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 ownReverse 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 bringMUST NON-NEGOTIABLE3+ 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 SIGNALWebKit 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 forThinks 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 forAPPLYProcess run by a specialized technical consultancy. ● Candidates evaluated by engineers real conversations, real hardware. ●.
