: Embedded Software Engineer Drivers, RTOS Real-Time Control

Experience: 4 8 Years

Qualifications: Bachelor s / Master s degree in Electronics/Computer Science/SW Engineering

Location: Pune

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.

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