• Develop primarily in C# using .NET for Linux (e.g., .NET Core/.NET 8+) for system utilities and agent components.
• Frequent use of C++ for low-level system interactions is not feasible in C#, specifically for performance-critical and Linux-specific components.
• Take responsibility for carrying work from inception through design, implementation, testing, and delivery across the full software development lifecycle.
• Collaborate with backend and other enterprise teams to design, integrate, and deliver robust solution designs.
• Translate business requirements and user scenarios into technical specifications, user stories, and tasks.

• Passionate about AI-driven development.
• Experience writing and maintaining unit tests, automation tests, and integration tests.
