Job description
- Design and maintain the software architecture of the VCS desktop application built in C# 14 / .NET 10 and WPF using the MWM pattern (XAML), targeting real-time system responsiveness (<1ms).
- Develop and integrate Windows Service components for background processing, system monitoring and service lifecycle management.
- Build real-time data visualisation and charting (ScottPlot WPF) for live instrumentation telemetry at 4Hz+ sample rates, using Material Design Themes for consistent UI styling.
- Develop batched 1/0 logging, structured logging/telemetry and compliance/certification report generation.
- Manage encrypted local storage using SQLite and SQLite Cipher for configuration, calibration and operational data.
- Networking & Communication
- Develop and optimise high-throughput, low-latency UDP/TCP networking for simultaneous real-time communication with up to 240 loadbank controllers.
- Implement multicast and unicast packet handling across IPv4 and IPv6 networks, including asynchronous simultaneous dataframe processing.
- Design and maintain failover and degraded-mode behaviour to ensure system resilience under adverse network conditions.
- Design and maintain real-time data pipelines with a focus on algorithmic complexity optimisation, fault tolerance and graceful degradation.
- Perform profiling and optimisation using Visual Studio 2026, dotMemory (memory profiling), dotTrace (CPU/event profiling) and Wireshark (network packet inspection).
- Participate in code reviews and PR workflows following trunk-based development with semantic versioning.
- Apply SOLID principles, Clean Architecture and established design patterns (MWM, Factory, Observer, Strategy, Decorator, Dependency Injection) throughout the codebase.
Requirements
- Degree in Software Engineering, Computer Science, or equivalent professional experience.
- Strong professional experience developing desktop applications in C# / .NET (6+), including WPF with MWM architecture.
- Demonstrable expertise in real-time or high-throughput network programming: UDP/TCP sockets, asynchronous 1/0, multicast/unicast, concurrent data processing.
- Understanding of SOLID principles, Clean Architecture, Dependency Injection and common design patterns (Factory, Observer, Strategy, Decorator).
- Experience with performance profiling and optimisation of .NET applications (memory, CPU, network).
- Proficiency with Git in a trunk-based development workflow using semantic versioning.
- Experience with unit testing frameworks (xUnit/NUnit), TDD practices and code coverage tooling.
- Knowledge of industrial communication protocols (Modbus/TCP, serial RS232/422/485) is highly desirable.
- Familiarity with Windows Service development, SQLite, encrypted storage and Windows Installer technologies is a plus.
- Strong problem-solving skills, collaborative mindset and clear technical communication.
- Ability to read and interpret electrical/mechanical drawings is a plus.
