Design, develop, and maintain control logic for Terabase plant-level controllers using IEC-61131-3 platforms (e.g., Codesys, AcSELerator, or equivalent).
Architect modular, scalable, and maintainable control solutions across multiple product lines.
Debug, trace, and resolve complex control system issues at both software and system levels.
Collaborate cross-functionally with project engineering and product management.
Develop and execute structured test plans for new product features and releases.
Support and enhance Hardware-in-the-Loop (HIL) environments for controller validation.
Analyze and interpret system performance data to validate functional and grid compliance requirements.
Clearly document and communicate test results to internal and external stakeholders.
Produce professional-grade documentation, which may include functional specifications, test plans and validation reports, and release documentation.
Maintain strong configuration management and change control discipline.
Present technical findings in a clear, structured, and professional manner.
Provide technical expertise during project implementation, commissioning, or issue resolution.
Support troubleshooting and root cause analysis for deployed systems
