• At least 10 years of professional software engineering delivering large, complex applications end-to-end.
• Senior-level proficiency with .NET, C#, ASP.NET Core, EF Core, React/TypeScript, Blazor, SQL Server, and desktop technologies (WPF, WinUI 3, .NET MAUI, Blazor Hybrid).
• Experience maturing SDLC and engineering standards and managing external consultancies.

• Experience with Microsoft Azure services and cloud architecture patterns, Infrastructure as Code, CI/CD pipelines, automated testing, and SDLC discipline.
• Strong communication skills, problem-solving mindset, ownership, and ability to mentor and hold partners accountable to quality standards.

Responsibilities

• Design, build, and deliver full-stack applications using .NET (including .NET 8/10), C#, ASP.NET Core, Entity Framework Core; web front-ends, desktop/fat-client apps, Web APIs, and data layers.
• Build responsive web UIs with React/TypeScript and/or Blazor; develop modern Windows desktop clients (WPF, WinUI 3, .NET MAUI, Blazor Hybrid) backed by SQL Server.
• Own architecture from discovery through release, balancing scalability, performance, security, and maintainability.
• Integrate AI-assisted/agentic coding tools (Claude Code, GitHub Copilot, OpenAI Codex), set team norms, and review standards for AI-generated code.
• Evaluate AI tooling landscape and recommend changes to the AI development roadmap.
• Establish and mature SDLC practices: source control, branching, PR/code review, CI/CD, testing, and release/change management.
• Define and document engineering standards, solution patterns, and reference architectures.
• Act as a hands-on technical lead: facilitate discovery sessions, review pull requests, coordinate releases, and mentor developers and analysts.
