This role bridges hardware and application software by owning the Linux platform, Board Support Package (BSP), security architecture, and hardware interfaces that enable our cryptographic applications.\nThe ideal candidate has deep experience with embedded Linux, Buildroot, kernel and device-tree configuration, low-level hardware interfaces, secure boot, PCIe, and high-speed networking. The engineer will collaborate closely with hardware, FPGA, security, manufacturing, and application teams to deliver a secure, reliable, production-ready appliance.\nResponsibilities\nEmbedded Linux Platform\nDevelop, maintain, and reproducibly build a Buildroot-based Linux distribution. \nCustomize and maintain Linux kernels for selected System-on-Modules (SoMs). \nConfigure and maintain device trees and board-specific platform definitions. \nBuild and maintain BSPs for custom HSM hardware and successive board revisions. \nIntegrate kernel drivers, platform services, bootloaders, and root filesystems. \nOptimize boot performance, system footprint, reliability, and maintainability. \nSupport production images, manufacturing configuration, and secure update mechanisms. \nHardware Integration\nBring platform hardware into Linux and expose clean, documented interfaces to application software. \nIntegrate and validate I²C, SPI, GPIO, UART, USB, PCIe, EEPROM/flash, and other board-level interfaces. \nEnable sensors, fan controllers, LEDs, buttons, watchdogs, voltage monitors, reset controls, TPMs, and secure elements. \nDevelop or adapt kernel drivers and user-space services where existing interfaces are insufficient. \nUse schematics, datasheets, oscilloscopes, logic analyzers, and other tools to diagnose board-level issues. \nSecurity\nDesign, implement, maintain, and validate secure boot and the complete chain of trust. \nConfigure and integrate hardware roots of trust, TPMs, secure elements, and measured-boot capabilities where appropriate. \nRecommend secure component choices and platform architectures based on threat, lifecycle, and supply-chain considerations. \nReview hardware and low-level software designs for security weaknesses and attack surface. \nSupport tamper detection, encrypted storage, key protection, secure manufacturing, and device provisioning. \nDefine and support secure firmware and software update strategies, including rollback protection and recovery. \nNetworking\nIntegrate and support 10 GbE connectivity through PCIe-connected network devices and external Ethernet interfaces. \nConfigure Ethernet controllers, PHYs, drivers, link behavior, and relevant hardware offload features. \nTune the Linux networking stack for throughput, latency, reliability, and predictable appliance behavior. \nDiagnose performance bottlenecks across PCIe, DMA, interrupts, drivers, and the network stack. \nPlatform Enablement\nLead bring-up of new SoMs, custom boards, and hardware revisions from first power-on through application readiness. \nCreate platform diagnostics, hardware validation utilities, and manufacturing test support. \nEstablish automated, repeatable build and integration workflows for embedded platform releases. \nSupport production, quality, field engineering, and sustaining activities throughout the product lifecycle. \nDocument platform architecture, interfaces, security assumptions, build procedures, and operational constraints. \nRequirements\nRequired Qualifications\nBachelor’s or Master’s degree in Computer Engineering, Electrical Engineering, Computer Science, or a related field, or equivalent practical experience. \nFive or more years of professional experience developing embedded Linux systems. \nStrong C programming and debugging skills in resource-constrained or hardware-adjacent environments. \nHands-on experience with Buildroot or Yocto, Linux kernel configuration, device trees, and cross-compilation toolchains. \nPractical knowledge of the Linux boot process, bootloaders such as U-Boot, root filesystems, kernel modules, and driver integration. \nExperience collaborating across hardware, systems, security, and application engineering disciplines. \nProficiency with Git and disciplined software configuration-management practices. \nRequired Technical Experience\nEmbedded Linux\nBuildroot or Yocto; Linux kernel configuration and customization; device trees; bootloaders; init systems; root filesystems; kernel modules; BSP and driver integration. \nHardware Interfaces\nHands-on experience with several of the following: I²C, SPI, UART, GPIO, PCIe, USB, MDIO, Ethernet PHYs, DMA, and interrupts. \nNetworking\nLinux networking stack, Ethernet drivers, 10 GbE, PCIe-connected networking, and network performance analysis or tuning. \nPlatform Security\nExperience with one or more of the following: secure boot, measured boot, TPMs, secure elements, trusted execution, hardware roots of trust, secure updates, or applied cryptography fundamentals. \nPreferred Qualifications\nExperience developing security appliances, HSMs, cryptographic products, or other high-assurance embedded systems. \nFamiliarity with FIPS 140-3, Common Criteria, or comparable product-security certification environments. \nARM64 platform experience and familiarity with SoMs from NXP, AMD, Intel, TI, or similar vendors. \nLinux kernel or PCIe driver development experience. \nExperience reviewing schematics and conducting hands-on hardware debugging. \nExperience with manufacturing diagnostics, secure provisioning, lifecycle controls, and field-update strategies. \nNice to Have\nOpenSSL, PKCS #11, secure key storage, or related cryptographic interfaces. \nTrusted Firmware-A, OP-TEE, trusted execution environments, or hardware-backed attestation. \nRust for systems programming. \nCI/CD practices for embedded systems and reproducible, containerized build environments. \nExperience with performance profiling, reliability testing, or fault-injection techniques. \nWhat Success Looks Like\nNew hardware platforms boot reliably and can be brought to application readiness through a repeatable, documented process. \nAll required peripherals and control signals are exposed through stable, well-documented Linux interfaces. \nSecure boot and the platform root of trust are implemented, validated, maintainable, and aligned with product-security goals. \n10 GbE and external Ethernet interfaces achieve expected throughput, latency, and reliability. \nBuilds are reproducible, version-controlled, automated, and suitable for manufacturing and field release. \nPlatform risks are identified early, communicated clearly, and addressed in partnership with hardware and security teams. \nThe embedded platform provides a stable, secure foundation that allows HSM application teams to deliver confidently. \nBenefits\n Health, dental, vision, life, and short/long-term disability insurance\n Paid vacation, holidays, and sick leave\n Competitive compensation and opportunities for advancement\n Retirement plan with employer contribution match\n Welcoming, family-style corporate culture uniquely suited to fast-paced, entrepreneurial, and motivated individuals\n One of San Antonio’s “Best Places to Work” for nine consecutive years","description_format":"text","description_chars":7399,"description_truncated":false,"requirements":{"experience_years_min":null,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":{"level":"bachelor","optional":false},"security_clearance":false,"languages":[]},"benefits":["Retirement
