Senior Software Engineer, Frontend (UI) – San Francisco

Flow Engineering is an AI-native requirements platform that is transforming how complex hardware is built by integrating world-class engineers with AI agents. They are seeking a senior frontend software engineer to enhance user experiences and implement AI-powered workflows in a clean, intuitive UI.

Responsibilities:

• Own major user-facing surfaces in Flow v3, including interactive requirements views, collaboration and review flows, and AI-assisted workflows
• Implement high-quality, accessible UI using a modern frontend framework and component system
• Integrate AI features into the product in ways that feel natural, interpretable, and helpful to engineers
• Partner with design and product to iterate quickly on interaction patterns, prototypes, and new workflows
• Help shape frontend architecture, design systems, and performance optimizations as the app and user base scale

Requirements:

• 5+ years of experience building rich, data-heavy web applications with a modern frontend framework
• Strong experience with React (or similar) and TypeScript, including component design, state management, and testing
• A product mindset: you think in terms of user journeys, edge cases, and clarity, not just individual screens
• Comfortable collaborating closely with design and product, and giving and receiving feedback through iterations
• Willingness to occasionally work across the stack (e.g., refining APIs, wiring up integrations) to ship features end-to-end
