• Serve as a senior technical contributor and subject‑matter expert for complex migrations of FactoryLink (FLink) applications to Siemens WinCC within a structured, team-based project environment
• Perform in-depth analysis of legacy FLink architectures and design robust WinCC solutions that preserve functionality while improving performance, maintainability, and standardization
• Architect, develop, and validate advanced WinCC screens, scripts, system configurations, and alarm/event handling
• Design, review, and optimize VBScript (VBS) and C-based logic to support migration strategy, customization, diagnostics, and long-term system stability
• Provide technical leadership and mentorship to less-experienced engineers, including guidance on best practices, coding standards, and troubleshooting approaches
• Assume technical ownership for assigned migration scopes, including issue triage, root-cause analysis, risk assessment, and resolution of complex or ambiguous engineering challenges
• Actively contribute to and, as appropriate, lead technical design reviews, system testing, and customer acceptance activities
• Contribute to continuous improvement by creating and maintaining engineering standards, technical documentation, and reusable migration assets, and by sharing lessons learned across projects

Requirements:

• 8+ years extensive hands-on experience with Siemens WinCC, including system architecture and advanced configuration
• Strong proficiency in VBScript (VBS) and C, with demonstrated experience supporting complex automation systems
• Proven experience leading or technically owning work within a team-based engineering or migration environment

• Advanced analytical and problem-solving skills, with the ability to work effectively with ambiguous, incomplete, or undocumented legacy requirements
• Strong communication skills, capable of interfacing with project teams, management, and customers on technical matters
• Legally authorized to work in the United States on a continual and permanent basis without company sponsorship
• Advanced, hands-on experience with FactoryLink (FLink) systems, including detailed analysis of legacy architectures and behaviors to support complex migration efforts
• Demonstrated experience serving in a senior technical role on automation system migration, modernization, or lifecycle management projects, with accountability for technical outcomes
• Proven capability in customer-facing project environments, including participation in technical alignment discussions, issue resolution, and support of customer acceptance activities
• Experience working on medium to high complexity projects with limited oversight, applying Siemens engineering standards and best practices
