$175K/yr - $225K/yrDelphi is redefining how knowledge is shared by creating a new medium for human communication. The Design Engineer will build user-facing features, design a discovery platform, and ensure high-quality front-end systems while collaborating closely with cross-functional teams.
Artificial Intelligence (AI)EducationSoftware
Responsibilities
Build the core interfaces of Delphi Studio - Own and ship the primary user-facing features: creation flows, customization tools, and interaction patterns. You'll write the React components, build the APIs integrations, and polish every detail
Create a discovery platform for digital minds - Design and implement the browsing experience, search functionality, filtering systems, and recommendation interfaces. Make exploring thousands of AI personas feel effortless and delightful
Architect scalable front-end systems - Build reusable component libraries, establish patterns for state management, optimize bundle sizes, and ensure the app performs beautifully at scale
Translate AI complexity into simple UX - Work directly with product and backend engineers to understand AI capabilities, then build interfaces that expose the power while hiding the complexity
Set the standard for quality - Your code will be the example others follow. Write clean TypeScript, build accessible components, implement smooth animations, and establish the bar for what 'production-ready' means
Collaborate across disciplines - Partner closely with designers to refine mockups and improve interactions. Work with backend engineers to define API contracts. Sync with product to shape roadmap priorities
Qualification
Required
Code-first builder with exceptional design taste - You're a front-end engineer who happens to have a great eye for design
Master of the modern web stack - React, Next.js, TypeScript, and Tailwind aren't just tools you use—they're tools you've mastered
Obsessive about craft and details - You notice when animations feel off by 50ms, when a loading state causes layout shift, or when a color doesn't meet WCAG standards
Full-stack front-end engineer - Comfortable working across the entire front-end stack, from API integration and state management to responsive layouts and micro-interactions
Owner, not executor - You prototype quickly, gather feedback, iterate fast, and ship confidently
Product-minded engineer - You push back on designs that don't serve users, suggest improvements to the product direction, and think deeply about user flows
Comfortable in ambiguity - You thrive when the problem space is undefined
