• 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.
• Contribute to feature development, algorithm refinement, and performance optimization.
• Collaborate cross-functionally with project engineering and product management.
• Validation & Testing
• 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.
• Documentation & Engineering Rigor
• 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.
• Project support
• Provide technical expertise during project implementation, commissioning, or issue resolution.
• Support troubleshooting and root cause analysis for deployed systems

• Demonstrated excellence in documentation and technical communication.
• Ability to clearly convey validation results and technical findings to engineering teams and stakeholders.
• Self-sufficient and proactive — able to own features from concept through validation

Preferred Qualifications

• Experience with utility-scale renewable generation (PV, BESS, hybrid plants) or traditional power generation.
• MATLAB / Simulink modeling experience.
• Power systems analysis experience (PSCAD, PSS®E, or equivalent tools).
• Experience with Hardware-in-the-Loop (HIL) systems such as OPAL-RT, Speedgoat or RTDS
• Familiarity with grid interconnection requirements and plant-level control strategies.
• Experience developing products in a structured product lifecycle environment.
