Responsibilities Design, build, test, and maintain production software using C#, WPF, and .NET, with a focus on reliability, security, performance, and maintainability. Contribute to technical design and architecture, including evaluating tradeoffs, defining interfaces and patterns, and documenting decisions. Deliver product capabilities from requirements and estimation through implementation, code review, automated testing, deployment support, and post-release evaluation. Diagnose and resolve complex defects and production issues involving application code, services, integrations, data flows, and Windows endpoint environments. Maintain engineering quality through testable code, code reviews, automated testing, observability, secure development practices, and disciplined source control. Collaborate with and mentor engineers through design reviews, technical discussions, and problem solving. Use AI-assisted engineering workflows to improve development efficiency while maintaining security, governance, code quality, and release reliability. Qualifications 7+ years of professional software development experience, including substantial hands-on experience with C#, WPF, and .NET production applications. Direct experience building Windows deployment or application deployment software. Hands-on experience configuring and troubleshooting network services, including DHCP, PXE, proxy servers, and CDNs.
