• Define standards for PLC software, Beckhoff IPCs, EtherCAT I/O, motion control, industrial networks, machine safety, diagnostics, and factory interfaces.
• Develop reusable TwinCAT software libraries, machine state models, fault handling, recovery strategies, and programming standards.
• Own controls and functional-safety architecture, including safety PLCs, safe motion, interlocks, guarding, emergency stops, and safety validation.
• Personally design, program, integrate, and commission automation equipment for pilot manufacturing lines.
• Translate successful pilot architectures into scalable equipment standards and specifications for production systems.
• Develop controls requirements, Statements of Work, design standards, and acceptance criteria for externally integrated equipment.
• Serve as the controls technical lead for systems integrators executing $20M+ automation programs.
• Lead technical design reviews across electrical systems, PLC software, robotics, motion, networking, machine safety, and factory interfaces.
• Lead controls execution through FAT, SAT, installation, commissioning, and production launch.
• Troubleshoot complex interactions between PLCs, robotics, motion systems, machine vision, instrumentation, safety systems, and factory software.
• Optimize machine sequences, cycle time, fault recovery, reliability, and OEE during production ramp.
• Maintain technical ownership until manufacturing systems achieve defined Run at Rate and production-readiness milestones.
• Mentor automation engineers and establish controls engineering best practices across Mach.

Required Qualifications

• Bachelor's degree in Electrical Engineering, Controls Engineering, Mechatronics, Mechanical Engineering, Computer Engineering, or a related discipline.
• 8+ years of experience developing industrial automation, controls, or complex electromechanical systems.
• Strong PLC programming experience and the ability to personally develop and debug production controls software.
• Demonstrated ownership of controls architecture for complex automated equipment or manufacturing systems.
• Experience taking automated equipment from design through integration, commissioning, and production.
• Experience designing or implementing machine-safety and functional-safety systems.
• Experience working directly with systems integrators, equipment OEMs, or automation suppliers.
• Strong understanding of industrial networks, distributed I/O, motion control, instrumentation, robotics, and machine integration.
• Demonstrated ability to independently troubleshoot complex equipment in a production environment.

Preferred Qualifications

• Experience with Beckhoff TwinCAT 3, particularly IEC 61131-3 Structured Text.
• Experience with Beckhoff IPCs, EtherCAT, TwinSAFE, distributed I/O, and servo motion.
• Experience serving as a controls technical lead for large, multi-machine automation or capital equipment programs.
• Experience with industrial robotics, machine vision, automated test systems, and advanced motion control.
• Experience integrating controls systems with SCADA, MES, historians, traceability, or factory data infrastructure.
• Familiarity with OPC UA, MQTT, or other machine-to-software communication architectures.
• Working knowledge of functional and machine-safety standards including ISO 13849, IEC 62061, IEC 61508, NFPA 79, and NFPA 70.
