titles such as 'engineer' unless licensed
  • Electrical wiring and panel work usually needs licensed electricians or certified panel shops, check provincial rules
  • Machine safety standards (such as CSA Z432 and Z434 for robots), you are responsible for safe designs
  • Professional liability and commercial general liability insurance, since a faulty program can stop a production line
  • Software licences can be costly, check licence terms for contractors
  • Site safety training and PPE requirements at plants, and registration with WCB/WSIB if you hire help
