Full Stack Engineer - Frontend Architecture

Vibe’s product runs on a frontend that’s grown faster than its architecture has. You’ll join the Web Platform team, reporting to [Hiring Manager Name], [Title], with a mandate to give that architecture the structure it needs to support the next phase of growth. This role exists because the product surface area - dashboards, campaign tools, reporting, real-time data - has outgrown ad hoc patterns, and someone needs to own the fix. You’ll get a rare mix: the technical depth of defining state management and component architecture from scratch, the influence of setting standards a whole team will use, and direct collaboration with design to close the gap between Figma and production. If you want to shape how a fast-growing product gets built rather than just build features on top of it, this is that role., * Define a scalable approach to frontend state management across the application

• Establish frontend coding standards and development patterns for the team
• Set clear boundaries between UI components, business logic, state, and data fetching
• Lead technical decisions on frontend architecture and explain the trade-offs behind them

Build & Improve

• Improve maintainability, testability, and performance of the frontend codebase
• Build reusable components that raise consistency across the product
• Contribute to backend services and APIs when the work calls for it

Design Systems & Collaboration

• Drive adoption of the design system across product surfaces
• Turn Figma designs into production-ready experiences with designers
• Explore AI-assisted workflows that speed up design-to-implementation handoff

Team Impact

• Review code to raise the frontend bar across the team
• Mentor engineers on frontend architecture and best practices

• Experience defining or significantly improving the architecture of an existing frontend codebase
• Advanced knowledge of TypeScript and a modern frontend framework, ideally React
• Practical experience solving state-management problems at scale - local, shared, server, and URL state
• Experience building, integrating, or maintaining a design system
• Comfortable working across the stack, including APIs, data models, and backend architecture
• A track record of introducing standards or patterns that other engineers adopted

Nice to Haves

• Experience with AI-assisted development or design-to-code tools
• Experience modernizing a legacy or fast-growing frontend codebase
• Experience integrating Figma or a similar design tool into the development workflow
• Experience in a fast-moving product or startup environment
