Position Title: Senior Power Electronics Control Engineer
Department: Inverter Firmware
Compensation: $95,000 - $140,000 + annual bonus
Reports To: Director of Digital Inverter Firmware
Location: Kitchener, ON (Onsite)

CS Digital is a digital technology startup focused on providing state-of-the-art digital technology for power solutions. Our first goal is to build a North American based inverter control board, firmware and energy station controller for the BESS industry to compliment Canadian Solar's String Power Conversion System Medium Voltage Skid for the Battery Energy Storage System (BESS) industry.

Who You Are:

The Senior Power Electronics Control Engineer, specializes in Hardware-in-the-Loop simulation and validation of Power Conversion Systems (PCS) used in utilityscale Battery Energy Storage Systems.

This role focuses on using realtime digital simulators to emulate grids, inverters, batteries, and power stages in order to develop and validate control firmware, systemlevel behavior, protection logic, and gridcode 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 HardwareintheLoop (HIL) test environments for PCS and inverter control validation.
• Build realtime PCS simulation models, including grid models, filters, transformers, battery models, and protection interfaces.
• Develop and 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 systemlevel issues using realtime waveforms, logs, and simulation data.
• Maintain professional documentation for HIL architectures, simulation models, test plans, and validation reports.
• Support rootcause analysis for lab and field issues by reproducing scenarios in HIL.
• Conduct testing of the PCS hardware.
• Mentor junior engineers and support product lifecycle and field issue resolution.

• Strong experience with realtime HIL simulation for power electronics or gridconnected systems.
• Proficiency with HIL platforms such as OPALRT, Typhoon HIL, dSPACE, RTDS, or similar.
• Experience building realtime models for inverters, batteries, power systems and protection systems.
• Understanding of realtime 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 systemlevel 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 modelbased 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.

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, realtime simulation, or PCS/inverter validation.
• Demonstrated experience validating power converters system using real-time simulators.
• Experience with MATLAB/Simulink, PSCAD or modelbased design workflows.
• Experience of power converter experimental testing in laboratory set up.
• Experience developing automated regression frameworks for inverter validation
• Experience supporting product development subject to IEC/UL / IEEE gridinterconnection standards.
• Handson experience working with crossfunctional firmware, controls, and hardware teams.
• Strong analytical, problemsolving, documentation, and technical communication skills.
• Domestic and international travel ability.
