Will consider Remote for candidates not local to the San Antonio, TX area
Our client is seeking a Sr. Embedded Linux Platform Engineer to take technical ownership of the low-level Linux platform supporting a new generation of secure, purpose-built hardware products. This is a highly hands-on engineering position for someone who works comfortably at the intersection of embedded Linux, custom hardware and production systems. The ideal candidate has personally helped take (and can explain/demonstrate their contribution) new embedded hardware from initial board bring-up through a stable, secure, production-ready platform. You'll work directly with hardware and software engineering teams and have significant ownership over the Linux platform, BSPs, hardware interfaces, system performance and platform security.
Requirements:
• 5+ years of professional Embedded Linux development experience.
• Strong C programming and debugging skills in embedded or hardware-adjacent environments.
• Hands-on experience with Buildroot and/or Yocto.
• Strong working knowledge of Linux kernel configuration, device trees, BSPs, bootloaders such as U-Boot, kernel modules and driver integration.
• Experience bringing new embedded hardware platforms or board revisions into Linux.
• Hands-on experience with several hardware interfaces such as I²C, SPI, UART, GPIO, PCIe, USB, DMA and interrupts.
• Ability to read schematics and datasheets and troubleshoot hardware using appropriate lab equipment.
• Experience with Linux networking, Ethernet controllers/drivers and network performance.
• Experience delivering embedded platforms that progressed beyond prototype development into production or customer-facing products.
• Strong Git and software configuration-management practices.
Responsibilities:
• Configure and customize Linux kernels, device trees, bootloaders and root file systems for embedded hardware platforms.
• Develop and maintain Board Support Packages (BSPs) across new hardware and board revisions.
• Develop or adapt kernel drivers and user-space services when existing interfaces are insufficient.
• Use schematics, datasheets, oscilloscopes, logic analyzers and related lab equipment to troubleshoot hardware/software integration issues.
• Support secure boot, trusted boot processes and platform chain-of-trust architecture.
• Integrate technologies such as TPMs, secure elements and hardware-backed security capabilities.
• Integrate and optimize high-speed Ethernet and PCIe-connected networking.
• Configure Ethernet controllers, PHYs and associated Linux drivers.
