Controls Engineer - CODESYS / Linux IPC (Remote)

We are supporting a large-scale automation program operating across a globally distributed fleet of high-throughput material handling and robotics systems. This is not a traditional on-site controls engineering role. The environment is highly software-driven, and all work is performed remotely through Linux-based industrial control systems. Engineers operate at a systems level, diagnosing and improving deployed automation using telemetry, logs, and control logic rather than physical access to equipment.

Key Responsibilities

• Troubleshoot and resolve control system issues across distributed automation environments using remote access and system data
• Analyze alarms, system states (PackML), and performance metrics (OEE) to identify failure patterns and improvement opportunities
• Develop, modify, and deploy PLC control logic (Structured Text, Ladder, Function Block) across multiple systems
• Support deployment and stabilization of new automation features and pilot programs
• Standardize control logic and reduce configuration drift across environments
• Create diagnostic tools, runbooks, and documentation to improve repeatability and reduce resolution time
• Provide support coverage aligned to defined service windows, including evenings and weekends Required Skills & Experience
• Experience with CODESYS or equivalent platforms (CODESYS V2/V3, TwinCAT, IndraWorks, SoMachine/Machine Expert, etc.)
• Strong proficiency in IEC 61131-3, especially Structured Text
• Experience working with Linux-based systems (CLI, logs, services, remote access)
• Proven ability to troubleshoot automation systems remotely using logs, telemetry, and system data
• Background supporting industrial automation, material handling, or robotics systems Preferred Experience
• Experience with cloud-based tools or data environments (AWS, log analysis, monitoring tools)
• Familiarity with PackML, alarm management, or OEE optimization
• Experience supporting large-scale or multi-site deployments
• Exposure to version control (Git) and structured development workflows
• Scripting experience (Python or similar) Additional Information
• Fully remote (U.S. based candidates only)
• Long-term engagement supporting production systems
• Engineers will work within a distributed team supporting a large installed base of automation systems Important Note This role is best suited for engineers who are comfortable working at the intersection of controls and software. Candidates whose experience is primarily hands-on commissioning or field-only troubleshooting without exposure to remote system diagnostics may not be a fit.
