Job description
Our client, a prominent player in the Defence & Security sector, is currently seeking a skilled Software Engineer C++ for a contract role in Stevenage, Hertfordshire. This position involves working 100% on-site, developing and maintaining software in a Linux environment. You will engage with high-speed real-time data flows, and complex multi-threaded processing pipelines.
Key Responsibilities:

• Designing and developing real-time test and capture software on Linux systems using C++
• Integrating and interfacing with high-speed SFPDP cards across multi-channel data pipelines
• Architecting and implementing robust, scalable, and maintainable multi-threaded applications
• Defining and implementing data sequencing and synchronisation logic for deterministic capture and replay
• Working with hardware teams to ensure seamless integration and timing alignment
• Leading and contributing to system integration, verification, and testing at both component and system levels
• Conducting performance analysis, debugging, and optimisation of real-time systems
• Documenting architecture, interface definitions, and test procedures

Job Requirements:

• Extensive experience in C++ development in a Linux environment
• Proficiency in C# for tooling, test interfaces, or Windows components
• Experience working with real-time data systems, particularly involving SFPDP or other high-speed digital protocols
• Demonstrable skills in multi-threaded and concurrent programming
• Experience with low-level I/O, DMA, or driver-level interactions with PCIe cards
• Familiarity with software sequencing frameworks or custom state machines
• Strong experience with integration, system test, and debugging complex interactions between software and hardware
• Understanding of software design principles, memory management, and performance optimisation
• Experience with version control systems (e.g., Git) and CI/CD pipelines

Desirable Skills:

• Experience with SFPDP specifically in defence, aerospace, or data acquisition contexts
• Knowledge of FPGA-based data acquisition systems and synchronisation methods
• Familiarity with unit testing frameworks, automated test rigs, or hardware-in-the-loop setups
• Experience developing or integrating with real-time operating systems (RTOS) or using real-time Linux extensions

If you are an experienced Software Engineer proficient in C++ and ready to contribute to mission-critical systems within the Defence & Security sector, apply now to join our client's highly dedicated and innovative team in Stevenage.
