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 current 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

Perks:
Provident Fund
