Summary The Senior Controls Engineer will lead the design, testing, commissioning, and continuous improvement of plant-level control systems for utility-scale solar and battery energy storage projects.     This role provides technical leadership for Power Plant Controller (PPC), Energy Management System (EMS), and supervisory control solutions that support safe, reliable, and compliant plant operations. The position partners closely with internal teams, OEMs, EPCs, and operations stakeholders to define control strategies, evaluate designs, and support successful project execution from design through commercial operation.   The ideal candidate brings strong experience with renewable energy controls, technical problem solving, and cross-functional collaboration in a fast-paced project environment.   We are open to considering U.S. remote-based candidates, preferably located in the Pacific (PST) time zone.

Control Strategy Development and Implementation   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
