Job description

Job Description: Senior Embedded Software Engineer

Experience: Senior (5+ years)

Location: Bengaluru (on-site)

About the Role

We are looking for a Senior Embedded Software Engineer to develop reliable, high-performance firmware for next-generation radio communication and defense systems. You will work closely with hardware, FPGA, and RF teams to build robust embedded platforms running on STM32 and similar microcontroller-based systems.

This role requires deep expertise in bare-metal programming, real-time operating systems, and low-level hardware interfacing, along with the ability to design software that operates reliably in mission-critical environments.

Key Responsibilities

• Design, develop, and maintain embedded firmware for STM32-based systems.
• Develop low-level drivers and board support packages (BSP) for peripherals and custom hardware.
• Implement real-time embedded software using RTOS frameworks.
• Work extensively with bare-metal programming, interrupts, timers, and memory management.
• Interface with hardware components such as radios, ADC/DACs, sensors, and communication modules.
• Develop and optimize communication protocols and data handling pipelines.
• Perform system bring-up, debugging, and validation on new hardware platforms.
• Collaborate closely with hardware, RF, and FPGA teams for system integration.
• Debug complex issues using oscilloscopes, logic analyzers, JTAG/SWD debuggers.
• Write and maintain technical documentation, firmware architecture documents, and test procedures.
• Participate in code reviews and maintain high standards for reliability and maintainability.

Required Qualifications

• Bachelors or Master’s degree in Electrical Engineering, Computer Engineering or a related field.
• 5+ years of professional experience in embedded firmware development.
• Strong proficiency in C/C++ for embedded systems.
• Extensive experience with STM32 microcontrollers or similar ARM Cortex-M platforms.
• Strong understanding of bare-metal programming and low-level hardware control.
• Hands-on experience with RTOS (e.g., FreeRTOS, ThreadX, or similar).
• Experience developing device drivers for SPI, I2C, UART, CAN, GPIO, and timers.
• Strong debugging skills using JTAG/SWD tools and hardware debugging instruments.
• Familiarity with Git-based development workflows.

Preferred Qualifications

• Experience working on radio communication systems or RF hardware.
• Familiarity with defense, aerospace, or mission-critical embedded systems.
• Experience with high-speed data interfaces and real-time streaming systems.
• Knowledge of signal processing concepts used in radio systems.
• Experience with embedded bootloaders and firmware update mechanisms.
• Exposure to low-power embedded system design.
• Experience integrating systems with FPGA-based processing platforms.

Key Skills

• Languages: C, C++
• Platforms: STM32, Raspberry Pi, ARM Cortex-M
• RTOS: FreeRTOS, ThreadX or similar
• Interfaces: SPI, I2C, UART, CAN, GPIO
• Debugging: JTAG/SWD, Oscilloscope, Logic Analyzer
• Version Control: Git
