Senior Embedded Engineer - Firmware (Linux)

Experience – 3 to 6 years

JOB DESCRIPTION

The ideal candidate will have hands-on expertise in Linux Kernel development, device drivers, hardware bring-up, and bare-metal/RTOS-based development on ARM-based MCUs and i.MX processors. Experience with wireless technologies like BLE and Wi-Fi is highly desirable.

Key Responsibilities:

- Develop, port, and maintain Linux BSPs including bootloader (U-Boot) and Linux
- Kernel for ARM-based SoCs (e.g., NXP i.MX series, STM32MPx).
- Design and implement Linux device drivers for interfaces such as I2C, SPI, UART,USB, Ethernet, GPIO, PCIe, etc.
- Perform hardware bring-up and board diagnostics for custom hardware platforms.
- Integrate and develop software stacks for Wi-Fi, BLE, and cellular modems.
- Work with RTOS (e.g., FreeRTOS, Zephyr) on MCUs for real-time control or peripheral management.
- Develop low-level firmware in C/C++ and optimize for performance and power.
- Contribute to Yocto Project build system for customized Linux distributions.
- Collaborate with hardware and application teams to debug issues and support new platform development.
- Use tools such as JTAG debuggers, oscilloscopes, and logic analyzers for system-level debugging.
- Ensure code quality through unit testing, integration testing,



and peer code reviews.

Required Skills:

- Strong hands-on experience in Linux Kernel internals, driver development, and system programming.
- Proven expertise in i.MX processors (e.g., i.MX6/8) and ARM Cortex-A/M-based platforms.
- Deep knowledge of embedded C/C++ programming.Experience with Yocto Project, Buildroot, and embedded Linux distributions.Expertise in U-Boot and device tree customization.
- Working knowledge of BLE and Wi-Fi stack integration, including kernel-space and user-space handling.
- Experience with RTOS development and debugging on MCUs (e.g., STM32, NXP, TI).Solid understanding of hardware interfaces and schematic-level debugging.

Nice to Have:

- Exposure to Android kernel/driver development on embedded platforms.
- Familiarity with secure boot, Trusted Execution Workplace (TEE), or OTA update mechanisms.
- Experience with containers (e.g., Docker) or virtualization (e.g., QEMU) in embedded systems.
- Knowledge of networking stack and protocols such as TCP/IP, MQTT, CoAP.
- Contributions to open-source projects or upstream kernel patches.

Pay: ₹600,000.00 - ₹800,000.00 per year

Benefits:

- Provident Fund
