- Perform code reviews, troubleshoot complex issues, and occasionally write production code to unblock teams.
Quality, Risk, and Governance- Establish quality gates, testing strategies (unit/integration/load), and reliability practices.
- Identify technical risks early and lead mitigation plans; ensure compliance and security best practices.
- Measure outcomes and iterate: track KPIs, gather feedback, and refine solutions over time.
Required QualificationsTechnical Depth (.NET Stack)- 10+ years of professional software development, with 6+ years focused on .NET.
- Expert-level C# and deep knowledge of .NET frameworks: ASP.NET Core, EF Core, Web APIs, background services, gRPC as needed.

- Demonstrated ability to make sound technology choices and justify them to both engineers and business stakeholders.
Client-Facing & Leadership- Proven track record leading client engagements and delivering complex projects on time and within scope.
