The Opportunity

Are you a versatile Software Engineer who excels at the intersection of high-performance backend logic and intuitive user interfaces?

We are seeking a high-calibre GUI Software Engineer to join a world-class engineering team at the forefront of UK defence innovation. Working within a pioneering technology consultancy, you will play a pivotal role in evolving an advanced Electronic Warfare (EW) suite.

This is not "standard" application development. You will be building sophisticated interfaces that visualise complex data from Array Processing, Communications, and Sensor domains, ensuring mission-critical information is delivered with precision and speed.

The Role

As a GUI Software Engineer, you will bridge the gap between complex signal processing and the end-user experience. You will:

• Architect & Implement: Design efficient, real-time systems that handle high-throughput data.
• Innovate: Apply emerging technologies to keep the Electronic Warfare suite at the cutting edge of the industry.
• Collaborate: Work across diverse projects involving Software Defined Radio (SDR) and advanced communications.
• End-to-End Delivery: Develop new features from concept to deployment, ensuring robust unit and system testing throughout.

Your Technical Profile

To be successful in this role, you will need a dual-strength background in both UI and systems-level programming:

The Essentials:

• C# Expertise: Deep experience in User Interface development and associated backend services.
• C++ Proficiency: Strong skills in C++ for services and Digital Signal Processing (DSP).
• DevOps Mindset: Proven experience with modern version control (Git) and CI/CD pipelines.
• Testing: A rigorous approach to unit and system testing.
• Clearance: You must hold current SC Clearance to be considered for this role.

The "Value Add" (Desirable):

• Experience building UIs for scientific or technical applications.
• Expertise in WPF for Windows-based interfaces.
• Familiarity with SQL databases.
• Knowledge of modern communication protocols (REST, WebSockets).
• An interest in or experience with Software Defined Radio (SDR) platforms.
