Position Title: Firmware Engineer
Department: Inverter Firmware
Compensation: $87,000 - $135,000 + 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.

About the Role:

The Firmware Engineer - FPGA owns the design, development, optimization, and lifecycle support of realtime embedded firmware for inverters used in utility energy storage systems. This role requires deep expertise in Texas Instruments DSP platforms, inverter control firmware, and gridcode compliance.

Responsibilities:

• Architect, design, and implement FPGA logic for gridtied inverters and energy storage subsystems using FPGA/CPLD platforms.
• Develop synthesizable RTL (VHDL/Verilog) for timecritical functions such as data acquisition, protection logic, communications, and control offloading.
• Translate system, control, and gridcode requirements into traceable firmware requirements and robust designs.
• Implement inverter features such as grid synchronization, protections, fault handling, diagnostics, and monitoring.
• Support compliance with grid and firmware standards (UL 1741 SB, IEEE 1547, UL 1998) and certification testing activities.
• Collaborate with hardware, controls, systems, and validation teams to ensure systemlevel performance and reliability.
• Debug complex firmware issues, perform rootcause analysis, and optimize performance using lab tools and emulators.
• Participate in and lead firmware architecture reviews, code reviews, and technical risk assessments.
• Maintain clear firmware documentation and contribute to process improvement and release quality.
• 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.
• 5+ years of professional experience developing FPGA or digital logic for embedded or realtime systems.
• 3+ years of handson experience with Lattice FPGA platforms in production hardware.
• Demonstrated experience with gridtied inverters, power converters, or comparable highreliability embedded systems.
• Familiarity with inverter and gridinterconnection standards such as UL 1741 SB, IEEE 15472018, and UL 1998 is strongly preferred.
• Experience working in crossfunctional and globally distributed engineering teams.
• Strong analytical, problemsolving, documentation, and technical communication skills.
• International and domestic travel ability.
• Expert proficiency with FPGA devices and toolchains, including synthesis, place & route, timing analysis, and bitstream generation.
• Strong experience in RTL development using VHDL and/or Verilog for realtime and safetycritical applications.
• Solid understanding of clocking, CDC, timing closure, latency, and throughput optimization.
• Experience designing FPGAbased interfaces to ADCs, DACs, MCUs/DSPs, sensors, and external peripherals.
• Solid understanding of gridtied inverter operation and digital control concepts.
• Experience with gate driver control and power device protection of power semiconductor IGBT/MOSFET (i.e. with Wolfspeed, Infineon, Semikron etc.).
• Working knowledge of gridcode behavior such as antiislanding, ridethrough, and grid support functions.
• Experience with embedded communication protocols including CAN, SPI, UART, parallel interface and custom protocols.
• Familiarity with firmware interfaces to BMS, EMS, SCADA, and commissioning tools.
• Simulation experience (P-Spice, Simulink) is an asset.
• Strong grasp of modern firmware development practices, including Gitbased version control, peer reviews, and issue tracking.
• Ability to read and interpret schematics and collaborate closely with hardware designers.
• Exposure to firmware verification strategies, including simulation, integration testing, and HIL testing.
