Job description

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.

• 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.

• Self-Managed, Ownership-Driven Culture that empowers individuals to take initiative and make an impact
  
• Performance-Based Bonuses that reward results, contributions, and value creation
  
• Passionate, Energetic, and Innovative Work Culture where ideas are encouraged and collaboration thrives
  
• Positive and Supportive Work Environment that values respect, teamwork, and high performance
