About Flexxon & X-PHY®

Flexxon is a global pioneer in hardware-level security innovations. Our flagship solution, X-PHY®, is the world’s first AI-embedded cybersecurity solution operating directly at the firmware and physical layer of the OSI model.

We don’t just build products—we build the future. As a cybersecurity technology company, we are redefining industry standards, pushing boundaries, and creating transformative solutions to protect the digital world.

To support the continued development of our hardware and firmware-based cybersecurity technologies, we are looking for a Firmware Engineer to join our R&D team.

In this role, you will develop low-level embedded software, Embedded Linux board support packages (BSP), and application-level software for custom hardware platforms. The ideal candidate brings strong C/C++ programming skills, proficiency in Python and Shell scripting for automation, and practical Embedded Linux experience. Prior exposure to FPGA architectures or the AMD Xilinx ecosystem is highly advantageous.

Key Responsibilities:

Firmware & Embedded Software: Develop, debug, and maintain low-level firmware and system software using C and C++.

Embedded Linux & BSP Development: Develop and customize Embedded Linux Board Support Packages (BSP), device drivers, bootloaders (U-Boot), and kernel configurations.

Application & SDK Development: Implement user-space applications and SDKs on customized Embedded Linux boards using C and C++.

Automation & Scripting: Write test automation scripts, build utilities, and workflow tools using Python and Shell scripting.

Hardware Bring-Up & Debugging: Participate in initial board bring-up and debug hardware-software interactions utilizing hardware comprehension and standard lab tools.

FPGA & System Acceleration Integration: Collaborate on hardware/software co-design for SoC/FPGA platforms, integrating custom IP cores, PetaLinux configurations, and acceleration frameworks.

Code Quality & Documentation: Participate in peer code reviews, support quality code practices, and maintain precise technical documentation.

Requirements

Education: Bachelor’s degree in Electrical Engineering, Computer Engineering, Computer Science, or a related field.

Core Programming: Hands-on experience in low-level firmware and software development using C and C++.

Scripting Languages: Proficiency in Python and Shell (Bash/Sh) scripting for build automation and hardware testing.

Embedded Linux & BSP: Experience with Embedded Linux development, BSP customization, device drivers, and device trees using build tools such as Yocto or Buildroot.

Application Development: Proven track record in developing user-space applications and SDKs for customized Embedded Linux targets in C/C++.

Hardware Comprehension: Good understanding of hardware fundamentals, SoC architectures, board bring-up processes, and common communication interfaces (SPI, I2C, UART, PCIe, Ethernet).

Preferred Qualifications

AMD Xilinx Ecosystem: Hands-on experience with AMD Xilinx Zynq UltraScale+ MPSoC (ZynqMP) chips, Vivado Design Suite, PetaLinux, and the Vitis Unified Software Platform.

Edge AI Integration: Familiarity with the AMD Xilinx Vitis AI platform for deploying machine learning models on target hardware.

Embedded Security & Networking: Good understanding of Root of Trust (RoT) security concepts, secure boot mechanisms, and embedded network protocols.

Build Systems & CI/CD: Experience with Git, CMake, Docker, and CI/CD automation pipelines.
