• Design, develop, and maintain plant-level control logic for utility-scale solar PV and BESS facilities, including PPC, EMS, and supervisory control systems. 

• Develop control strategies for active power control (APC), reactive power control (RPC), frequency response, voltage regulation, ramp rate limiting, and state-of-charge (SOC) management for hybrid solar and storage facilities, ensuring performance under expected grid operating conditions. 

• Develop control logic in IEC-61131-3 environments such as Codesys, AcSELerator, Beckhoff TwinCAT, or equivalent platforms. 

• Review OEM and EPC-supplied control strategies and design documentation, identify gaps and risks, and provide recommendations that support successful commissioning and long-term operational performance. 

• Define and support control interfaces for inverter OEMs and BESS vendors, including protocols such as Modbus, DNP3, and IEC 61850. 

Controller Modeling and Validation 

• Develop and review dynamic controller models in PSS/E to support interconnection and controls validation activities. 

• Support EMT modeling and validation activities in PSCAD/EMTDC to identify and resolve control design issues before field implementation. 

• Support NERC MOD-026 and MOD-027 submissions and respond to ISO/RTO model review comments alongside the power systems team. 

Testing, Commissioning, and Issue Resolution 

• Develop structured test plans for new control features and product releases, with clear acceptance criteria and documented pass/fail expectations. 

• Support HIL testing environments (RTDS, OPAL-RT, or equivalent) for controller validation before hardware ever touches a real plant. 

• Lead or support factory and site acceptance testing (FAT/SAT), including setpoint verification, alarm and trip logic validation, and SCADA communications checkout, while escalating issues and driving resolution as needed. 

• Support root cause analysis and corrective action development for post-commercial-operation issues, ensuring lessons learned are incorporated into future designs and processes. 

Technical Standards and Documentation 

• Ensure control designs comply with applicable standards, including IEEE 1547, IEEE 2800, relevant NERC requirements, and project interconnection obligations. 

• Develop clear and complete documentation, including functional specifications, logic descriptions, I/O lists, test procedures, and commissioning reports that support consistency, maintainability, and knowledge transfer. 

• Stay current on evolving inverter-based resource grid code requirements and apply those insights to engineering standards and project delivery. 

Cross-Functional Collaboration and Technical Leadership 

• Partner with project development, engineering, and construction teams to support equipment selection, vendor evaluation, and early identification of controls-related risks. 

• Collaborate with SCADA, commissioning, and operations teams to support reliable plant performance through startup and ongoing operations. 

• Provide technical guidance to less-experienced engineers through knowledge sharing, design review, and coaching to support team capability and quality outcomes.
