Why This Is a Good Vibe Coding Job

CoStar is explicitly embracing 'vibe coding' to accelerate this greenfield project, making it a perfect fit for developers who prioritize natural language prompting over manual syntax. Because the role focuses on setting new AI-first engineering standards, you'll have the authority to integrate advanced LLM tools into every stage of the lifecycle, from architecture to testing.

The Opportunity

Join CoStar’s elite team to architect a brand-new, enterprise-scale platform where AI isn't an afterthought—it’s the engine. You will be responsible for building resilient distributed systems and crafting intelligent user experiences from the ground up. This is a rare greenfield opportunity within a massive global leader, allowing you to move fast and set the technical direction for years to come.

Tech Stack & AI Integration

The environment is built for modern builders, utilizing a powerful combination of React, Node.js, and C#/.Net across multi-cloud environments. This role is specifically designed for engineers who have moved beyond manual line-by-line coding. You will pioneer vibe coding practices, leveraging LLMs and AI agents to accelerate development, automate testing, and manage complex CI/CD pipelines.

Growth & Impact

Beyond shipping code, you’ll be a cultural architect, mentoring the team on AI-first workflows and human-in-the-loop debugging. As you scale this platform to millions of users, you’ll be at the forefront of redefining the software development lifecycle for the age of generative AI.
