Role Summary:

We’re looking for a UI Engineer to focus on execution, polish, and UX quality across the Word add-in and the web app. This role is engineering-first. You won’t own UX strategy or define workflows from scratch. Instead, you’ll work from clearly defined interaction models and design direction set by the Product Design Engineer and Frontend leads, and make the product feel fast, intentional, and reliable.

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.

Responsibilities

  • Implement high-quality UI across the Word add-in and web app using React and TypeScript
  • Improve interaction quality for AI-driven workflows, including loading states, streaming output, retries, and error handling
  • Reduce UX friction across the product by fixing layout issues, state inconsistencies, spacing problems, and rough edges
  • Apply and extend existing design patterns and component systems consistently
  • Work closely with Product Design Engineers and Frontend Engineers to ensure design intent is preserved in implementation
  • Make AI behavior feel understandable, predictable, and trustworthy at the UI layer
  • Move quickly on UI fixes and improvements without waiting on heavy product or design processes

    • Qualifications

  • Strong frontend engineering skills with React and TypeScript
  • High standards for UI polish, interaction quality, and visual consistency
  • Comfort working with async systems, streaming data, and non-deterministic states
  • Enough system-level understanding to reason about latency, failures, and partial results
  • Ability to take direction clearly and execute with precision
  • A bias toward fixing what’s broken instead of working around it
  • Experience with complex, user-facing products where UX quality mattered

    • Nice to Have

  • Experience with AI-powered products or systems with streaming or long-running workflows
  • Experience building for constrained or embedded surfaces like plugins, extensions, or add-ins
  • Familiarity with Microsoft Word add-ins or similar environments

    • What's In It For You

  • You’ll work on a flagship AI product used daily by legal teams
  • You’ll ship frequently and see your work live in production
  • You’ll collaborate with senior engineers and product leaders in a tight feedback loop
  • You’ll help shape a UI that users actually trust

    • If you care about clean UI, strong execution, and making complex systems feel simple, we’d like to talk.
