Sr Firmware Engineer

Job Description:

Key Responsibilities:

• Work with Hardware Engineers to design mixed analog and digital electronic circuits for embedded controllers, power converters and data acquisition systems.
• Develop embedded firmware for real-time control of power electronics systems, including PWM generation, ADC sampling, protection handling, and fault management.
• Model electrical systems such as power converters and design optimal digital controllers based on simulations and real test data.
• Implement real-time digital control algorithms (current, voltage) in embedded firmware.
• Integrate control software with hardware protection mechanisms such as overcurrent, overvoltage, and thermal protection.
• Design FPGA circuits and program them in VHDL/Verilog for high-speed communications, signal processing, or interface logic.
• Perform system validation using SIL, HIL, and real hardware testing, ensuring performance, stability, and reliability.
• Collaborate with hardware, firmware, control, and system engineering teams to optimize designs and improve product quality and robustness.

Qualifications:

• Master’s degree or higher in Electrical Engineering, in the area of Power Electronics, Control Engineering, or equivalent.
• Minimum 4 years of experience as an embedded software developer with solid knowledge of embedded systems architecture applied to power electronics systems.
• Proficiency in programming languages such as C/C++, with experience in bare-metal and RTOS-based firmware for real-time control applications.
• Experience developing firmware for digital control of power converters,  grid following and forming systems.
• Familiarity with RTOS (Real-Time Operating Systems).
• Strong understanding of real-time constraints, deterministic execution, interrupt handling, and task scheduling for control loops.
• Experience with digital signal processing (DSP) concepts applied to power electronics (filters, observers, transformations, control loops).
• Good understanding of debugging and testing embedded systems, including hardware-in-the-loop (HIL) and software-in-the-loop (SIL).
• In-depth understanding of microcontrollers, DSPs, microprocessors, and hardware–software interaction in power electronics systems.
• Knowledge of low-level hardware architecture, peripheral configuration (ADC, PWM, timers, DMA), software optimization, memory management, and real-time processing.
• Experience with communication protocols commonly used in power electronics systems (CAN, SPI, I2C, UART, Ethernet, Modbus, etc.).
• Strong background in system modeling/simulation and analog/digital controller design (PI, PID, state-space, observers).
• Ability to translate control algorithms from simulation environments (e.g., MATLAB/Simulink) into efficient embedded code.
• Strong problem-solving skills and ability to work with complex hardware/software interfaces.
• Demonstrated ability to work independently and collaboratively in cross-functional teams.
• Excellent communication skills and ability to work effectively in a collaborative environment.
• English – Advanced.
