✨ Why This Is a Good Vibe Coding Job
This role is a 'vibe coding' dream because it explicitly lists the practice as a core engineering standard rather than a side tool. You will be architecting a greenfield enterprise system where high-level prompting and human-in-the-loop debugging are the primary methods for driving productivity and innovation.

You won't just be using AI tools; you'll be architecting the very workflows that define how the next generation of software is built.

Because CoStar is prioritizing 'vibe coding' and AI-assisted engineering, you will have the freedom to leverage advanced code generation, automated testing, and agentic workflows to deliver high-performance microservices. This is an opportunity to prove that natural-language-driven development can scale to support millions of real estate data points.
