SRT Marine Systems plc
(

The Edge Team is responsible for developing the next-generation hardware and software platform that forms the outer layer ("edge") of our wider Maritime Domain Awareness (MDA) system. This platform consolidates and analyses sensor data gathered from the maritime environment, enhancing the intelligence available to users at remote command and control centres.

Our systems operate at the intersection of edge computing, sensor fusion, AI-assisted analysis, and autonomous operation, delivering real-time maritime situational awareness and actionable intelligence.

About the Role

We are seeking a Senior C# Software Developer to help port and extend an existing proof-of-concept (PoC) system written in VB.NET. The system performs vessel detection and tracking by combining ("fusing") AIS and radar data sources.

What You'll Be Doing

You will play a key role in transforming this PoC into a robust, scalable, production-grade edge platform—supporting multi-domain sensor fusion, AI-assisted anomaly detection, augmented reality visualization, autonomous "sentry" operations, and incident evidence capture.

What You'll Bring

  • Strong proficiency in C#, with experience developing robust, high-performance applications.
  • Background in C++, with a solid understanding of software fundamentals such as memory management, concurrency, and performance optimization.
  • Demonstrable experience in at least one of the following domains:
  • Sensor data processing (radar, AIS, optical, or RF)
  • Tracking systems or sensor fusion algorithms
  • Real-time or embedded systems
  • Understanding of networking protocols and data serialization (e.g., TCP/UDP, JSON, Protobuf).
  • Familiarity with multi-threaded and asynchronous programming patterns.
  • Ability to work effectively within an interdisciplinary engineering team.

Innovation
– Driving improvement through creativity and forward-thinking.

Quality

Why Join Us?

  • Make a direct impact on global maritime safety and sustainability.
  • Enjoy flexible hybrid working.

Competitive salary and benefits, including:

  • Matched pension contributions up to 5%
  • 25 days annual leave (rising to 28 with service)
