Finding the right automation contractor can make the difference between a project that finishes on time and under budget—and one that drags on for months with cost overruns and technical issues.
But if you've never hired an automation contractor before, the process can be overwhelming. Where do you find qualified candidates? How do you evaluate their technical skills? What should you pay? What contract terms are standard?
This comprehensive guide answers all these questions and more. Whether you're hiring your first PLC programmer or building a roster of go-to contractors for ongoing projects, you'll learn exactly how to find, vet, negotiate with, and manage automation contractors effectively.
Why Hire Automation Contractors?
Before we dive into the "how," let's quickly cover the "why." Automation contractors offer several advantages over full-time hires:
Cost Efficiency
- No benefits overhead: Save 30-40% on benefits, insurance, 401k contributions
- Pay only for work delivered: No downtime between projects
- No training costs: Contractors bring expertise from Day 1
Flexibility
- Scale up/down quickly: Hire for a 3-month project, then scale back
- Access specialized skills: Need a FANUC robot expert for 6 weeks? Hire one.
- No long-term commitment: Perfect for project-based work
Speed
- Faster hiring: Contractors can start in days, not months
- Immediate productivity: No 3-6 month ramp-up period
- Proven track record: You can see their portfolio before hiring
Expertise
- Cross-industry experience: Contractors have seen dozens of plants and systems
- Latest technology: They stay current to remain competitive
- Problem-solving: They've solved problems you haven't encountered yet
When to hire a contractor:
- ✅ One-time projects (upgrades, installations, migrations)
- ✅ Specialized skills your team doesn't have
- ✅ Peak workload periods
- ✅ Emergency troubleshooting
- ✅ Temporary backfill for staff on leave
When to hire full-time:
- ✅ Ongoing maintenance and support
- ✅ Long-term capacity building
- ✅ Core competencies you want in-house
Where to Find Automation Contractors
Let's start with the most important question: Where do you actually find qualified automation contractors?
1. AutomateAmerica FEED (Recommended)
What it is: A specialized platform connecting employers with vetted automation contractors across North America.
Why we recommend it:
- ✅ Pre-screened contractors: All profiles verified with work history, skills, certifications

- Robotics integration specialists (FANUC, ABB, KUKA)
- Controls engineers (full-stack automation projects)
How to use:
- Post your contract with detailed requirements
- Browse contractor profiles and invite candidates
- Review applications and portfolios
- Interview top candidates
- Hire and manage through the platform
2. General Freelance Platforms
Upwork, Toptal, Freelancer:
Pros:
- Large pool of contractors
- Established payment and dispute resolution
- Global talent access
Cons:
- ❌ Not specialized in automation (mostly software developers)
- ❌ Harder to vet technical skills
- ❌ Platform fees can be 15-20%
- ❌ Few contractors with industrial automation experience
Verdict: Use for general engineering tasks, but not ideal for specialized PLC/SCADA/robotics work.
3. LinkedIn

Writing an Effective Contract Posting
Once you know where to search, you need to write a posting that attracts qualified contractors and filters out unqualified ones.
Essential Elements of a Contract Posting
1. Project Title (Be Specific)
❌ Bad: "Need PLC Programmer" ✅ Good: "Allen Bradley ControlLogix Programmer for Automotive Assembly Line Upgrade"
Why: Specific titles attract relevant contractors and filter out those without the right skills.
2. Project Overview (2-3 paragraphs)
Describe:
- What you're building/upgrading/fixing
- Current state vs desired state
- Business impact (why this matters)
Example: "We're upgrading an automotive door panel assembly line from legacy PLC-5 controllers to ControlLogix. The line currently produces 180 units/hour but experiences frequent downtime (78% uptime). The goal is to improve reliability to 95%+ uptime and increase throughput to 240 units/hour. This is a critical line for our plant, and we have a 10-week shutdown window starting March 1st, 2026."
3. Scope of Work (Bulleted List)
Be as specific as possible:
Example:
- Convert 6 existing PLC-5 programs to ControlLogix (Studio 5000 v33)
- Integrate 8 FANUC R-2000iB spot welding robots
- Develop FactoryTalk View SE HMI with production tracking
- Commission system during 2-week plant shutdown
- Train 2 maintenance technicians on new system
- Provide as-built documentation and commented code
4. Required Skills (Be Realistic)
Must-have skills:
- Allen Bradley ControlLogix programming (Studio 5000)
- FANUC robot integration
- FactoryTalk View SE development
- Automotive manufacturing experience
Nice-to-have skills:
- Motion control (Kinetix servo systems)
- Safety systems (GuardLogix)
- German or Spanish language skills
Don't list 20 requirements if only 5 are truly necessary. You'll scare off qualified candidates who have 80% of what you need but not 100%.
5. Duration and Schedule
- Project duration: 10 weeks (March 1 - May 10, 2026)
- Work schedule: 40 hours/week, on-site Monday-Friday
- Shutdown dates: April 5-19 (critical commissioning window)
Be clear about:
- On-site vs remote work
- Expected hours per week
- Flexibility (or lack thereof) on schedule
6. Location and Travel Requirements
- Location: Detroit, MI (on-site required)
- Travel: Local candidates preferred; will consider travel candidates with housing allowance
- Parking: Free parking on-site
7. Budget and Rate
You have three options:
Option A: Post your budget "Budget: $95-120/hour depending on experience"
Pros: Filters out contractors outside your range Cons: May anchor negotiations at the high end
Option B: Ask for proposals "Please provide your hourly rate in your application"
Pros: Allows you to see market rates Cons: More applications to sort through
Option C: Don't mention budget "Competitive hourly rate based on experience"
Pros: Maximizes applicant pool Cons: Wastes time if your budget doesn't match market rates
Recommendation: Post your budget range. It saves everyone time.
8. Application Requirements
Tell contractors exactly what to submit:
- Resume/CV with relevant project experience
- Portfolio examples (at least 2 similar projects)
- Hourly rate and availability
- References from past clients (at least 2)
- Cover letter explaining why you're a good fit
Pro tip: Require a specific keyword in the application (e.g., "In your cover letter, start with 'Detroit Assembly Line Upgrade'"). This filters out mass-application spam.
