About the Job

Requirements

  • A bachelor's degree or higher in Engineering, Control Systems, Computer Science, or a related field.
  • At least 3 years of IEC 61131-3/PLC programming experience; experience in Codesys or AcSELerator is preferred.
  • Proficiency in IEC 61131-3 programming, with AcSELerator for SEL controllers and Codesys as the primary IDEs; familiarity with Diagram Builder; and proficiency using traces, cross-references, breakpoints, and watch lists.
  • Working knowledge of industrial protocols, including Modbus-TCP, DNP3, OPC-UA, and C37.118.
  • A solid understanding of grid functionality, including Primary Frequency Response (PFR), Automatic Voltage Regulation (AVR), active and reactive power closed-loop control, capacitor bank functionality, and underlying principles.
  • Familiarity with Utility/ISO testing and interconnection requirements, including ERCOT, PJM, BPA, IEEE 2800, and NERC.
  • Exposure to Power Plant Controller (PPC) design, configuration, and commissioning.

Responsibilities

  • Execute controls design for utility-scale solar, battery energy storage system (BESS), and hybrid projects under senior engineers’ guidance, including reviewing project scope to identify project-specific requirements and deviations from the standard controls product offering.
  • Program and commission SEL controllers using AcSELerator, and develop control logic in Codesys using IEC 61131-3 structured text and continuous function charts.
  • Follow the controls development process for project-specific development work, including documenting requirements, developing logic, testing in a simulated or lab environment, and documenting test results.
  • Implement and validate closed-loop Active Power and Reactive Power, AVR, and PFR algorithms.
  • Maintain version control for code artifacts according to the established procedure using Bitbucket.
  • Troubleshoot SCADA and controls issues using Wireshark, breakpoints, cross-references, and watch list tools, escalating complex issues to senior engineers as needed.
  • Produce project deliverables, including System Architecture Diagrams, Control Narratives, Logic Diagrams, commissioning documents, and operator manuals.
  • 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 Factory Acceptance Tests (FATs) and customer-facing presentations with coaching from senior engineers.
  • 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, communicating to non-technical audiences with supporting materials prepared in advance.
  • Flag technical risks and schedule pressures to the project management team with context and proposed solutions.
  • Maintain Jira tickets daily with thorough detail, following Jira best practices.
  • Deliver high-quality work across multiple concurrent projects, seeking guidance when needed.
  • Use standardized platforms and tools efficiently and maintain full adherence to Terabase quality processes.
  • Develop technical skills through code reviews, feedback, and FAT participation alongside senior engineers.
  • Complete project deliverables on time, within scope, and in accordance with Utility/ISO regulatory standards.
  • Keep Jira, version control, and documentation consistently maintained without follow-up from management.
  • Build 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.

Desired Qualifications

  • At least 2 years of utility-scale renewable power plant controls experience (solar, BESS, or hybrid), including exposure to project-specific development work, FAT, commissioning, and Site Acceptance Test (SAT).
  • Experience with Codesys or AcSELerator.
  • Familiarity with PSCAD, PSSE, and/or TSAT modeling processes for utility-scale sites.
  • Exposure to hardware-in-the-loop (HIL) hardware such as RTDS, OPAL-RT, Speedgoat, or Typhoon.
