Hume AI is a Series B startup focused on building AI optimized for human well-being, including speech language models, audio understanding models, and enterprise evaluation platforms.

Requirements

• Significant professional experience building production web applications.
• Strong proficiency with TypeScript, React, and Next.js.
• Strong understanding of modern JavaScript, HTML, CSS, browser rendering, caching, and frontend performance.
• Strong product and UI intuition, particularly for AI-powered applications where interactions and information hierarchy may differ from traditional deterministic web applications.
• Experience designing maintainable frontend architectures, including application state, data fetching, and data flows.
• Experience building responsive, accessible, and polished user interfaces.
• Experience with automated frontend testing, including unit, integration, and end-to-end testing.
• A strong sense of ownership and the ability to make pragmatic engineering decisions independently.
• Excellent written and verbal communication skills.
• Ability to use AI-assisted coding tools effectively while retaining ownership of resulting code, including explaining, validating, debugging, and modifying it independently when necessary.

Nice To Haves

• Experience building developer-facing products, dashboards, consoles, or API platforms.
• Experience with WebSockets, WebRTC, streaming APIs, or other real-time applications.
• Experience working with audio, video, visualization, or other rich interactive media.

• Experience with frontend performance profiling, observability, or testing infrastructure.
• Experience with Playwright or similar end-to-end testing frameworks.
• Experience integrating authentication and authorization systems such as Auth0.
• Familiarity with AI or machine-learning products.

Responsibilities

• Design, build, and maintain production web applications using TypeScript, React, and Next.js.
• Build intuitive interfaces for Hume’s voice AI products, developer platform, and enterprise tooling, including interfaces that surface real-time model behavior, system state, and AI-specific interactions.
• Develop reusable frontend components and shared engineering patterns.
• Integrate frontend applications with APIs, WebSockets, and real-time services.
• Build and maintain automated frontend tests.
• Diagnose and improve frontend reliability, performance, and usability.
• Collaborate closely with product and design to ship polished user experiences.
• Write clear technical documentation for systems and features.
