Job summary

Filevine is seeking a UI Engineer to focus on execution, polish, and UX quality across the Word add‑in and the web app. You’ll work from clearly defined interaction models and design direction set by the Product Design Engineers and Frontend leads, ensuring fast, intentional, and reliable UI experiences.

You’ll care deeply about UI details, understand AI behavior at the UI layer, and be comfortable with streaming states and partial results.

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.

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.
