Frontend AI UI Engineer

Company Description

Organizations everywhere struggle under the crushing costs and complexities of “solutions” that promise to simplify their lives. To create a better experience for their customers and employees. To help them grow. Software is a choice that can make or break a business. Create better or worse experiences. Propel or throttle growth. Business software has become a blocker instead of ways to get work done.

There’s another option. Freshworks. With a fresh vision for how the world works.

At Freshworks, we build uncomplicated service software that delivers exceptional customer and employee experiences. Our enterprise-grade solutions are powerful, yet easy to use, and quick to deliver results. Our people-first approach to AI eliminates friction, making employees more effective and organizations more productive.

And, over 4,500 Freshworks employees make this possible, all around the world.

Fresh vision. Real impact. Come build it with us.

We are looking for a Frontend AI UI Engineer to design and implement highly interactive, intuitive, and enterprise-grade UIs for our Agentic AI Platform. You will collaborate closely with the Principal AI UI Architect to deliver visual interfaces that allow users to build, test, debug, and deploy outcome-driven reasoning agents.

This role involves developing agent builders, simulation tools, dialog orchestration interfaces, and multi-channel assistant deployment UIs, ensuring a seamless developer and enterprise experience.

Key Responsibilities

Agentic UI Development

• Build interactive visual editors (drag-and-drop) for agent orchestration and reasoning workflows (Lang Graph visualization).
• Implement prompt management, versioning, and testing interfaces for agent development.
• Develop real-time debugging tools to visualize agent reasoning traces, tool invocations, and dialog flows.
• Integrate UI components with Lang Smith APIs for agent observability, evaluations, and regression testing.

User Simulation & Testing Interfaces

• Implement user simulation frameworks for testing agent strategies with varied personas and scenarios
• Build A/B testing dashboards for evaluating outcome-driven strategies across agents and prompts.
• Create UIs for multi-turn conversation playback, agent state inspection, and scenario-driven outcome analysis.

Dialog Orchestration & Multi-Channel Experience

• Develop dialog flow editors to design multi-turn conversations with branching, context retention, and hierarchical dialogs.
• Build deployment interfaces to configure assistants across digital channels (chat, web, messaging) and voice/IVR systems

Core UI Framework & Architecture

• Collaborate with the architect to define frontend design patterns, state management, and modular UI frameworks.
• Integrate frontend with backend APIs, agent runtimes, and real-time event streams.
• Ensure UI scalability, performance optimization, and secure multi-tenant design for enterprise usage.

Collaboration & Developer Experience

• Partner with backend engineers to integrate APIs and orchestration services into the UI seamlessly.
• Work closely with UX designers to deliver high-quality, intuitive user interfaces aligned with AI/agent workflows.
• Participate in code reviews, design discussions, and cross-functional planning with architects and engineers.

Please note:
This is a hybrid role that will be based in San Mateo, CA or Bellevue, WA and requires an in-office presence three days per week (Tuesday - Thursday).

Required Qualifications

• 7+ years of frontend engineering experience, building complex enterprise-grade UIs
• Strong expertise in React (e.g., next.js), Type Script, and state management
• Experience developing visual workflow builders or graph-based editors (e.g., d3.js, React Flow)
• Knowledge of real-time UI deployment for live agent monitoring/debugging
• Familiarity with agentic AI concepts and their UI/UX requirements
• Proficiency in frontend testing, performance profiling, and…
