Senior Embedded Linux Engineer

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.

• Design and maintain custom Linux distributions using Yocto / Open Embedded
• Create and maintain custom layers, recipes, and BSPs
• Configure and customize U‑Boot, Linux kernel, and root file system
• Optimize boot time and system stability
• Integrate OTA update mechanisms when required

• 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

• 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

• Design and implement secure embedded Linux systems
• Implement and debug secure boot chains and boot loader hardening
• Implement dm‑verity, read‑only root file systems, 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

• 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 / Open Embedded
• 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

• 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

• 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
