Responsibilities
Shape the vision: Define the technical architecture for Reddit’s prototyping ecosystem. You will lead the strategy for how we transition from static designs to interactive, data-driven experiments
Build the platform: Architect and maintain a robust, web-based (React, Next.js) prototyping environment. This infrastructure must be flexible enough to allow for dynamic swapping of screens and journeys for scaled A/B testing
Accelerate velocity: Partner closely with UXR to drastically reduce the time-to-insight for complex product questions. You will automate the “grunt work” of testing, building tools that allow us to deploy quantitative tests to hundreds of users with minimal overhead
Bridge the gap: Act as the translation layer between Design concepts and Production engineering. You will manage real data flows to create experiences that feel authentic, ensuring we are testing relevance rather than “happy-path” illusions
Tooling leadership: Identify repetitive workflows within the design organization and build internal tools or component libraries to solve them. If we are building it twice, you build the tool that automates it
Mentorship: Cultivate a culture of technical curiosity within the design team, establishing best practices for prototype engineering, performance, and code quality
Qualification
Required
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
