Must Have Skills and Responsibilities 

Global Collaboration and Technical Leadership 

• Collaborate with global technical leaders and business units to execute standardization roadmaps for PLC / HMI / VFD / SCADA / Industrial Edge & Intelligence / Sensors & Networking. 

• Drive consolidation of control strategies and templates across regions and product lines. 

• Evaluate and introduce new tools and practices such as simulation, elite coding techniques, documentation tooling, and PLC-oriented CI/CD where applicable. 

• Participate in management of Supplier relationships, including enforcement of negotiated corporate pricing. 

• Influence and guide teams through technical leadership rather than direct authority. 

Automation Library Architecture and Lifecycle Ownership 

• Architect, develop, and maintain standardized PLC & HMI libraries (AOIs / FBs, UDTs, Faceplates / Global Objects) for global reuse. 

• Lead / guide adoption of PLC / HMI libraries by our global Business Units, often helping them to restructure their legacy code into our library format. 

• Define and enforce software architecture standards, including naming conventions, parameter models, diagnostics, error handling, scalability, and performance. 

• Own versioning and release governance, including semantic versioning, backward compatibility, deprecation policies, and release documentation. 

• Manage defect and enhancement backlogs with structured triage, prioritization, and regression testing. 

• Experience applying ISA and IEC standards to control system design and documentation. 

• Familiarity with PLC testing approaches including simulation, hardware-in-the-loop, and structured regression testing. 

• Experience developing HMI or SCADA standards aligned with PLC libraries, including faceplates, alarms, diagnostics, and navigation patterns. 

Standards, Tooling, and Best Practices 

• Establish PLC coding guidelines and development workflows, including branching strategies, code reviews, testing approaches, and release gates. 

• Develop reusable utilities and accelerators such as starter projects, simulation stubs, test harnesses, and example implementations. 

• Promote modular and maintainable design aligned with ISA and IEC principles. 

Enablement, Documentation, and Mentorship 

• Maintain preferred parts lists and guidance to foster staff creation of appropriate Bill-of-Materials 

• Create high-quality technical documentation, including application notes, integration guides, interface definitions, and troubleshooting playbooks. 

• Develop enablement and training assets such as quick-start guides, sample projects, and instructional material. 

• Provide technical mentorship and remote support to global engineering teams adopting the standards. 

Good to Have (Preferred) 

• Exposure to scripting or tooling languages such as Python, C, SQL, or Excel VBA for automation, testing, or documentation. 

• Exposure to IEC 62443-aligned OT cybersecurity practices, including network segmentation, zone and conduit concepts, asset management, and industrial firewalls. 

• Experience with IT–OT convergence architectures using DMZs, VLANs, and industrial gateways such as OPC UA or MQTT. 

• Familiarity with IIoT, smart manufacturing, and digital transformation initiatives. 

• Understanding of industrial data historians and visualization tools such as OSIsoft or AVEVA PI System and PI Vision. 

Qualifications and Experience 

• Bachelor’s degree in Electrical Engineering, Instrumentation and Controls, Automation Engineering, or equivalent. 

• 8-12 Years of PLC software development experience with strong focus on modular and reusable architectures. 

Tools and Platforms 

• Rockwell Studio 5000 / Logix Designer, FactoryTalk View SE and ME 

• Siemens TIA Portal, WinCC, WinCC Unified 

• Version control systems (Git-based workflows) 

• Defect tracking, requirements management, and documentation tools 

Guidance of Others 

This role provides technical guidance, mentorship, and indirect leadership to global control system engineering teams. Strong communication skills and the ability to influence and guide others are essential.
