The posting

Smart Design is searching for a freelance embedded Linux platform engineer to join us for an exciting client project.

We build x86-based Linux devices for the field. You'll own the platform layer, from firmware power-on to a locked-down, encrypted system, plus the kernel and device integration underneath our applications.

What you'll do

  • Maintain the x86 secure boot chain (UEFI, shim, bootloader, signed kernels and modules)
  • Implement full disk encryption with TPM2-based unlocking and recovery
  • Configure, patch, and compile custom Linux kernels
  • Write and maintain kernel modules for custom hardware
  • Integrate USB devices across classes, and write udev rules for naming, permissions, and hotplug

Required qualifications

  • UEFI secure boot on x86, including key management and module signing
  • Full disk encryption on Linux (LUKS2, ideally with TPM2)
  • Solid understanding of the x86/UEFI boot process
  • USB protocol and device classes (HID, CDC, UVC, UAC, mass storage)
  • udev rules
  • Kernel module development and kernel compilation
  • Strong C, plus Bash and Python

Nice to have

  • Hardware debugging tools (logic analyzers, USB analyzers)
  • Yocto or Buildroot
  • USB gadget mode

The role will be full-time, in a hybrid capacity, with ability to be onsite in our Brooklyn studio at least every other week.

Hourly rate dependent on years of experience, $100 up to $130/hour.

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
