SENIOR ENGINEER - Firmware

Happiest Minds Technologies; Bengaluru; On-site; INR 700,000 - 1,200,000; Full time

Job summary

Happiest Minds Technologies in Bengaluru/Bangalore and Pune, India, seeks an Embedded Software Engineer focused on RTOS-based software development and AVV. You will contribute across the silicon-to-software lifecycle for automotive SoCs powering EVs, ADAS, and powertrain domains.

You will bring up silicon, develop drivers, validate peripherals, and work with teams across architecture, hardware, and safety to ensure robust, scalable software for real-time MCU platforms.

Qualifications

• 3–5 years of hands-on experience in embedded systems software development.
• Strong in C/C++ programming with basic familiarity in assembly.
• Good understanding of RTOS concepts (task scheduling, ISRs, semaphores, etc.).
• Experience debugging complex multicore systems, with tools like OpenOCD, Segger J-Link, or Lauterbach.
• Experience porting or developing on FreeRTOS, Zephyr, 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).

Responsibilities

• Develop embedded software components for RTOS-based SDKs, including LLDs, HALs, RTOS abstraction layers, and BSPs.
• Create example/demo applications to showcase peripheral functionality and performance.
• Support post-silicon validation (AVV) by creating validation test apps that reuse RTOS SDK components.
• Bring up first silicon and validate critical peripherals (ADC, PWM, CAN, LIN, watchdogs, etc.).
• Support automation of lab and CI-based test execution.
• Collaborate 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.
• Provide feedback into next-gen MCU architecture based on software validation findings.
• Contribute to the wider software ecosystem, ensuring support for the architecture in open-source projects.

Job description

Embedded Software Engineer ? RTOS & Post-Silicon Validation (Automotive Real-Time MCU)

Location:

Pune / Bangalore ? India

Years of Experience:

3-5 Years

Job Summary:

Join us as an Embedded Software Engineer, focusing on RTOS-based Software Development and Application Verification & Validation (AVV). This role offers a unique opportunity to contribute across the full silicon-to-software lifecycle, ensuring high-quality, safety-critical SoC solutions for automotive applications such as EVs, ADAS, powertrain, and domain controllers.

Responsibilities:

• Develop embedded software components for RTOS-based SDKs, including Low-Level Drivers (LLDs), HALs, RTOS abstraction layers, and BSPs.
• Create example/demo applications to showcase peripheral functionality and performance.
• Support post-silicon validation (AVV) by creating validation test apps that reuse RTOS SDK components.
• Bring up first silicon and validate critical peripherals (ADC, PWM, CAN, LIN, watchdogs, etc.).
• 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:

• 3-5 years of hands-on experience in embedded systems software development.
• Strong skills in C/C++ programming, with basic familiarity in assembly.
• Good understanding of RTOS concepts (task scheduling, ISRs, semaphores, etc.).
• Experience debugging complex multicore systems, with proficiency in debugging tools (OpenOCD, Segger J-Link, Lauterbach).

• 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.

What You?ll Get:

• Opportunity to work on cutting-edge platforms with real industry adoption.
• A fast-paced, engineering-driven environment with minimal red tape.
• Mentorship from veteran CPU and embedded software engineers.
• Direct involvement in building safety-critical systems from the ground up.
