Role Description:
At Meshnet Electronics we're building a 5G connectivity hub on embedded Linux from the ground up for board bring-up to shipping firmware. You'll own core firmware and low-level software for the platform, working closely with hardware and product from the very first prototype. Once the hub ships, you'll help extend the same expertise to an Android-based mobile device, so this is a long-term role with a growing scope.

What You'll Do:
Bring up current hardware: bootloader (U-Boot), kernel, and board support packages on ARM SoCs
Build and maintain a custom Linux distribution using Yocto / OpenEmbedded (or Buildroot)
Write and debug Linux device drivers and kernel modules (I2C, SPI, UART, USB, PCIe, GPIO)
Integrate and validate 5G/LTE modems and cellular connectivity stacks (QMI/MBIM, Modem Manager, RIL)
Develop networking and hub features: routing, Wi-Fi, firewall, OTA update, and device management
Optimize for performance, power, thermal, and boot time on constrained hardware
Debug at the hardware level using JTAG, oscilloscopes, logic analyzers, and serial consoles




Own the firmware release process: CI, versioning, secure boot, and OTA delivery
Later: contribute to Android platform / HAL / BSP work for a companion mobile device
Qualifications
5+ years in embedded firmware / embedded Linux development
Strong C (and ideally C++); comfortable in a Linux userspace + kernel environment
Hands-on board bring-up experience on ARM (Cortex-A) SoCs
Linux device driver development and kernel debugging
Build systems: Yocto/OpenEmbedded or Buildroot
Bootloader experience (U-Boot) and understanding of the Linux boot flow
Solid grasp of networking fundamentals (TCP/IP, routing, DHCP, NAT)
Comfortable reading schematics and datasheets, and debugging with hardware tools
Applied knowledge of Electrical Engineering concepts relevant to embedded system design and hardware-software integration.
Advanced Debugging skills for diagnosing and resolving issues across firmware, har
