Job description

Engineering · San Francisco Bay Area · FullTime · Senior level

This is a hands on staff level role leading frontend work for a voice AI platform, from defining the problem through architecture, build and launch. A strong candidate brings many years of frontend engineering, deep React and TypeScript skill, and a record of shipping complex web apps while explaining the tradeoffs behind decisions. The work also calls for mentoring, solid code reviews, and close partnership with product and design to turn complicated workflows into clear interfaces.

How it fits the AI era

The product itself is AI voice agents, so the frontend is where customers configure, deploy and monitor those agents, which means the interfaces must make AI behavior understandable and controllable. AI tools can speed up routine coding, but the judgment about architecture, usability, accessibility and performance stays with the engineer. The human part is simplifying messy workflows and making real time data readable at a glance.

How it builds AI experience

Working here means building the screens people use to set up and watch AI voice agents, so the role offers direct exposure to how AI products are operated in practice. A candidate can prepare by studying how agent configuration, dashboards and analytics are designed, and by trying the company's own platform and API to see the workflows firsthand. Bonus areas worth showing include real time interfaces, data visualization and developer tools.

Worth showing

• React and TypeScript depth
• Frontend architecture ownership
• Accessibility and performance
• Mentoring and code review
