SENIOR ENGINEER - Firmware

Role overview

SENIOR ENGINEER - Firmware at Happiest Minds

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 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).

Required qualifications

• 3-5 Years

Preferred qualifications and 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.
• Exposure to a full-stack SoC development lifecycle: from pre-silicon to production-ready.
• Flexible growth path ? whether you want to specialize deeply or lead in the future.
