Remote Status: Fully Remote (United States)

🚀 Role Summary

• Product Ownership: Owns end-to-end product features for the Horizon team, focusing on user experience and the product surface of an enterprise-grade MCP gateway. This involves defining user problems, designing flows, and delivering polished, full-stack implemented features.

• Front-End Craftsmanship: Leverages deep front-end engineering expertise in TypeScript and React, with an emphasis on the underlying web technologies, to direct AI development tools and build intuitive user interfaces.

• Strategic Collaboration: Acts as a thought partner within the Horizon team, contributing to shared product and UX direction, and collaborates directly with GtM partners and early customers to translate enterprise signals into actionable product development.

📝 Enhancement Note: This role is framed as a "Product Engineer" with a specific "UI-Focused" emphasis, indicating a hybrid role blending strong front-end engineering skills with product thinking and user experience design. The "Horizon" team context suggests a focus on a specific product line within Prefect, likely related to their MCP (Model Context Protocol) platform, requiring an understanding of enterprise-grade governance and security features. The emphasis on "directing AI tools rather than relying on them" highlights a need for strong technical judgment and engineering fundamentals.
