We are looking for an Embedded Software Engineer with strong experience in bare-metal and RTOS-based development to design, implement, and validate low-level drivers, networking integration, and real-time control applications on embedded platforms.

Key Responsibilities :

- Design, develop, and validate low-level drivers for on-chip IPs (UART, SPI, I2C, Timers, GPIO, CAN, Crypto) in both bare-metal and RTOS (e.g., FreeRTOS) environments.

- Implement initialization, interrupt-driven and DMA-based data transfer (where applicable), and configuration APIs for communication and control peripherals.

- Develop RTOS-compatible driver APIs, including interrupt handlers and DMA support, along with unit test applications for functional validation and regression testing.

- Port and integrate the LwIP TCP/IP stack on the target RTOS, interfacing with Ethernet MAC and PHY drivers.

- Validate network functionality using TCP/UDP echo server/client demos and perform performance tuning and memory footprint optimization of the stack.

Develop drivers and demo applications for real-time control IPs, including :

- Data acquisition and conversion: SAR ADC with BIST, Sigma-Delta ADC, DAC for waveform generation and voltage control.

- Analog post-processing blocks: Filters, thresholding, comparator logic, and event generation using comparators.

- PWM generation: High-speed and low-speed PWM for fine/coarse control, including dead-time insertion for motor/actuator control.

- Implement real-time signal acquisition and processing flows, including closed-loop control loops where ADC inputs drive PWM outputs.

- Create demo applications that showcase system behavior and control algorithms, with visualization and logging via UART or network interfaces.

- Collaborate with hardware, systems, and test teams to review specifications, debug issues, and ensure robust, production-quality embedded software.

Required Qualifications :

- Bachelor's or Master's degree in Electronics, Electrical, Computer Engineering, or related field.

- Strong experience in embedded C programming and microcontroller/microprocessor-based development.

- Hands-on experience with bare-metal firmware and RTOS (preferably FreeRTOS) including tasks, ISRs, and synchronization mechanisms.

- Solid understanding of communication interfaces: UART, SPI, I2C, CAN, GPIO, Timers, and basic cryptographic IP usage (AES/SHA/RNG).

- Experience with TCP/IP networking on embedded systems, ideally with LwIP or similar lightweight stacks.

- Familiarity with ADCs, DACs, comparators, PWM generation, and real-time control concepts.

- Proficiency with embedded development tools: IDEs, debuggers, oscilloscopes, logic analyzers, and protocol analyzers.

- Strong problem-solving, debugging, and documentation skills, with the ability to work in a cross-functional engineering team.

Preferred Skills :

- Experience with Ethernet MAC/PHY bring-up and debugging at the driver level.

- Knowledge of control systems, digital signal processing, or motor control.

- Experience writing unit tests and hardware validation demos for low-level drivers.

- Exposure to safety- or reliability-focused development (e.g., BIST, diagnostics).
