Work Type: Full Time, On Site
Compensation: $115K+ DOE
Why This Role If you'd rather write a PLC program from a blank project than patch someone else's code, this is your seat. Every machine here is one of a kind, so you'll own the controls from first rung to final commissioning. You'll join a growing electrical engineering team at a company that is investing seriously in controls technology.
The Company Our client is a vertically integrated designer and manufacturer of large scale, custom industrial equipment for the heavy manufacturing industry, serving customers across North America. With roughly 185 to 200 employees and $60M+ in annual revenue, they handle every stage in house, including mechanical and electrical engineering, PLC programming, machining, welding, and assembly. They are also building a proprietary controls and automation software platform as part of a broader move toward becoming a technology driven manufacturer. They are investing heavily in their electrical engineering team to keep pace with strong, sustained growth.
The Opportunity Every project is custom; there is no off the shelf system to plug in and go. As Senior Controls Engineer, you'll write PLC programs from scratch for large, one of a kind machines, then see them through testing and on site commissioning. It's a chance to be the go to controls expert on projects that genuinely challenge you, inside a company that is actively investing in this team.
What You'll Do Program and debug PLC logic (ladder logic and structured text)



on Allen-Bradley platforms for custom equipment builds
Write structured, well documented, reusable code, largely from scratch given the custom nature of each project
Configure and start up motion control systems, including servo drives and VFD motors
Test and commission machines prior to shipment, and troubleshoot electrical and mechanical issues during testing and installation
Travel for on site commissioning and customer training, typically 1 to 2 week trips within the U.S. or Mexico
Maintain accurate testing records, specifications, and design documentation
Act as a liaison between mechanical engineering, testing, and the electrical design team to resolve design and manufacturing issues
Share knowledge and provide informal mentorship to less experienced engineers
What You'll Bring Robust, hands on PLC programming experience; Allen-Bradley platforms (RSLogix 5000/500) and HMI programming preferred
Proven ability to write controls code from scratch for custom equipment, not just modify or maintain existing programs
Experience with motion control systems: servo drives, VFD motors, and device networking
Ability to read and interpret electrical schematics; comfortable using AutoCAD Electrical to update drawings
Confident troubleshooting hands on in a shop environment (multimeter, oscilloscope)
Engineering degree, technical diploma, or equivalent hands on experience in electrical and controls
