Role Overview
Job Description Embedded Firmware for Power Electronics
you will be responsible for the end-to-end design, architecture, development, and validation of embedded control platforms for next-generation power electronic systems—including DC/DC converters, inverters, motor drives, battery management systems and EV charging solutions. Bridging hardware development and real-time embedded firmware implementation, you will drive end-to-end integration, ensuring robust signal integrity, functional safety Compliance, and deliver robust, production-ready solutions for Power Electronics in various domains. This role requires hands-on ownership, cross-functional collaboration, and a commitment to high-performance, scalable embedded design.
Key Responsibilities
- Develop real-time firmware in C/C++ for microcontrollers, DSPs, and FPGAs, implementing control algorithms (PID/state machines, voltage/current regulation), PWM strategies (soft start/stop, dead-time control), diagnostics, and communication protocols (CAN, SPI, I²C, UART).
- Develop low level drivers for controllers.
- Simulate and verify control strategies using MATLAB/Simulink and PLECS; support model-based design and HIL testing.
- Ensure compliance with IEC, UL, and other relevant safety, regulatory standards, supporting diagnostics, fault handling and system protection.
- Conduct hardware bring-up, interface testing, and system-level debugging using oscilloscopes, logic analyzers, JTAG, and power analysers.
- Collaborate with cross-functional teams (power electronics, mechanical, systems, validation) to define control architectures, timing constraints, safety-critical behaviours a nd ensure seamless hardware-software integration.
- Generate and maintain comprehensive design documentation, including firmware architecture, test protocols, safety plans, and firmware verification reports
- Support DFM, DFMEA, and HIL testing activities, contributing to design refinement and product maturity from prototype to production.
- Knowledge of embedded hardware platforms for power electronics systems, including control boards, analog/digital, mixed-signal interface design, sensor integration, and protection strategy implementation for DC/DC, AC/DC, and inverter topologies
Required Qualifications
- B.TECH/M.Tech in Embedded Systems, Power Electronics, or a related discipline.
- 3-6 years of experience in embedded hardware and firmware development for power electronic systems in industrial and automotive sectors
- Proficiency in embedded C/C++, real-time control development, real-time system programming, peripheral configuration and mixed-signal hardware design.
- Strong hands-on experience with microcontrollers and DSPs (e.g., TI C2000, STM32, Infineon), FPGAs, and communication protocols (CAN, SPI, I²C, UART)
- Familiarity with tools like Code Composer Studio (TI), Keil, IAR, STM32Cube.
- Familiarity with RTOS (e.g., FreeRTOS, TI-RTOS), watchdog implementations, fail-safe architectures, and functional safety diagnostics (ASIL compliance)
- Experience with LAB tools (such as oscilloscopes, logic analyzers, power analyzers, etc.)
- Exposure to model-based design and simulation environment (MATLAB/Simulink, PLECS, LTspice) and version control systems (e.g., Git)
Preferred Qualifications
- Experience with high-voltage power converters, traction inverters, or motor drive control systems
- Familiarity with model-based development (MIL/SIL/HIL), auto-code generation (e.g., Simulink Coder), and control validation workflows.
- Understanding of ISO 26262 safety lifecycle, including documentation practices and compliance support
- Knowledge of secure embedded architectures, firmware modularization, and OTA update strategies including secure bootloaders
- Strong collaboration, system-level thinking, and documentation skills, with a passion for code quality and continuous improvement
- Understanding in schematic design, PCB layout practices.
- Knowledge of EMI/EMC mitigation, analog/digital mixed signal interfacing, thermal design, and high-voltage design practices
- Exposure to cybersecurity principles, diagnostics frameworks, and robust communication stacks for automotive or industrial systems
