UI Engineer

Join our team as a UI Engineer, where you'll focus on execution, polish, and UX quality across our Word add-in and web app. This engineering-first role requires strong frontend engineering skills with React and TypeScript, and a high standard for UI polish and interaction quality. You'll work closely with Product Design Engineers and Frontend Engineers to ensure design intent is preserved in implementation, and you'll have the opportunity to make an impact on Day 1.

• Implement high-quality UI across the Word add-in and web app using React and TypeScript, focusing on execution, polish, and UX quality.
• Improve interaction quality for AI-driven workflows, including loading states, streaming output, retries, and error handling.
• Work closely with Product Design Engineers and Frontend Engineers to ensure design intent is preserved in implementation, and make AI behavior feel understandable, predictable, and trustworthy at the UI layer.
• You should care deeply about details, understand how AI systems behave at the UI layer, and be comfortable working with streaming states, partial results, and failure modes without papering over them
• A bias toward fixing what’s broken instead of working around it
• Enough system-level understanding to reason about latency, failures, and partial results
• Experience with complex, user-facing products where UX quality mattered
• Strong frontend engineering skills with React and TypeScript
• Ability to take direction clearly and execute with precision
• Comfort working with async systems, streaming data, and non-deterministic states
• High standards for UI polish, interaction quality, and visual consistency
• Familiarity with Microsoft Word add-ins or similar environments
• If you care about clean UI, strong execution, and making complex systems feel simple, we’d like to talk
• Experience building for constrained or embedded surfaces like plugins, extensions, or add-ins
• Experience with AI-powered products or systems with streaming or long-running workflows
