Embedded Firmware Engineer

Job Title: Embedded Firmware Engineer

Job Description

This role is for an experienced Embedded Firmware Engineer who works across both real-time RTOS firmware and Embedded Linux environments. You will design, develop, and maintain low-level software spanning MCU/MPU firmware, Linux kernel and device drivers, hardware interfaces, and heterogeneous embedded systems. You will move comfortably between real-time firmware and Linux kernel-level development while independently owning technical deliverables and collaborating closely with cross-functional engineering teams.

Responsibilities

• Develop and maintain production-quality C/C++ software across RTOS firmware and Embedded Linux platforms.
• Design and implement real-time firmware using FreeRTOS, Zephyr, or comparable RTOS environments.
• Develop and maintain Linux kernel device drivers for embedded hardware components.
• Integrate and control hardware using SPI, I2C, UART/serial, and similar embedded interfaces.
• Work with MCU/MPU-based heterogeneous systems, including inter-processor communication and shared resources.
• Configure and customize embedded Linux builds using Yocto, Buildroot, or comparable build systems.
• Perform hardware bring-up, integration, validation, and root-cause debugging across RTOS, Linux kernel, and hardware boundaries.
• Execute firmware bring-up, validation, and root-cause debugging on target hardware platforms.
• Analyze timing, concurrency, memory and resource usage, interrupts, and real-time behavior to ensure robust system performance.
• Collaborate with firmware, electrical, hardware, systems, robotics, and test teams while independently driving assigned work to completion.
• Apply sound engineering judgment, own technical tasks end-to-end, and deliver high-quality solutions with minimal oversight.
• Contribute to software testing and validation activities to ensure reliable and maintainable embedded solutions.

Essential Skills

• Bachelor's degree in Computer Science, Computer Engineering, Electrical Engineering, or a related field.
• 5+ years of professional embedded software or firmware development experience.
• Strong proficiency in C and C++ for low-level embedded and systems development.
• Professional RTOS development experience, such as FreeRTOS, Zephyr, or a comparable RTOS.
• Hands-on Embedded Linux experience, including professional Linux kernel device-driver development.
• Experience with embedded Linux build systems such as Yocto, Buildroot, or comparable platforms.
• Strong MCU and MPU fundamentals, including hands-on integration using SPI, I2C, and UART/serial interfaces.
• Strong debugging skills across RTOS, Linux kernel, and hardware boundaries.
• Experience with software testing, validation, and test engineering in embedded environments.
• Demonstrated ownership of technical work, sound engineering judgment, and the ability to deliver with minimal guidance.

Additional Skills & Qualifications

• Experience with heterogeneous systems involving MCUs, MPUs, DSPs, inter-processor communication, or shared memory.
• Professional DSP or digital signal-processing experience.
• Experience with board support packages (BSPs), device trees, bootloaders, JTAG-based debugging, or bare-metal firmware.
• Background in production robotics, autonomous systems, industrial equipment, automotive, or similar complex embedded products.
• Experience with Embedded Linux platform bring-up from initial hardware integration through system validation.
• Experience developing firmware or software for real-time closed-loop and feedback control systems.
• Familiarity with real-time analysis of timing, concurrency, and interrupt-driven behavior in embedded systems.
