• Leverage AI-assisted development practices and tools (Copilot, Cursor, Claude Code, and similar) to accelerate delivery without sacrificing quality.
• Run design reviews, give technical guidance, and help onboard the engineers who join after you.

Minimum Qualifications

• Experience: 5+ years of professional software engineering experience.
• Full Stack Depth: Production experience building and operating modern web applications across both front and back end. Expert-level proficiency in C# / .NET and a modern React-based framework (Next.js strongly preferred).
