Requirements
  • At least 5 years of experience developing in C, with deep familiarity with Linux kernel internals.
  • Proven experience writing and debugging Linux device drivers and kernel modules.
  • Solid understanding of kernel subsystems, including memory management, scheduling, filesystems, and networking.
  • Solid understanding of the Linux boot process and bootloaders.
  • Solid understanding of concurrency, locking, and interrupt handling in kernel space.
  • Experience with embedded Linux build systems such as Yocto or Buildroot.
  • Comfort working directly with hardware during bring-up and debugging with JTAG, oscilloscopes, or logic analyzers.
  • Strong debugging skills using tools such as gdb, ftrace, perf, kgdb, or crash dump analysis.
  • Ability to work independently and take ownership in a lean startup environment.
  • Work authorization for the location of the role is required.
  • Flexibility to occasionally work extended hours or weekends during critical periods is expected.
Responsibilities
  • Design, develop, and maintain Linux kernel code, including drivers, subsystems, and kernel modules.
  • Port, configure, and optimize the Linux kernel for custom hardware platforms.
  • Write and maintain device drivers for interfaces including I2C, SPI, UART, USB, PCIe, and Ethernet.
  • Debug and resolve kernel panics, race conditions, memory issues, and other low-level system failures.
  • Profile and optimize kernel and driver performance, including boot time, latency, and power consumption.
  • Work with bootloaders such as U-Boot and perform board bring-up for new hardware revisions.
  • Collaborate with hardware engineers during board bring-up and hardware/software integration.
  • Upstream patches where appropriate and track relevant upstream kernel changes and CVEs.
  • Contribute to kernel configuration, build systems such as Yocto and Buildroot, and continuous integration.
  • Document kernel architecture decisions, driver interfaces, and debugging procedures in a practical and reusable manner.
Desired Qualifications
  • Upstream Linux kernel contribution experience.
  • Experience with real-time Linux, including PREEMPT_RT, or other real-time operating systems.
  • Familiarity with security-hardening practices for embedded Linux, including secure boot and kernel hardening.
  • Experience with version control systems such as Git and kernel patch workflows, including mailing lists and git send-email.
  • Exposure to multiple CPU architectures, including ARM, RISC-V, and x86.
  • Experience with continuous integration and continuous delivery pipelines for embedded or system-level software.
  • Direct experience with low Earth orbit satellite component development, design, and in-orbit activities.

Simplify's Take

What believers are saying

  • Arlington approved E-Space’s 30-year lease, signaling unusually strong local government backing.
  • Beyon and e& partnerships validate satellite IoT demand across Bahrain and Gulf operators.
  • The company’s sustainability pitch matches rising enterprise demand for cheaper, lower-impact connectivity.

What critics are saying

  • Arlington’s Spring 2027 build depends on $115 million public spending and strict hiring milestones.
  • E-Space disclosed only $50 million funding, far below its massive constellation ambitions.
  • If Arlington slips or capital dries up, E-Space becomes a perpetual concept company.

What makes E-Space unique

  • Greg Wyler’s patented LEO design targets zero-trust, gateway-free satellite networking.
  • CommAgility integration gives E-Space 5G NTN source code and payload development depth.
  • Arlington’s 2025 headquarters plan ties manufacturing, hangars, and satellite R&D together.
