About Vibe

At Vibe.co, we're reimagining how brands reach audiences in the age of streaming. We believe streaming TV is no longer just a brand awareness play, it's the next great performance marketing channel. We're building the infrastructure to unlock this $100B opportunity.

Vibe.co provides an Audience First Streaming TV Advertising solution for marketers to unlock TV as a growth channel. Our all-in-one solution combines hyper-targeted audience segmentation, AI-powered insights and recommendations, real-time campaign optimization, and incrementality measurement, giving brands of all sizes the precision and transparency they've come to expect from social and search, but on TV.

Trusted by over 10,000 brands, Vibe.co reaches more than 120 million households across 500+ apps and channels, delivering an average 250% return on ad spend and 20% sales lift. The company hit a $100 million revenue run rate in under two years, ranking among the ten fastest software companies to reach that milestone.

Vibe.co's investors include Hedosophia (an early backer of Spotify, Uber, and Airbnb), Elaia, Singular, QuantumLight (Revolut CEO Nik Storonsky's fund), and Illusian (Supercell CEO Ilkka Paananen's fund), as well as angel investors including Carolyn Everson, board member of The Walt Disney Company and Coca-Cola. Nirav Tolia, CEO of Nextdoor, sits on the company's board of directors.

Founded in 2022, Vibe.co is widely recognized as the category-defining platform in streaming TV advertising, bringing the power of Meta and Google-style performance marketing to the fastest-growing segment in media.

About the Role

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.

What You'll Do

Architecture & Standards

• 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

What You Need

• 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
