Responsibilities
Architecture, design, development, and deployment of Zephyr-based firmware for hyperscale server and rack management platforms. This includes kernel configuration, board bring-up, and subsystem integration
Develop and maintain device drivers, subsystems, and middleware layers for sensors, connectivity, power management, storage, and peripherals
Design and implement robust and scalable firmware interfaces for telemetry, power/thermal controls, remote manageability, and firmware update infrastructure
Perform board configuration (DTS, Kconfig, build system) and debug low-level issues
Collaborate with hardware teams and ODM partners through all phases of the design and development lifecycle. This includes schematic reviews, validation of interfaces, and supporting board bring-up and hardware validation
Implement secure boot, firmware update mechanisms (MCUboot, DFU), and over-the-air (OTA) functionality when required
Develop automated unit tests, integration tests, and hardware-in-the-loop testing using Zephyr’s testing frameworks (Twister, ztest)
Guide and support integration of firmware into CI/CD pipelines, including automated builds, regression testing, static analysis, and deployment workflows
Partner with hardware, BMC/RMC, security, systems, and validation teams to drive alignment across the entire platform stack
Debug complex hardware/firmware/system issues in lab and production environments. Provide debugging and root-cause analysis using tools such as JTAG/SWD, logic analyzers, and Zephyr tracing/logging systems
Qualification

Experience with ARM Cortex-M or similar MCU architectures
Solid understanding of SPI, I²C, UART, CanBus, PWM, GPIO, interrupts, DMA, and other low-level interfaces
Familiarity with version control (Git), CI/CD workflows, and code-review practices
Strong debugging abilities with embedded hardware and software tools
Experience with code static analysis tools and vulnerability scanners
Experience with system-level debug tools such as logic analyzers, JTAG, and GDB
Preferred
Experience contributing to open-source RTOS projects, ideally Zephyr
Background in networking stacks supported by Zephyr
Knowledge of secure firmware architectures, trusted execution environments, or cryptography libraries used in embedded systems
Experience with MCUboot, OTA pipelines, or secure firmware provisioning
Proficiency with Python for automation, tooling, or testing
