Senior HIL Engineer

Build the clean energy grid of the future. At Doosan GridTech, we're not just imagining a smarter, more sustainable grid; we're enabling it through advanced software solutions. We deliver intelligent, vendor-neutral software and services that help utilities, developers, and independent power producers improve the visibility, control, performance, and reliability of energy storage and renewable power systems. As Senior HIL Engineer, you will develop real-time simulation and hardware-in-the-loop capabilities that reduce integration risk and prove plant controls before field deployment. You will work across product and customer lifecycles, applying disciplined engineering, clear communication, and practical judgment to deliver safe, reliable, and supportable outcomes. What you will do: Responsibilities Lead development of high-fidelity real-time plant and equipment models and automated HIL validation campaigns. Design HIL architecture and interfaces for PPC, SCADA, RTU, networks, inverters, meters, and customer control signals. Guide model validation, test coverage, lab configuration control, and analysis of complex controls interactions. Develop and maintain real-time models, I/O interfaces, communications, test harnesses, automation scripts and automated HIL test scenarios. Integrate PPC, SCADA, RTU, protection, networking, inverter, and balance-of-plant interfaces into representative test environments. Translate system requirements and failure modes into traceable functional, performance, boundary, fault, and recovery tests. Analyze and document test results, reproduce issues, support root-cause investigation, and provide clear release and commissioning evidence. Continuously improve model fidelity, lab configuration control, automation, utilization, safety, documentation, and reusable test assets. What you will bring: Required Qualifications Five or more years of directly relevant professional experience delivering complex technical work in production or customer environments. Bachelor’s degree in electrical, controls, power systems, or computer engineering; equivalent relevant experience may be considered. Experience with real-time simulation, HIL, controls testing, power-system modeling, or industrial automation integration. Experience with Typhoon HIL is required. Knowledge of power systems, control loops, I/O, networking, industrial protocols, data acquisition, and test automation. Strong troubleshooting, scripting, documentation, and cross-functional communication skills. Must live in the Bend area or able to commute 25-30% of your time. Not required but nice to have: Desired Qualifications Experience testing BESS, inverter-based resources, PPC, SCADA, RTU, or grid-code behavior. Experience with OPAL-RT, RTDS, MATLAB/Simulink, PSCAD, or comparable platforms. Vendor HIL certification, graduate power/controls degree, or Professional Engineer license.
