Member of Technical Staff – Frontend

About the Role

As a frontend engineer at Inflection, you will craft intuitive, responsive, and elegant interfaces that bring our LLM-powered products to life. You’ll work hand-in-hand with product, research, and design teams to build rich user experiences—from rapid prototypes to scalable production apps—that showcase the capabilities of our conversational AI.

This is a good role for you if you:

• Have 4+ years of experience building and maintaining production-grade web applications
• Are fluent with React, TypeScript, and frontend performance debugging tools (e.g., Lighthouse, Chrome DevTools, Web Vitals)
• Have built interactive UIs from scratch—ideally with experience handling real-time updates, accessibility, and responsive design
• Understand the trade-offs between UX richness, responsiveness, performance, and maintainability
• Have designed systems that balance experimentation and rapid iteration with long-term scalability
• Are energized by working in a fast-moving, cross-functional environment with deep technical challenges
  
  

Responsibilities include:

• Design and build performant, maintainable frontend systems using TypeScript, React, and modern web tooling
• Collaborate with researchers to surface advanced model behaviors—including tool use, RAG, and personalization—through intuitive UX paradigms
• Develop and maintain internal UI components and design systems used across multiple product surfaces
• Integrate real-time data and analytics pipelines to visualize assistant behavior, model performance, and user feedback
• Build developer infrastructure to support fast iteration cycles: hot reloading, component testing, E2E automation, and visual diffing
• Work across the stack with backend and platform teams to ship end-to-end features with minimal latency and maximum reliability
• Contribute to a culture of high code quality, continuous improvement, and shared ownership
