C# Code Quality Assurance Lead

The work

As a C# Quality Assurance Lead, you will review AI-generated code and trainer QA work against project guidelines. You will assess correctness, runtime behavior, type safety, async behavior, debugging accuracy, readability, maintainability, performance, security, test coverage, and instruction following.

You will also support contributors, improve review processes, and help keep quality standards consistent across C# training projects.

• Review C# code, .NET snippets, API examples, debugging responses, tests, architecture explanations, and step-by-step reasoning.
• Find incorrect logic, code that will not run, flawed async usage, weak error handling, type-safety problems, security risks, invented APIs, and incomplete explanations.
• Escalate recurring or serious quality issues and answer questions about .NET behavior, async/await, LINQ, dependency injection, EF Core, testing, security, and rubric interpretation.
• Create and maintain style guides, trackers, FAQs, examples, honeypots, calibration tasks, and onboarding materials.
• Lead onboarding and training calls for C# contributors and help improve QA workflows.
• Communicate with and support remote trainers, reviewers, engineers, coding mentors, or QA contributors.
