What You’ll Actually Be Doing

If you like being in the field, solving real problems, and working on real production equipment—this is that kind of role.

We support customers in the steel fabrication industry , working on CNC machines, lasers, and automation systems that keep shops running.

You’ll be traveling to customer sites across the U.S. installing, troubleshooting, and repairing equipment. Every week is different, and you’ll be the go-to technical expert when something isn’t working.

What the Job Looks Like Day-to-Day

Install and start up CNC machines, lasers, and automation systems at customer sites

Diagnose and fix mechanical, electrical, and control issues

Work with PLCs, servo systems, I/O, and industrial networking

Read schematics and troubleshoot down to root cause

Get machines back up and running as quickly as possible

Train operators and maintenance teams when needed

Document your work and communicate clearly with customers and internal teams

If you’re more senior:

Handle the toughest troubleshooting jobs

Help train and support other engineers

Be the escalation point when things get complicated

Fast-paced environment with changing schedules

Work in real steel fabrication shops (not clean lab environments)

Travel-heavy lifestyle with independence in the field

What You Need to Bring

3–5+ years (Level II) or 8+ years (Senior) of field service or industrial equipment experience

Strong electrical and mechanical troubleshooting skills

Experience with CNC machines, PLCs (Allen Bradley is a plus), and automation systems

Ability to read schematics and work independently in the field

Willingness to travel frequently across the U.S.

Bonus if you have experience with:

Welding equipment or processes

Laser cutting systems

Robotics or automated manufacturing systems

No degree required if you’ve got the hands-on experience.

What Makes This Role Worth It

High travel role – for people who don’t want to sit behind a desk

Hands-on work – real troubleshooting, not just swapping parts

Autonomy – you’re trusted to figure it out and get the job done

Overtime eligible – you get paid for the hours you work
