• Partner with architects, product owners, developers, and adjacent technology teams to convert business capabilities into high-quality technical solutions.
• Use GenAI coding assistants to accelerate implementation, refactoring, unit testing, regression support, code reviews, scripting, automation, troubleshooting, and documentation while maintaining ownership for correctness and quality.
• Apply agentic workflows, prompt engineering, custom instructions, and spec-driven development practices to improve developer productivity and team execution.
• Drive engineering quality through automated testing, code review discipline, performance analysis, observability, resiliency design, and production readiness practices.
• Support modernization initiatives by moving legacy capabilities toward distributed .NET services, cloud-native platforms, event-driven architecture, and modern data stores.
• Guide and collaborate with engineers in a team-oriented environment while establishing repeatable practices for effective and responsible AI-assisted development.

Required Qualifications

• Bachelor s degree in Computer Science, Software Engineering, or related technical field, or equivalent practical experience.
• 7+ years of professional software engineering experience developing scalable, high-performance .NET, cloud-based, and web services applications that support high-volume transactions in highly available environments.
