Custom RTOS & Low-Level Firmware Engineer

• Design and develop custom RTOS components, including:
• Scheduler
• Task infrastructure
• Inter-task communication mechanisms
• Memory management
• Interrupt handling
• Build and maintain firmware and driver development frameworks that meet real-time performance and timing constraints.
• Develop BootROM, bootloader, and initialization code for embedded systems.
• Implement and optimize low-level hardware abstraction layers (HAL) and device drivers.
• Work closely with hardware and systems engineering teams for platform bring-up and system integration.
• Apply strong knowledge of operating system data structures and algorithms to solve complex system-level problems.
• Ensure code quality, documentation, and test coverage throughout the development lifecycle.

• Strong proficiency in C programming for embedded systems.
• Solid understanding of custom RTOS development concepts.
• Deep experience with scheduling algorithms, inter-process communication, and interrupt handling.
• Experience working with embedded processor architectures such as RISC-V, ARM, or MIPS.
• Hands-on experience with:
• Bootloaders / BootROM
• Board initialization code
• Low-level driver and HAL development
• Familiarity with real-time performance tuning and debugging in embedded environments.
• Experience working with lab tools (oscilloscopes, logic analyzers, etc.) is a plus.

• Exposure to FreeRTOS or similar RTOS kernels.
• Experience with emulators, debuggers (e.g., JTAG), and performance profiling tools.
• Familiarity with secure boot or power management subsystems is an added advantage.

• Strong analytical and problem-solving skills
• Self-driven and comfortable working in fast-paced environments
• Effective verbal and written communication skills
