Job description

Position- MCAL Driver with Embedded C Developer

Location: Pune / Bangalore

Years of Experience: 5-8 Years

Job Summary: We are seeking a talented Embedded Software Engineer to join our Automotive MCU Platform Team.

The ideal candidate will have strong embedded development knowledge, focusing on RTOS-based software development and application verification & validation (AVV).

You will play a crucial role in shaping the future of embedded control systems for automotive applications, contributing across the full silicon-to-software lifecycle.

Responsibilities:

• Develop embedded software components for RTOS-based SDKs, including low-level drivers (LLDs), hardware abstraction layers (HALs), RTOS abstraction layers, and board support packages (BSPs).
• Create example/demo applications to showcase peripheral functionality and performance.
• Support post-silicon validation (AVV) by creating validation test applications that reuse RTOS SDK components.
• Bring up first silicon and validate critical peripherals such as ADC, PWM, CAN, LIN, and watchdogs.
• Support automation of lab and CI-based test execution.
• Collaborate across teams, working closely with architecture, hardware, safety, and tools teams to align software with silicon capabilities and roadmap.
• Contribute to reference software and tooling to aid customers in bootstrapping their own designs.
• Analyze and debug complex issues using emulators, silicon, and debug tools like OpenOCD, J-Link, or Lauterbach.
• Provide feedback into next-gen MCU architecture based on software validation findings.
• Contribute to the wider software ecosystem, ensuring support for the architecture in various open-source projects.

Mandatory Skills:

• 5 to 8 years of hands-on experience in embedded systems software development.
• Strong skills in Embedded C programming, with basic familiarity in assembly.
• Good understanding of RTOS concepts, including task scheduling, ISRs, and semaphores.
• Experience debugging complex multicore systems and familiarity with debugging tools (OpenOCD, Segger J-Link, Lauterbach).
• Experience porting or developing on FreeRTOS, AUTOSAR OS, or similar platforms.
• Familiarity with bare-metal development, memory-mapped IO, and driver development.
• Experience in bring-up and debugging on real silicon or FPGA platforms.
• Knowledge of automotive interfaces and protocols: CAN, LIN, SPI, I2C, UART.
• Practical exposure to test automation, scripting (Python/bash), and version control (git).

Preferred Skills:

• Exposure to ASIL-D software development, ISO 26262 process, or safety validation.
• Prior involvement in post-silicon AVV or hardware-in-the-loop (HIL) test setups.
• Familiarity with RISC-V architecture, instruction sets, and toolchains.
• Experience developing or validating motor control, powertrain, or safety-critical firmware.
• Knowledge of bootloaders, secure update, or system startup firmware.
• Advantage to candidates with prior Autosar MCAL development experience.

A good candidate with strong C skills and Autosar BSW integration experience will also be considered, but first preference will be given to those with hands-on development experience for MCAL.
