Hiring Solution
Hire PLC Engineers Who Can Code
We screen PLC engineers against your specific platform, not a generic automation title. Candidates are validated on ladder logic, structured text and HMI integration before submittal.
Business case
Why this hire matters
Platform-specific validation
A Studio 5000 background does not automatically transfer to TIA Portal. We confirm depth on your specific platform before referral so ramp-up time is minimized.
Live code review capability
We ask candidates to review anonymized ladder logic and explain what it does, filtering out engineers who can talk about PLCs but cannot read them.
Retrofit versus greenfield distinction
Modifying live production logic requires different judgment than writing new code from a blank project. We match candidates to the type of work you actually need.
HMI and SCADA integration fluency
We confirm candidates have tied PLC logic to HMI screens and historian tags in practice, not just configured standalone controllers.
Candidate profile
What a strong candidate looks like
These are the markers our recruiters verify before a candidate reaches your shortlist.
- Demonstrated hands-on programming in Studio 5000, TIA Portal, or an equivalent platform matching your environment
- Comfortable reading and modifying existing ladder logic without a rewrite
- Has integrated PLC logic with HMI/SCADA systems including Ignition or FactoryTalk
- Understands I/O wiring, network topology and fieldbus protocols relevant to the plant
- Experience troubleshooting live production line faults under time pressure
- Able to document logic changes and maintain revision control discipline

Screening
How we qualify candidates
Platform match verification
Step 1
We confirm which PLC platforms and firmware versions the candidate has coded on directly.
Logic review exercise
Step 2
Candidates interpret an anonymized logic sample and describe its function and likely failure points.
Troubleshooting interview
Step 3
We walk through a live-fault scenario and evaluate the candidate's diagnostic sequence.
Network and I/O check
Step 4
We confirm familiarity with your fieldbus or Ethernet/IP architecture and I/O module types.
Reference verification
Step 5
Prior managers confirm scope of programming responsibility versus support-only roles.
Timeline
What the hiring timeline looks like
Requirement scoping call
Days 1-2
We capture platform, plant type and whether the role is retrofit or new-build programming.
Shortlist delivery
Days 3-8
A shortlist of platform-matched candidates is typically ready within the first week.
Technical interview
Week 2
Your engineering team runs technical interviews, often including a live logic walkthrough.
Start date coordination
Week 2-3
Selected candidates are onboarded on a schedule that fits your changeover window.

Common hiring mistakes
Assuming platform experience is interchangeable
An engineer strong in one PLC platform can take weeks to become productive in another. Hiring without platform-specific screening slows commissioning of new lines.
Skipping the logic review step
Resume claims of programming experience often overstate depth. Skipping a hands-on review risks placing someone who can configure but not troubleshoot.
Underweighting documentation habits
Engineers who modify live logic without version control leave the next engineer, or the plant, exposed during the next outage.
Ignoring shift and plant culture fit
PLC roles often require working around production schedules. Mismatched availability leads to late-night escalations and turnover.
