Linux Systems Engineer

Linux Systems Engineer - Detalhes da Vaga. ● Short term: take hardware from third-party signage vendors, understand what''s running on it, adapt our player to run reliably on top. ● Longer term: build our own Yocto-based image from scratch you''ll be shaping that foundation too. ● 02 What you''ll own Reverse engineer OS images from signage vendors boot, drivers, app stack. ● Port our signage player across hardware targets (ARM, x86). ● Integrate OTA frameworks SWUpdate, RAUC, A/B partition schemes. ● Build embedded Linux images (Yocto/OE) as we move to our own OS. ● Tune GPU drivers for smooth video and graphics on signage hardware. ● WebKit-based rendering (WPE WebKit, WebKitGTK) as primary runtime. ● Document ndings BSP quirks, BIOS/UEFI behavior, integration procedures. ● Partner with the app team on player requirements and OS constraints. ● 03 What you bring MUST NON-NEGOTIABLE 3+ years with embedded or edge Linux. ● Linux boot process BIOS/UEFI, U-Boot/GRUB, initrd, device tree. ● Yocto or Buildroot. ● OTA / update frameworks SWUpdate, RAUC, A/B partitions. ● GPU driver integration Mesa, Intel, AMD, ARM Mali/Vivante. ● Reverse engineering mindset analyze and document an unfamiliar OS image. ● Shell, C/C++, Git. ● Comfortable with real hardware, not just VMs. ● NICE BONUS SIGNAL WebKit on embedded WPE WebKit, WebKitGTK. ● Wayland / DRM-KMS display stack. ● Commercial signage hardware LG webOS, Samsung Tizen, BrightSign. ● Docker, CI/CD pipelines. ● Firmware analysis binwalk, Ghidra. ● Rust or Python. ● Networking bridge, vlan, iptables, mDNS. ● Security hardening / secure boot. ● 04 The kind of engineer this work asks for Thinks like an investigator. ● Given an unknown device, knows where to pull threads. ● Documents findings, not just fixes. ● Leaves a trail for the team. ● Comfortable with ambiguity. ● At ease with projects still taking shape. ● Likes making things run cleanly. ●On hardware they weren''t designed for APPLY Process run by a specialized technical consultancy. ● Candidates evaluated by engineers real conversations, real hardware. ● .
