Linux Systems Engineer
Embedded, IoT & Edge Infrastructure
DISCIPLINE: Embedded Linux
SENIORITY: Mid · Senior
EXPERIENCE: 3+ years
STACK FOCUS: Yocto · WebKit
01 About the role
We're looking for a Linux engineer with an investigative mindset and a solid foundation in embedded systems. 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
