This is a full-time, onsite role based at our headquarters in Denver, CO.

As a Control Systems Engineer – Manufacturing & Automation, you will apply your expertise in industrial automation and PLC-based control systems to design, stand up, and support advanced manufacturing and assembly lines. You will work hands-on with PLCs, robotics, safety systems, fieldbus networks, and industrial IO to enable reliable, scalable, and repeatable production systems. We are looking for engineers who enjoy building systems from concept through commissioning and thrive in fast-paced manufacturing environments.

Responsibilities Design, develop, and commission PLC‑based control systems across process, manufacturing cells, motion control, and building automation, owning the work from initial concept through production deployment and operational handoff.

Support the stand-up of new manufacturing lines, including greenfield and brownfield deployments, equipment integration, and factory acceptance testing

Program and debug PLC software using IEC 61131-3 languages (Structured Text preferred), with a focus on readable, modular, and maintainable code with object oriented programming

Integrate and commission industrial robotics systems for part handling, assembly, inspection, and material movement

Develop and configure fieldbus and industrial networking architectures, with a strong emphasis on EtherCAT-based systems

Implement machine safety systems and interlocks in compliance with applicable safety standards (e.g., ANSI/RIA, ISO, OSHA), including the application of functional safety principles such as SIL or Performance Level (PL) where required

Design and review electrical control schematics, panel layouts, and P&IDs in coordination with Electrical Engineering and external vendors

Develop HMIs that balance operator usability with effective diagnostics and troubleshooting capability

Interface machine-level control systems with higher-level manufacturing systems such as SCADA, MES, and data historians

Troubleshoot and optimize automated equipment to improve throughput, yield, uptime, and overall equipment effectiveness (OEE)

Collaborate closely with Mechanical Engineering, Manufacturing Engineering, Quality, and Operations throughout the equipment lifecycle

Support creation, deployment, and handoff of documentation into production, including operator and maintenance training

Work with external machine builders, integrators, and suppliers to ensure system performance and compliance

Qualifications Education: Bachelor’s degree in Electrical Engineering, Controls Engineering, Mechatronics, or a related technical discipline

Experience: 3+ years of hands-on experience developing and commissioning control systems for manufacturing or industrial automation environments

Strong experience with PLC platforms used in manufacturing environments (e.g., Beckhoff, Siemens, Rockwell, or equivalent)

Demonstrated experience standing up or supporting process, manufacturing, or assembly lines, including integration of multiple machines or subsystems

Proficiency with industrial fieldbus and communication protocols, including EtherCAT (required); experience with Profinet, Ethernet/IP, CAN, or Modbus is a plus

Experience integrating sensors, actuators, servo drives, VFDs, and distributed IO in machine control systems

Solid understanding of industrial electrical systems, control panels, and relevant codes and standards (e.g., NFPA 79, NEC, UL 508A)

Strong troubleshooting skills across software, electrical, and system-level issues

Ability to work hands-on in a factory or lab environment, including occasional lifting, standing, and on-equipment debugging

Must be a U.S. citizen or national, U.S. permanent resident (current Green Card holder), or lawfully admitted into the U.S. as a refugee or granted asylum.

Desired Experience with Beckhoff TwinCAT, including EtherCAT configuration and distributed motion control

Experience integrating industrial robots (e.g., FANUC, ABB, KUKA, Universal Robots)

Familiarity with functional safety concepts such as safety PLCs, safety IO, and safe motion

Experience with machine vision systems used for inspection or alignment

Experience with SCADA platforms (e.g., Ignition) and production data collection

Experience supporting automated systems in a production or high-volume manufacturing environment

Familiarity with version control, code standards, and structured documentation practices for control systems

Greenfield manufacturing startup or rapid scale-up experience
