Description

We are looking for a highly skilled Embedded Linux Engineer with strong expertise in Yocto, Linux kernel debugging, and secure system design. You will work on custom hardware platforms, often in early prototype stages, bringing up boards, debugging hardware/software interaction issues, and designing secure, production-ready Linux systems. This is a hands-on, low-level engineering role. You must be comfortable working close to hardware, reading schematics, debugging partially working prototypes, and implementing secure embedded architectures. Key Responsibilities Embedded Linux & Yocto Design and maintain custom Linux distributions using Yocto / OpenEmbedded Create and maintain custom layers, recipes, and BSPs Configure and customize U-Boot, Linux kernel, and root filesystem Optimize boot time and system stability Integrate OTA update mechanisms when required Kernel & Driver Development Debug, adapt, and extend Linux kernel drivers Work with I2C, SPI, UART, and similar on-board protocols Modify and debug device trees Analyze kernel logs, crashes, race conditions, and performance issues Investigate low-level timing and hardware interaction problems Hardware Bring-Up & Debugging Bring up partially working or prototype hardware Debug low-level issues using oscilloscopes, logic analyzers, and JTAG/debug probes Read and understand electronic schematics Distinguish hardware issues from software issues Collaborate closely with electronics and RF engineers Security & Networking Design and implement secure embedded Linux systems Implement and debug secure boot chains and bootloader hardening Implement dm-verity, read-only root filesystems, and disk encryption when required Configure secure remote access (VPNs, SSH hardening, firewall rules) Understand common network protocols Identify and mitigate system-level security risks Wireless & Communication Support integration of wireless subsystems (e.g., WiFi and proprietary RF solutions) Be familiar with wireless protocol specifications Possess sufficient RF fundamentals to collaborate effectively with RF engineers Debug integration issues across Linux, FPGA, and RF subsystems Strong experience with Embedded Linux Deep hands-on experience with Yocto / OpenEmbedded Solid working knowledge of C and ability to read/debug C++ Experience debugging and modifying Linux kernel drivers Strong device tree knowledge Experience securing embedded systems (secure boot, dm-verity, system hardening) Understanding of networking fundamentals and VPN-based architectures Working knowledge of Python (automation, debugging tools) Structured and methodical problem-solving mindset Comfortable working with non-final hardware Skills & Abilities Required Strong analytical thinker Calm and effective when debugging complex systems Able to work independently on ambiguous technical problems Comfortable in a lab environment Security-minded by default Clear communicator across disciplines Ownership mindset Nice to Have SDR (Software Defined Radio) knowledge MESH networking knowledge RF system familiarity Experience with high-throughput or real-time systems Experience with custom FPGA-integrated systems Experience with Xilinx FPGA platforms Experience performing security audits or threat modeling

Responsibilities

The role involves designing and maintaining custom Linux distributions using Yocto/OpenEmbedded, including BSPs, kernel customization, and boot time optimization. Key tasks also include debugging low-level hardware/software interactions, developing kernel drivers, and implementing secure embedded architectures like secure boot chains.
