📋 Description

• Define the technical architecture for Reddit’s prototyping ecosystem. • Architect and maintain a robust, web-based (React, Next.js) prototyping environment. • Partner closely with UXR to drastically reduce the time-to-insight for complex product questions. • Act as the translation layer between Design concepts and Production engineering. • Identify repetitive workflows within the design organization and build internal tools or component libraries to solve them. • Cultivate a culture of technical curiosity within the design team, establishing best practices for prototype engineering, performance, and code quality.

🎯 Requirements

• 5+ years of experience in UX Engineering, Design Technology, or Frontend Development, with a focus on building systems, platforms, or complex internal tools. • Deep expertise in the modern web stack (React, Next.js, Node, Firebase, Cursor). You are comfortable setting up infrastructure and architecture, not just polishing UI. • A portfolio or track record demonstrating the ability to build scalable frameworks, component libraries, or testing environments rather than just single-use websites. • Ability to identify “time sinks” in the design process and autonomously propose and build technical solutions to remove them. • You are a self-unblocker who thrives in ambiguity. You know when to hack for speed to prove a concept and when to engineer for stability to support a platform. • You speak the language of designers. You understand interaction design, accessibility, and the importance of fidelity in user research. • A track record of shipping internal tools or platforms that have measurably improved team efficiency or product outcomes.

🏖️ Benefits

• medical, dental, and vision insurance • 401(k) program with employer match • generous time off for vacation • parental leave
