Position 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.
Key Responsibilities
Control Strategy Development and Implementation
Design develop andmaintainplant-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 IECenvironments such asCodesysAcSELerator BeckhoffTwinCAT or equivalent platforms.
Review OEM and EPC-supplied control strategies and design documentationidentifygaps 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 andcontrolsvalidation activities.
Support EMT modeling and validation activities in PSCAD/EMTDC toidentifyand 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 designscomply withapplicable 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 ofcontrols-related risks.
Collaborate with SCADA commissioning and operations teams to support reliable plant performance through startup and ongoing operations.
Providetechnical guidance to less-experienced engineers through knowledge sharing design review and coaching to support team capability and quality outcomes.
