C# Sensor Software Engineer

We are seeking a Sensor Software Engineer to design, develop, and integrate sensor capabilities within a Marine Domain Awareness (MDA) platform. The role focuses on ingesting, controlling, and processing data from coastal surveillance cameras, radio direction finders (RDF), radar, AIS, and other maritime sensors, and exposing this data in a consistent, operationally robust format., You'll work on the "sensors at the fringe" fixed and mobile surveillance equipment such as radars, cameras, RDF, AIS, and other specialist maritime sensors. Your mission as a Sensor Software Engineer will be to integrate, calibrate, and optimise these systems in non-production environments, building the software that makes their outputs usable for downstream systems and training our Delivery Team for field deployment.

The role of Sensor Software Engineer spans multi-domain sensor fusion, AI-assisted analysis, anomaly detection, augmented reality, autonomous sentry operation, and evidence collection. You'll work closely with colleagues across software, hardware, data science, and infrastructure to bring innovative, high-performance edge solutions to life.

Sensor Integration & Control

• Develop integrations with maritime sensors including:

• Coastal surveillance cameras (e.g. PTZ, thermal, EO/IR)
• Radio Direction Finders (RDF)
• Radar and AIS data sources

• Implement control interfaces (e.g. PTZ, presets, tracking handoff)
• Work with proprietary and undocumented APIs where required

Backend Development (.NET)

• Build robust services using C# and .NET
• Develop APIs and services for downstream consumers
• Optimise for performance, reliability, and low-latency processing
• Work within distributed, containerised environments

System Integration

• Work across a distributed system (e.g. message brokers, microservices)
• Integrate with existing platform components and abstraction layers
• Support deployments in on-prem / air-gapped environments

The role of Sensor Software Engineer is a hands-on engineering role requiring strong C#/.NET development skills, experience working with real-world sensor systems, and the ability to partner effectively with AI/ML components to deliver intelligent detection, classification, and tracking capabilities., Core Engineering

• Strong experience in C# and .NET (Core / .NET 6+)
• Solid understanding of distributed systems and event-driven architectures, + Surveillance cameras (PTZ, ONVIF, RTSP, video streams)

• Radio systems or RDF
• Radar, AIS, or similar telemetry sources

• Comfortable working with hardware interfaces and imperfect APIs

Systems & Infrastructure

Experience with: *

• Messaging systems (e.g. RabbitMQ or similar)
• Containerisation (Docker)
• Linux-based deployments

• Understanding of performance, scaling, and resilience challenges

Desirable Experience

• Experience in maritime, defence, or surveillance domains
• Familiarity with video processing pipelines
• Experience working in air-gapped or high-security environments
