Write clean, efficient, maintainable C# code and promote best engineering practices through example.
Lead and maintain architectural consistency across all Clean Architecture layers (Domain, Application, Infrastructure, UI).
Ensure adherence to system-wide architectural principles and promote scalable, testable designs.
Design and implement features using a Redux-based architecture (Redux.NET), including actions, reducers, effects, and immutable typed state.
Build and maintain state-machine–driven workflows (Stateless) supporting long-running operations, retries, timeouts, and error-handling mechanisms within a self-hosted Windows service.
Develop and optimize Blazor (Server and/or WebAssembly) components with a focus on performance, lifecycle management, thread-safety, and minimal re-rendering.
Implement robust UI patterns, including forms, routing, JS interop, virtualization, and rendering optimization.
Maintain comprehensive and up-to-date technical documentation, including architectural diagrams, state diagrams, data contracts, and deployment processes.
Communicate effectively with non-technical stakeholders, translating complex technical concepts into clear, understandable language.
Provide regular updates on technical risks, progress, and system considerations.
Ensure high code quality through automated testing frameworks, including unit tests, reducers/effects tests, and bUnit component tests.
Troubleshoot complex issues efficiently and drive continuous improvement across the engineering lifecycle.
Stay informed on emerging technologies, frameworks, and industry best practices.
Share insights with the team and advocate for appropriate adoption of new tools and methodologies.
About you

Advanced proficiency in C#/.NET, including modern asynchronous programming (async/await, CancellationToken, IAsyncEnumerable, thread-safety patterns).
Strong experience designing and implementing Clean Architecture across domain, application, infrastructure, and UI layers.
Deep expertise with Blazor (Server and/or WebAssembly), including lifecycle behavior, rendering pipeline, diffing, virtualization, forms, routing, JS interop, and performance tuning.
Practical hands-on experience with Redux.NET, including actions, reducers, effects, side effects, and associated testing patterns.
Experience building complex workflows using Stateless with triggers, guards, retries, timeouts, and deterministic testability.
Strong background in ASP.NET Core APIs, background services, streaming endpoints, and device-facing communication protocols (gRPC, SignalR, WebSockets, USB/serial/CAN).
Solid understanding of concurrency and thread-safety tools such as SemaphoreSlim, AsyncLock, ReaderWriterLockSlim, lock-free structures, and Blazor UI-thread constraints.
Experience developing SPA-style front-end applications.
Strong test automation skills using frameworks such as xUnit, NUnit, Moq.
Additionally, experience with the following would be a plus:
Scrum methodologies and globally-distributed teams
.NET Core 8.0
Multi-threaded C# development
Offline-first Blazor WebAssembly, background sync
Event-sourcing or audit-friendly state persistence
Knowledge of JSON and REST based services
GIT/Azure DevOps workflow
Knowledge of Design Patterns
