Embedded Linux Engineer

Responsibilities

• Firmware & Driver Development: Build firmware and device drivers for a new Linux-based personal computing device and its peripherals, from early prototypes through production.
• Security, Reliability, Performance: Redefine the bar for security, reliability, and performance across the Linux software stack, pushing the boundaries of what our system can achieve.
• Build Systems & CI/CD: Contribute to on-time and correct delivery of OS features by designing, implementing, and maintaining build systems and CI/CD/CT pipelines for our embedded Linux system.
• Cross-Functional Collaboration: Collaborate with electrical engineers, mechanical engineers, security engineers, and other software engineers to integrate components into a cohesive product.
• Open-Source Engagement: Work directly with upstream open-source communities – contributing patches, engaging in discussions, and ensuring our work aligns with broader ecosystem developments.

Requirements (Must-Have Qualifications)

• Linux Kernel Development: Proven experience with Linux kernel development, including writing kernel modules and device drivers.
• Strong C Programming: Strong, demonstrable coding skills in C.
• Embedded Linux Build Systems: Experience with embedded Linux build systems such as Buildroot, Yocto, or OpenWRT.
• Hardware Communication Protocols: Familiarity with various bus communication protocols (I2C, SPI, UART, PCI, USB, SDIO, etc.).
• Embedded Systems Fundamentals: Strong understanding of embedded systems concepts, including microcontrollers, memory management, and interrupt handling.
• Debugging Skills: Strong problem-solving and debugging skills in both hardware and software contexts.
• Startup Environment: Ability to work effectively in a collaborative, fast-paced startup environment.
• Communication: Excellent communication and teamwork skills.

Preferred Skills (Nice-to-Have)
