* Bridge hardware control, data acquisition, and inspection analysis workflows into a cohesive user experience for NDT technicians.
Primary Responsibilities
Desktop Application Development (65%)
* Design, develop, and maintain the Avalonia-based desktop application for PAUT hardware control, data acquisition, and inspection analysis.
* Implement MVVM architecture with data binding, commands, and reactive UI patterns for industrial real-time applications.
* Build data visualization components using OxyPlot and custom controls for ultrasonic waveform display and analysis.
* Integrate with C++ signal processing engine via IPC/RPC mechanisms for realtime data exchange.
* Develop cross-platform deployment solutions targeting Windows, Linux, and WASM environments.
* Write comprehensive unit and integration tests to ensure robust, reliable application functionality.
* Optimize UI performance for real-time data visualization and hardware control responsiveness.
Technical Architecture & Integration (15%)
* Design and oversee desktop application architecture following MVVM patterns and separation of concerns.
* Collaborate on integration contracts with C++ signal processing engine and cloud backend APIs.
* Guide technical decisions on state management, data flow, hardware communication, and UI responsiveness.
* Ensure cross-platform compatibility and consistent behavior across Windows and Linux deployments.
* Coordinate with Web Team Lead on shared data models, APIs, and authentication flows.
Team Leadership & Mentorship (15%)
* Provide technical guidance and mentorship to mid-level and junior developers on desktop application development.
* Conduct code reviews ensuring quality, consistency, and adherence to MVVM and C# best practices.
* Foster knowledge sharing on Avalonia, industrial UI/UX patterns, and hardware integration techniques.
* Help team members debug complex issues spanning UI, hardware communication, and real-time data handling.
* Build team capability in cross-platform development and industrial software engineering.
Process & Documentation (5%)
* Address significant documentation debt by creating and maintaining technical documentation for application architecture, UI components, and workflows.
* Document hardware integration patterns, IPC protocols, and deployment procedures.
* Collaborate with Software Lead on sprint planning, story refinement, and technical feasibility assessments.
* Identify and communicate technical risks, dependencies, and blockers to Software Lead.
* Establish documentation standards and practices for the desktop application team.
