Position Title: Senior Control Engineer
Department: Inverter Firmware
Compensation: $95,000 - $140,000 + annual bonus
Reports To: Director of Digital Inverter Firmware
Location: Kitchener, ON (Onsite)
About the Role:The Senior Control Engineer, specializes in Hardware-in-the-Loop simulation and validation of Power Conversion Systems (PCS) used in utility-scale Battery Energy Storage Systems.
This role focuses on using real-time digital simulators to emulate grids, inverters, batteries, and power stages in order to validate control firmware, system-level behavior, protection logic, and grid-code compliance.
You will own the PCS HIL simulation environment, bridging power electronics, control algorithms, firmware, and system requirements to enable fast, repeatable, and certifiable testing.
Responsibilities:- Design, develop, and maintain Hardware-in-the-Loop (HIL) test environments for PCS and inverter control validation.
- Build real-time PCS simulation models, including grid models, filters, transformers, battery models, and protection interfaces.
- Validate inverter control algorithm firmware, protection strategies, and system behaviors under normal and abnormal operating conditions.
- Execute test cases covering grid-code compliant functionalities prior to certification testing.
- Support grid code compliance activities through documented test results and traceability.
- Expand scope of HIL platform to cover other equipment, technologies and system according to future development plan.
- Develop automated HIL test scripts and regression test suites to support continuous firmware and control validation.
- Integrate HIL testing into development workflows and release processes.
- Debug complex control and system-level issues using real-time waveforms, logs, and simulation data.
- Maintain professional documentation for HIL architectures, simulation models, test plans, and validation reports.
- Support root-cause analysis for lab and field issues by reproducing scenarios in HIL.
- Mentor junior engineers and support product lifecycle and field issue resolution.
Required Qualifications and Skills:- Bachelor's degree in Electrical Engineering, Computer Engineering, Computer Science, or related discipline. Advanced degrees in Power Electronics are preferred.
- 5+ years of professional experience in HIL testing, real-time simulation, or PCS/inverter validation.
- Demonstrated experience validating power converters system using real-time simulators.
- Experience with MATLAB/Simulink, PSCAD or model-based design workflows.
- Experience developing automated regression frameworks for inverter validation
- Experience supporting product development subject to IEC/UL / IEEE grid-interconnection standards.
- Hands-on experience working with cross-functional firmware, controls, and hardware teams.
- Strong analytical, problem-solving, documentation, and technical communication skills.
- Domestic and international travel ability.
- Strong experience with real-time HIL simulation for power electronics or grid-connected systems.
- Proficiency with HIL platforms such as OPAL-RT, Typhoon HIL, dSPACE, RTDS, or similar.
- Experience building real-time models for inverters, batteries, power systems and protection systems.
- Understanding of real-time execution constraints, model fidelity, and latency considerations.
- Solid background of power converter, especially inverter architectures, and energy storage systems.
- Experience with converter control loops, digital protection mechanisms, and system-level sequencing.
- Ability to interpret control block diagrams, firmware behavior, and electrical schematics.
- Familiarity with communication protocols such as CAN, Ethernet, SPI, UART, Modbus, and proprietary interfaces.
- Experience with test automation, scripting, or model-based validation workflows.
- Familiarity with version control (GitHub/Bitbucket), documentation practices, and structured validation processes.
- Strong analytical skills and attention to detail in test development and result interpretation.
