Sr. Project Controls Engineer

About this role

Role Purpose The Project Controls Engineer supports the design, configuration, commissioning, and documentation of plant control systems for utility-scale solar, storage, and hybrid renewable energy projects. This engineer executes project work with guidance from senior engineers, applies working knowledge of grid functionality and Utility/ISO standards, and contributes to the continuous improvement of product standards.

Approximately 90% of this role is project execution, while up to 10% is continuous improvement and product development. Responsibilities Project Execution & Technical Delivery (~90%) • Execute controls design for utility-scale solar, BESS, and hybrid projects under the guidance of senior engineers, including review of the project scope to identify project-specific requirements and deviations from the standard Terabase controls product offering.

• Program and commission SEL controllers using AcSELerator; develop control logic in Codesys using IEC 61131-3 structured text and continuous function charts • Follow the controls development process for any project-specific development work, including documentation of requirements, logic development, testing in a simulated/lab environment and documentation of test results. • Implement and validate closed-loop Active Power and Reactive Power, AVR and PFR Algorithms • Maintain version control for all code artifacts according to established version control procedure (Bitbucket) • Troubleshoot SCADA and controls issues using Wireshark, breakpoints, cross-reference, and watch list tools, escalating complex issues to senior engineers as needed • Produce project deliverables: System Architecture Diagrams, Control Narratives, Logic Diagrams, commissioning documents, and operator manuals Product & Process Improvement (~10%) • Contribute to new feature development and bug fixes in collaboration with the Product Engineering team • Prepare technical and non-technical documentation for review by senior controls engineers • Participate in the Continuous Improvement and Lessons Learned program, sharing field insights to inform product standards and templates • Prepare for FATs and customer-facing presentations with coaching from senior engineers Stakeholder Communication & Collaboration • Support senior engineers as a controls technical contact for EPCs, asset owners, and grid operators through project execution, FAT, and commissioning • Support FATs and lead assigned portions as formal presentations; communicate to non-technical audiences with supporting materials prepared in advance • Flag technical risks and schedule pressures to project management team with context and proposed solutions • Maintain Jira tickets daily with thorough detail, following Jira best practices Expectations & Success Indicators • Deliver high-quality work across multiple concurrent projects with ownership and urgency, seeking guidance when needed • Leverage standardized platforms and tools to work efficiently • Maintain 100% adherence to Terabase quality processes • Actively develop technical skills through code reviews, feedback, and FAT participation alongside senior engineers • Project deliverables completed on time, within scope, and meeting Utility/ISO regulatory standards • Jira, version control, and documentation consistently maintained without follow-up from management • Build growing expertise in Terabase SCADA and Utility-Scale grid controls, progressing toward independent project ownership • Travel up to 10% for on-site commissioning, FAT, and customer engagements Requirements Requirements Education & Experience • Bachelor’s degree or higher in Engineering, Control Systems, Computer Science, or related field • 3+ years of IEC 61131-3/PLC programming experience, preferably in Codesys or AcSELerator environment • 2+ year of utility-scale renewable power plant controls experience (solar, BESS, or hybrid) preferred, including exposure to project-specific development work, Factory Acceptance Test (FAT), commissioning and Site Acceptance Test (SAT) Technical Skills • Proficient IEC 61131-3 programming; primary IDE is AcSELerator (SEL controllers) and Codesys, familiarity with Diagram Builder; proficiency with using traces, cross-references, breakpoints, and watch lists • Working knowledge of industrial protocols: Modbus-TCP, DNP3, OPC-UA, C37.118, etc.
