What we're looking for from you:

We are currently looking to recruit an experienced self‑starting Software Engineer for a position in Stevenage, Hertfordshire. The role is 100% on site. The successful candidate will join our development team responsible for building and integrating real‑time test and data capture systems. The role will focus on developing and maintaining software in a Linux environment, working closely with high‑speed multi‑channel SFPDP cards, real‑time data flows, and complex multi‑threaded processing pipelines. Proficient in C++ and with knowledge of C#, you will play a critical part in the design, development, integration, and verification of test software solutions that are central to our system validation and delivery capabilities.

Responsibilities:

• Design and develop real‑time test and capture software on Linux systems using C++.
• Integrate and interface with high‑speed SFPDP cards across multi‑channel data pipelines.
• Architect and implement robust, scalable, and maintainable multi‑threaded applications.
• Define and implement data sequencing and synchronisation logic to support deterministic capture and replay.
• Work with hardware teams to ensure seamless integration and timing alignment between software and capture cards.
• Lead and contribute to system integration, verification, and testing at both component and system levels.
• Conduct performance analysis, debugging, and optimisation of real‑time systems.
• Document architecture, interface definitions, and test procedures to support handover and formal test activities.

Skillset / experience required:

• Experience in C++ development in a Linux environment.
• Proficiency in C# for tooling, test interfaces, or Windows components as needed.
• Proven experience working with real‑time data systems, preferably 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 or similar.
• Familiarity with software sequencing frameworks or custom state machines for test execution.
• Strong experience with integration, system test, and debugging complex interactions between software and hardware.
• Strong 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 (Serial Front Panel Data Port) 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 (HWIL) setups.
• Experience developing or integrating with real‑time operating systems (RTOS) or using real‑time Linux extensions.
• Experience developing using LabVIEW suite of packages would be an advantage.
