Filtronic is seeking a highly skilled Embedded Software Engineer with strong expertise in embedded Linux, Yocto-based systems, RTOS development, and networking and secure communications. The Embedded Software Engineer will design and develop robust embedded Linux control platforms, networked control systems, and Zephyr- or bare-metal-based close-coupled subsystems. You will analyse existing product architectures, define and implement new software solutions, and help ensure reliable and secure communication across distributed processing elements. You will be a key part of a multidisciplinary team working on controllers and their subsystems, connected by CAN buses, networks, and serial interfaces. You are also likely to work on Yocto Linux within the controller systems. This includes designing and implementing communication protocols between FPGA devices, ARM Cortex-M real-time subsystems, and Cortex-A-based Linux environments such as STM32MP and AMD Zynq devices, ensuring reliable inter-processor communication across the full system architecture. Architecting, developing, and maintaining embedded Linux systems using Yocto. Supporting board bring-up, including diagnosis using oscilloscopes, logic analysers, and software-based debugging techniques. Designing and maintaining networking interfaces, including REST APIs, SNMP agents, and OpenAPI specifications. Implementing and debugging TCP/UDP communication layers, low-level networking behaviour, and protocol performance. Developing system services, daemons, device drivers, and communication middleware on embedded Linux. Leading troubleshooting and root-cause analysis for embedded networking and security issues. Defining embedded software requirements, interface specifications, and technical documentation. Working closely with hardware, FPGA, and systems engineers to ensure reliable and secure data and control flow. Bachelor’s degree in Computer Science, Electronic Engineering, or a related field, or equivalent practical experience in low-level embedded systems development. Strong professional experience in embedded Linux software development. Strong proficiency in C/C++ for embedded systems, including optimising CPU and RAM utilisation. Knowledge of digital communication interfaces such as Gigabit Ethernet, CAN, SPI, I2C, UART, and RS422. Strong debugging experience using oscilloscopes, logic analysers, and software debugging tools such as GDB, perf, and valgrind. Hands-on experience with the Yocto Project, PetaLinux, or similar build systems. Strong understanding of Linux kernel architecture, device drivers, bootloaders, systemd, and system services. Solid understanding of secure networking protocols such as TLS, SSH, IPSec, and as well as authentication and encryption methods. Solid proficiency in Python. Familiarity with MISRA C/C++ or other high-reliability embedded software standards. Experience in Linux systems automation, including CI/CD and testing. Basic soldering ability for minor modifications or attaching leads for probing. Ability to obtain SC security clearance, where required by the nature of the work.
